DOK Level 2: Skill/Concept

Explain why water is often used as a coolant in industrial processes.

• Because it is cheap and readily available

• Because it has a high specific heat capacity, allowing it to absorb a lot of heat without a significant rise in temperature

• Because it is a good conductor of electricity

• Because it is non-reactive with most metals
