Properties of Water - total

Front

What property of water gives certain insects the ability to walk on water?

Back

Surface tension is the property of water that allows certain insects, like water striders, to walk on its surface without sinking.

Front

The amount of energy needed to change one gram of a liquid substance into a gas is called the heat of _____________.

Back

Vaporization.

Front

What property of water enables it to interact with other polar substances?

Back

Polarity allows water to interact with other polar substances, making it an effective solvent.

Front

True or False: Liquid water is more dense than ice (solid water).

Back

True. Liquid water is denser than ice, which is why ice floats.

Front

True or False: Hydrogen bonds between water molecules give water a high level of cohesion.

Back

True. Hydrogen bonds create strong cohesive forces between water molecules.

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

Front

Define adhesion in the context of water.

Back

Adhesion is the property of water that allows it to stick to other substances, such as plant cell walls.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to cohesion and adhesion.

Front

Explain the significance of water's high specific heat.

Back

Water's high specific heat means it can absorb a lot of heat without a significant change in temperature, helping to regulate climate.

Front

What is the effect of temperature on the density of water?

Back

As water cools, it becomes denser until it reaches 4°C; below this temperature, it expands and becomes less dense.
