Why does water have a high specific heat?
A.Energy first breaks hydrogen bonds before molecules speed up
B.Water molecules are very heavy
C.Water has no intermolecular forces
D.Water is a gas at room temperature
Explanation
Core Concept
Added heat goes into disrupting the hydrogen-bond network, so temperature rises slowly per joule. This buffers organisms and climates against rapid temperature swings.
Correct Answer
AEnergy first breaks hydrogen bonds before molecules speed up
