Question 209

The specific heat capacity of liquid A is less than that of liquid B.

What does this statement mean?

A

More energy is needed to raise the temperature of unit mass of liquid A by 1 ∘C1\text{ }^{\circ}\text{C}1 ∘C than unit mass of liquid B.

B

Less energy is needed to raise the temperature of unit mass of liquid A by 1 ∘C1\text{ }^{\circ}\text{C}1 ∘C than unit mass of liquid B.

C

More energy is needed to vaporise unit mass of liquid A than unit mass of liquid B at its boiling point.

D

Less energy is needed to vaporise unit mass of liquid A than unit mass of liquid B at its boiling point.
