How much steam at `100^(0)C` is to be passed into water of mass `100g` at `20^(0)C` to raise its temperature by `5^(0)C`? (latent heat of steam is `540cal/gm`)

How much steam at 100^(@) C is to be passed into water of mass 100g at 20^(@)c to raise its temperature by 5^(@)C ? (Latent heat of steam is 540 cal /g and specific heat of water is 1 cal // g^(@)C )

20g of steam at 100^(@) C is passed into 100g of ice at 0^(0) C. Find the resultant temperature if specific latent heat of steam is 540 callg., specific latent heat of ice is 80 cal/g and specific heat of water is 1 cal/ g^(0) C .

50 g of steam at 100^@ C is passed into 250 g of at 0^@ C . Find the resultant temperature (if latent heat of steam is 540 cal//g , latent heat of ice is 80 cal//g and specific heat of water is 1 cal//g -.^@ C ).
