$A$ solution consists of ether and $5.0 \ g$ of water at $0^{\circ} C$. If the ether evaporates completely to freeze the water,then the mass of the ether in the solution is (in $g$)

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 $L_f$	$(ii)$ $33.3 \times 10^5 \, J/kg$
	$(iii)$ $3.33 \times 10^5 \, J/kg$

$A$ solid cube having certain fixed melting and boiling points takes heat from some source. The variation of temperature $\theta$ of the cube with the heat supplied $Q$ is shown in the adjoining graph. The portion $BC$ of the graph represents the conversion of

$A$ quantity of heat required to change the unit mass of a solid substance,from solid state to liquid state,while the temperature remains constant,is known as

When $0.93 \, W \cdot h$ of energy is supplied to a block of ice weighing $10 \, g,$ it is found that

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