Q. The amount of heat required to change from liquid state to gaseous state without rise in its temperature is called latent heat of vaporisation.

Q. The graph shows the variation of temperature (T ) of one kilogram of a material with the heat (H) supplied to it. At O, the substance is in the solid state rom the graph, we can conclude that

Q. For many substances, there exists a temperature

T_{t r}

. and a pressure ptr at which all the three phases of a substance (gaseous, liquid, and solid) are in equilibrium. These temperature and pressure are known as the triple point. For example,

T_{t r} = {0.0075}^{\circ} C

p_{t r} = 4.58 m m

Hg for water. The latent heat of vaporization of water at the triple point is

q = 2.48 \times 10^{3} k J / k g

, and the latent heat of fusion of ice is

λ = 0.34 \times 10^{3} k J / k g
