Question 28

The specific heat capacity of liquid $X\,$ is less than that of liquid $Y$ .

What does this statement mean?

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

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

Less energy is needed to vaporise unit mass of liquid $X$ than unit mass of liquid $Y$ .

More energy is needed to vaporise unit mass of liquid $X$ than unit mass of liquid $Y$ .
