An ice box used for keeping eatables cool has a total wall area of `1m^2` and a wall thichness of 5.0 cm. The thermal cunductivity of the ice box is `K=0.01 J//m^@C`. It is filled with large amount of ice at `0^@C` along with eatables on a dfay when the temperature is `30^@C` The latent heat of fusion of ice is `334xx10^3 J//kg`. The amount of ice melted in one day is ( 1 day`=86,000s`)

What is meant by saying that the latent heat of fusion of ice is 3.34 xx 10^(5)J//kg ?

Latent heat of fusion / melting of ice:

A 2 kg copper block is heated to 500^@C and then it is placed on a large block of ice at 0^@C . If the specific heat capacity of copper is 400 "J/kg/"^@C and latent heat of fusion of water is 3.5xx 10^5 J/kg. The amount of ice that can melt is :

Calculate the amount of heat energy to be supplied to convert 2 kg of ice at 0^@C completely into water at 0^@C if latent heat of fusion for ice is 80 cal/g.

Calculate the amount of heat energy to be supplied to convert 4 kg of ice at 0^@C completely into water at 0^@C if latent heat of fusion for ice is 80 cal/g.

At 0^(2)C , if enthalpy of fusion of ice is 1365 kcal/mol. The molar entropy, change for melting of ice at 0^(@)C is

The amount of heat required to raise the temperature of 75 kg of ice at 0°C to water at 10°C is (latent heat of fusion of ice is 80 cal/g, specific heat of water is 1 cal/g °C)

M g of ice at 0^@C is to be converted to water at 0^@C . If L is the latent heat of fusion of ice, the quantity of heat required for the above operation would be
