$\frac{P_1}{V_1}$ = $\frac{V_2}{T_2}$
= $\frac{200}{293}$ = $\frac{V_2}{353}$ = V2 = 240.96 ml

- In an experiment to determine the specific latent of vapourization of water, steam of mass 10 g at 100o ...(Solved)
In an experiment to determine the specific latent of vapourization of water, steam of mass 10 g at 100o is passed into 100 g of water initially at 20oC in a container of negligible heat capacity. The temperature of the water rises to 70oC.
(Take the specific heat capacity of water as 4.2 x 103J Kg-1 and boiling point of water as 100oC)
i) Determine the specific latent heat of vapourization of water
ii) State two sources of error in this experiment.
