Properties of Water - Post Lab

Front

What is the characteristic of water that allows a paperclip to float on its surface?

Back

Surface tension is the characteristic of water that allows a paperclip to remain floating on the surface.

Why do water molecules stick together?

Back

Water molecules stick together because one side has a positive charge and the other side has a negative charge.

Front

What two elements make up water?

Back

Water is made up of hydrogen and oxygen.

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.

Why does ice float on liquid water?

Back

Ice floats on liquid water because water's solid form is less dense than its liquid form.

Front

What is surface tension?

Back

Surface tension is the property of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.

Front

What is cohesion in the context of water?

Back

Cohesion refers to the attraction between water molecules, which allows them to stick together.

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances, which allows water to climb up surfaces.

Front

What is the significance of water being a polar molecule?

Back

Water being a polar molecule means it has a partial positive charge on one end and a partial negative charge on the other, allowing it to interact with other polar substances.

How does water's high specific heat benefit the environment?

Back

Water's high specific heat helps regulate temperature in the environment, allowing for stable climates.
