Water Properties, Energy Transfer and Coriolis Effect

Front

What is the property of water that allows it to form hydrogen bonds?

Back

Water is a polar molecule, meaning it has a partial positive charge on one side (hydrogen atoms) and a partial negative charge on the other side (oxygen atom), allowing it to form hydrogen bonds.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water, due to the rotation of the Earth. In the Northern Hemisphere, objects are deflected to the right, and in the Southern Hemisphere, they are deflected to the left.

Front

How does temperature affect the density of water?

Back

As water cools, it becomes denser until it reaches 4°C. Below this temperature, water begins to expand, making it less dense, which is why ice floats.

Front

What phase change occurs when water vapor turns into liquid water?

Back

Condensation.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds give water its unique properties, such as high surface tension, high specific heat, and the ability to dissolve many substances.

Front

What happens to the temperature of water during the phase change from liquid to gas?

Back

The temperature remains constant during the phase change (vaporization) until all the liquid has turned into gas.

Front

What is the main reason for the Coriolis effect?

Back

The Coriolis effect is primarily caused by the rotation of the Earth, which affects the direction of winds and ocean currents.

Front

What is the relationship between temperature and the kinetic energy of water molecules?

Back

As the temperature of water increases, the kinetic energy of its molecules also increases, causing them to move faster.

Front

What is the process called when water changes from a solid to a liquid?

Back

Melting.

Front

What is the main reason that saltwater has a higher density than freshwater?

Back

Saltwater contains dissolved salts, which increase its mass without significantly increasing its volume, resulting in higher density.
