Internal latent heat is defined as

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

One gram of ice at 0^(@)C is added to 5 gram of water at 10^(@)C . If the latent heat of ice be 80 cal/g, then the final temperature of the mixture is -

A coil of enamelled copper wire of resistance 50Omega is embedded in a block of ice and a potential difference of 210V applied across it. Calculate the rate of which ice melts. Latent heat of ice is 80 cal per gram.

A coil of enamelled copper wire of resistance 50Omega is embedded in a block of ice and a potential difference of 210V applied across it. Calculate the rate of which ice melts. Latent heat of ice is 80 cal per gram.

From what height must a block of ice be dropped in order that it may melt completely. It is assumed that the whole of energy is retained by ice. Given that latent heat of ice = 80 cal g^(-1) .

The water of mass 75 g at 100^(@)C is added to ice of mass 20 g at -15^(@)C . What is the resulting temperature. Latent heat of ice = 80 cal//g and specific heat of ice = 0.5 .

1 g of steam at 100^@C and an equal mass of ice at 0^@C are mixed. The temperature of the mixture in steady state will be (latent heat of steam =540 cal//g , latent heat of ice =80 cal//g ,specific heat of water =1 cal//g^@C )
