A metal pot on a stove becomes painfully hot long before the water inside it warms up. Which property of water explains this?
AIts high specific heat
BIts low specific heat
CIts high vapour density
DIts low freezing point
Answer & Solution
Correct answer: A. Its high specific heat
1. Specific heat is the heat energy needed to raise the temperature of a unit mass by one degree.
2. Water has a high specific heat, so a lot of energy must be absorbed before its temperature changes.
3. The strong hydrogen bonds between water molecules have to be disrupted first.
4. The metal of the pot has a much lower specific heat and so heats up quickly.
