Question 32

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

What does this statement mean?

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

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

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

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