Lesson 5: The Properties of Water (Part 2)

Here are some more properties you need to remember!

High Heat Capacity

Specific heat capacity is the amount of energy required to change 1 gram of a substance by 1℃.

Water has a high specific heat capacity – this is because it has to absorb large amounts of heat energy before it begins to get hot, it also releases heat energy slowly.

It has strong adhesive forces

Adhesive forces are attractive forces that occur between two, unlike substances. This means that when water is in a tube, it is more strongly attracted to the tube than to itself (this is called cohesion).

This is useful for evapotranspiration – tiny tubes in the roots suck up water, the xylem transports water through the plant and finally, water leaves the plant through stomata.
