Properties of Water

Question 7 • *STPSB_Environmental Science 2627

Which best explains why water has a high specific heat?

Answer
A
Hydrogen bonds decrease the amount of energy that is required for the temperature to change.
B
Hydrogen bonds increase the amount of energy that is required for the temperature to change.
C
Ion-dipole interactions increase the amount of energy that is required for the temperature to change.
D
Ion-dipole interactions decrease the amount of energy that is required for the temperature to change.

Explanation

Water molecules form hydrogen bonds with one another. Added heat must first provide energy to disrupt or weaken these attractions before it can increase the molecules’ motion and temperature, so water requires more energy for a given temperature change. Therefore, hydrogen bonds increase the amount of energy required for the temperature to change.
