Water Properties, Energy Transfer and Coriolis Effect

Front

What is the chemical formula for water?

Back

H2O (Dihydrogen Monoxide)

Front

What happens to water when it freezes?

Back

Water expands when it freezes, which can break containers.

Front

What is the property of water that allows it to hold more drops on a penny compared to other liquids?

Back

Cohesion due to hydrogen bonding.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects caused by the rotation of the Earth.

Front

How do high-pressure systems affect wind direction?

Back

Winds circulate clockwise in high-pressure systems in the Northern Hemisphere.

Front

What is the difference between fresh water and saltwater in terms of density?

Back

Saltwater is denser than fresh water due to the dissolved salts.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds give water its unique properties, such as high surface tension and specific heat.

Front

What happens to the density of water as it freezes?

Back

The density of water decreases as it freezes, which is why ice floats.

Front

What is the term for the amount of energy required to change water from liquid to gas?

Back

Latent heat of vaporization.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane.
