of water at is contained in a thermally insulated container. Now the air from the vessel is pumped out adiabatically. A fraction of water gets converted into ice and the remaining evaporates at itself. The mass of evaporated water will be closest to [Take the latent heat of vaporization of water, and latent heat of fusion of water, ]
Options
- A
- B
- C
- D
Correct answer
A.
Step-by-step solution
Let us assume the mass of the water evaporated is , then
On solving we get
