  • Reading Articles: Water Anomaly

    Reading Articles: Water Anomaly

    Water has a number of exceptional properties, which distinguish it from other fluids. One is the anomaly of density.

    The Behaviour of Water at Different Temperatures

    Usually, substances expand when they are heated. But if you heat water starting at 0°C, you will notice something weird: At first, the volume of the liquid does not get bigger, but smaller! Up to a temperature of 4°C, the water contracts when heated.

    Once it has reached that temperature, it starts to expand with increasing temperature just like other fluids. That means water has a higher density at 4°C than at any other temperature.

    Why does ice need more space than cold water?

    When cooling down below 4°C, water expands. When it freezes at 0°C, the volume increases once again. This unusual behaviour has something to do with the structure of solid and liquid water: In the liquid, the molecules can move relatively freely, whereas in ice, they assemble into regular structures with big hollow spaces in between, which require more space.

    Since ice has a lower density than water, it floats on the water. You know this from ice cubes in a drink or from icebergs floating in the sea.

    The Anomaly Determines Life on Earth!

    Thanks to the anomaly, fish can survive in stretches of standing water in winter! Since water with a temperature of 4°C is heavier than colder water, it sinks downwards. Therefore, it is warmer on the bottom of the lake than on the surface. On top it is the coldest.

    As a result, the lake starts to freeze from the top to the bottom, and the warmer layers of water beneath the sheet of ice cool down considerably more slowly and remain liquid. There, the aquatic animals can spend the winter. If the water froze from the bottom to the top, soon the whole water would have frozen and the fish would have no chance to survive!

    The anomaly also has its drawbacks, though:

    If water is enclosed in a closed vessel, it still expands while freezing and may develop such forces that it bursts the vessel. Water enclosed in rock cracks is even able to break up the rock, and therefore plays an important role in the erosion process. In the same way, frost damage is caused on the streets when water seeps into the cracks of the road surface and freezes.

    Water must also be prevented, from freezing in water pipes during winter, since otherwise the pipes burst.

  • Why Does a Ship Float in Water?

    Why Does a Ship Float in Water?

    When I jump into a swimming pool, I sink like a stone unless I flail about wildly, but when the USS Enterprise aircraft carrier – which is just a tad bigger and tad heavier than I am – jumps into the ocean, it floats with no effort whatsoever. What’s going on? Let’s wonder a bit about the science of floating.

    Some big, heavy things – like the USS Enterprise – float in water. Some small, light things, like a ball bearing, don’t. So size doesn’t determine whether something floats, and neither does weight. Let’s start by identifying what causes something to float or not.

    Everything on Earth, whether on the surface or under water, has the weight of everything higher up pushing down on it.

    Everything on Earth, whether on the surface or under water, has the weight of everything higher up pushing down on it. Yes, right now as you read this, the weight of all of the air above you, right up to the top of the atmosphere, is pushing down and in on you. The resulting force is about 14.7 pounds on every square inch of your body. 14.7 pounds per square inch, or psi, is the normal, average atmospheric pressure on the Earth.

    If you dive down into water, you’ll not only have the weight of the air up above pushing in on you, but the weight of all of the water above you as well. Water is relatively heavy – go down just 30 feet and the weight of the water per square inch on your body will equal the weight of the hundreds of miles of air above you. 

    Why doesn’t the weight of all that air and water push you down, down, down, after you dive into a swimming pool? The answer is simply that the water below you is pushing up. 

    There you are, underneath the surface in a swimming pool. Water wants to be where you are – your body has displaced a whole lot of it. If you suddenly disappeared, water would rush in to fill the space. It is the force of that potential “rushing in” that results in a force acting against the weight of the air and water above you.

    This is the buoyant force. The buoyant force depends on how much water an object displaces. The larger the object, the greater the buoyant force it experiences. Ah, but will that object float? 

    An object floats when the buoyant force is large enough to counter the object’s weight. So a large hollow object might float because large means more water displaced – so more buoyant force – and hollow means relatively little weight. A small solid object might not float, however. Less water displaced results in a smaller buoyant force. If that buoyant force isn’t enough to counter the weight of the object, it will sink. 

    So yes, the USS Enterprise weighs far more than I do. But the weight of the water it displaces is more than the weight of the aircraft carrier, so it floats. Me, I weigh more than the water I displace, so I sink.

  • Reading Article: Oceans Current

    Reading Article: Oceans Current

    Learning Objectives:
    1. Know what is meant by an ocean current.
    2. Distinguish between surface and deep currents.
    3. Explain why our Pacific Coast is cool and dry and our Atlantic Coast is warm and wet.

    Ocean currents are streams of water that flow through the ocean. There are two types of ocean currents; surface and deep currents.

    Surface Currents

    Surface currents are powered by the sun and driven by the wind. The sun drives the global wind systems on Earth. When this wind blows over the surface of the ocean, it causes waves to form and the water at the surface to move. The force of the wind pushing on the water results in what are known as surface currents.

    The global winds that drive surface currents are affected by a number of things, one of which is the rotation of the Earth. The Earth’s rotation causes the ocean currents to turn in a process known as the Coriolis effect. Because of the Coriolis effect, ocean currents deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

    Additionally, while the wind only pushes the water at the very surface of the ocean, the water molecules moved by the wind current drag along the water molecules just below them. The result is that the layer of water just below the surface also moves (though slightly slower). That second layer, in turn, pulls on the water molecules below it. This continues down to a depth of about 100 m (330 feet) with each increase in depth resulting in a slowing down of the water.

    Deep Ocean Currents

    Deep ocean currents (currents that occur at depths below those of surface currents) are driven by differences in seawater density which are the result of differences in temperature and salinity (saltiness). The system of deep ocean currents that is the result of these changes in density is known as the global conveyor belt

    The Global Conveyor Belt:

    Near the pole of the North Atlantic, water near the surface of the ocean begins to freeze due to cold temperatures. When this water freezes, however, it leaves salt behind, which increases both the salinity and density of water left behind (not frozen). This denser water begins to sink to the bottom of the ocean, while surface water moves in to replace it, generating a current. This deep water then moves south in a complex pattern around the globe, moving at speeds much slower than those of the surface currents.

    Arus Air panas dan Dingin di Samudra

    How Ocean Currents Affect the Coast:

    Ocean currents can affect local coasts by transferring heat (in the form of warm water) from warmer (tropical) to colder (polar) regions.

    For example, currents flowing from the poles (think Alaskan and northern ocean currents; these currents are coming from cold regions) travel southward along the west coast (Pacific Coast) of the United States, causing cooler ocean temperatures and a cooler climate. The cold current along the west coast of the US is known as the California current. On the other hand, currents from locations near the equator (think the Caribbean and tropical Atlantic; these currents are coming from warm regions) move along the east coast (Atlantic Coast), resulting in a warm and wet climate.

    1. Tidak boleh diikuti dengan kata verb tapi bisa dengan gerund
      1. She has been banned from driving for a month.
    2. Untuk object of preposition berbentuk relative pronoun, Preposition berada di bagian belakang :
      1. Here is the micrometers that you asked for
      2. It is the chance that he fight for
    3. Untuk object of preposition berbentuk interrogative pronoun maka posisi preposition juga berada di bagian akhir kalimat :
      1. What are you looking for?
      2. Which is side you on?
      3. What is going on?
    4. Untuk object of preposition berbentuk infinitive maka preposition berada setelah infinitive.
