Boiling water is changing into steam. The specific heat of boiling water is

Values for latent heat in Column-$I$ and its values are given in Column-$II$. Match the following:

Column-$I$	Column-$II$
$(a)$ Latent heat of vaporization $L_V$	$(i)$ $22.6 \times 10^5 \, J/kg$
$(b)$ Latent heat of fusion $L_f$	$(ii)$ $33.3 \times 10^5 \, J/kg$
	$(iii)$ $3.33 \times 10^5 \, J/kg$

Latent heat of ice is $80 \, cal/g$. $A$ man melts $60 \, g$ of ice by chewing in $1 \, minute$. His power is ........ $W$.

What is the process of changing the state of matter called?

Two substances $A$ and $B$ of equal mass $m$ are heated at a uniform rate of $6 \, cal \, s^{-1}$ under similar conditions. $A$ graph between temperature and time is shown in the figure. The ratio of heat absorbed $H_A/H_B$ by them for complete fusion is

Boiling water is changing into steam. Under this condition,the specific heat of water is
