Correct Answer - 2 g ice
At the stage of thermal equilibrium at `0^(@)C`
heat lost by water=Heat absorbed by ice to melt.
`msDeltaT=mL`
`100xx1xx40=mxx80`
`m=50g`
Remaining ice`=52-50=2g`

At `27^@C` latent heat of `I^-` fusion of a compound is `2.7xx10^3 J mol^(-1)`. Calculate the entropy change during fusion.

Correct Answer - A Entropy , `DeltaS_(f) =(DeltaH_(f))/(T_(f))=("Fusion enthalpy")/("Temperature")` `DeltaS_(f)=(2930 J "mol"^(-1))/(300 K)=9.77 JK^(-1) "mol"^(-1)`

The specific heat at constant volume for a gas is 0.075 cal/g and at constant pressure it is 0.125 cal/g. Calculate, (i) the molecular weight of gas,

(i) `C_(P)-C_(V)=(R)/(M)` where, M=molecular of gas `0.125-0.075=(1.987)/(M)` `M=39.74~~40` (ii) `(C_(P))/(C_(V))=gamma` `therefore=(0.125)/(0.075)=1.66` `therefore` 1.66 value of `gamma` shows that the gas is monoatomic.
