A closely thermally insulated vessel contains 100 g of water at `0^@C`. If the air from this vessel is rapidly pumped out, intensive evaporation will produce cooling and as a result of this, water freeze. How much ice will be formed by this method? If latent heat of fusion is `80 cal//g` and of evaporation `560 cal//g` .
[ Hint If `m` gram ice is formed, `mL_(f)=(100-m)l_(v)`]

To solve the problem, we need to determine how much ice will be formed when air is pumped out of a thermally insulated vessel containing 100 g of water at 0°C. The latent heat of fusion (L_f) is 80 cal/g and the latent heat of evaporation (L_v) is 560 cal/g. ### Step-by-Step Solution: 1. **Define Variables:** - Let \( m_1 \) be the mass of ice formed (in grams). - The initial mass of water \( m = 100 \) g. ...
