What is the latent heat of the fusion of ice?

What is latent heat?

In SI unit the latent heat of fusion of ice is :

The initial temperature of a lead bullet (specific heat 0.02 cal cdot g^(-1) cdot^(@)C^(-1)) of mass 50 g is 30^(@)C . It is projected upwards with a velocity of 840 m cdot s^(-1) . When the bullet falls down to the point of projection, it hits a block of ice. If the temperature of the ice will be transformed into water? Assume that the entire energy is consumed by the ice. The latent heat of fusion of ice = 80 cal cdot g^(-1) .

What is latent heat of fusion?

22320 cal of heat is supplied to 100 g of ice at 0^(@)C . If the latent heat of fusion of ice is 80cal g^(-1) and latent heat of vaporization of water is 540cal g^(-1) , the final amount of water thus obtained and its temperature respectively are

What is latent heat of a substance?

A block of ice having mass 6 kg is pulled 50 m horizontally over a surface of ice. The temperature of both the ice is 0^(@)C , coefficient of friction between the surfaces of ice is 0.03 and latent heat of fusion of ice is 80 cal cdot g^(-1) . Calculate the amount of ice that melts.

Two pieces of ice, of equal mass and moving towards each other with the same velocity, collide head on and are vaporised due to this collision. Find out the minimum initial velocity of the pieces of ice. Given, initial temperature, specific heat and latent heat of fusion of ice are -12^(@)C, 0.5 cal cdot g^(-1) cdot^(@)C^(-1) and 80cal cdot^(@)g^(-1) respectively, latent heat of steam is 540 cal cdot g^(-1) .
