A liquid at 30°C is poured verly slowly into a Calorimeter that is at temperature of 110°C. The boiling temperature of the liquid is 80°C. It is found that the first 5 gm of the liquid completely evaporates. After pouring another 80 gm of the liquid the equilibrium temperature is found to be 50°C. The ratio of the Latent heat of the liquid to its specific heat will be ____C°.
[Neglect the heat exchange with surrounding.]

Answer

`270.00`

Explanation

`5(s)(80-30)+5L=C(110-80)`, where C is heat capacity of calorimeter
`rArr250s+5L=3C,80(s)(50-30)=C(80-50)`
`rArr16000s=30C therefore250s+5L=1600srArr5L=135rArr(L)/(s)=270`
