Water properties

Front

What is a polar molecule?

Back

A molecule in which opposite ends have opposite electric charges, such as water.

Front

Why is it beneficial for ice to float?

Back

It allows fish to swim underneath the ice, providing a habitat and protecting them from extreme cold.

Front

How do large bodies of water affect nearby climates?

Back

They absorb heat in the summer and slowly release that heat in the winter, moderating temperature fluctuations.

Front

What is the reason large bodies of water do not quickly fluctuate in temperature?

Back

Water has a high heat capacity, meaning it can absorb and store a lot of heat without a significant change in temperature.

Front

Which end of the water molecule has a slightly positive charge?

Back

The hydrogen end of the water molecule has a slightly positive charge.

Front

What is cohesion in the context of water?

Back

Cohesion is the property of water that allows it to stick to itself, leading to phenomena like surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances, which is important for processes like capillary action.

Front

What is the significance of water's high heat of vaporization?

Back

It allows organisms to cool down through processes like sweating, as it takes a lot of energy to convert water from liquid to gas.

Front

What role do hydrogen bonds play in water's properties?

Back

Hydrogen bonds are weak attractions between water molecules that contribute to water's unique properties, such as high surface tension and heat capacity.

Front

What is the definition of a solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution; water is known as the universal solvent.
