Back

less

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and different substances.

Front

What is surface tension?

Back

Surface tension is the cohesive force between water molecules at the surface, allowing it to resist external force.

Front

Why does ice float on water?

Back

Ice is less dense than liquid water due to the arrangement of water molecules in a solid state.

Front

What is a polar molecule?

Back

A polar molecule has a partial positive charge on one side and a partial negative charge on the other, like water.
