Question 302

An electric heater is used to heat equal masses of two different liquids, Liquid A and Liquid B, under identical conditions. The temperature of Liquid A is observed to rise more slowly than the temperature of Liquid B.

What is a possible explanation for this difference?

A

Liquid A has a lower boiling point than Liquid B.

B

Liquid A has a lower latent heat of vaporisation than Liquid B.

C

Liquid A has a larger thermal expansion coefficient than Liquid B.

D

Liquid A has a higher specific heat capacity than Liquid B.
