An ice block at `0^(@)C` is dropped from height `'h'` above the ground. What should be the value of `'h'` so that it melts completely by the time it reaches the bottom assuming the loss of whole gravitational potential energy is uded as heat by the ice? `[Given: L_(f) = 80 cal//gm]`

10 g of ice at 0^(@)C is mixed with m mass of water at 50^(@)C . What is minimum value of m so that ice melts completely. (L = 80 cal/g and s = 1 cal/ g-.^(@)C )

A piece of ice at 0^(@)C is dropped to the ground from some height. The piece of ice melts completely due to its impact with the ground. Find the height from which the piece was dropped considering that 60% of its energy is converted into heat. (J = 4.2 J cdot cal^(-1))

An ice block at 0^(@)C and of mass m is dropped from height 'h' such that the loss in gravitational potential energy of block is exactly equal to the heat required to just completely melt the ice. Taking latent heat of fusion of ice = 80 cal//gm , acceleration due to gravity = 10 m//s^(2) and mechanical equivalent of heat = 4.2 J//Cal . the value of 'h' is

What is the height from which a piece of ice should be dropped so that it completely melts on hitting the ground ?

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) .

A block of ice at 0^@C is dropped from a height and melts completely on reaching the ground.assuming no loss of energy on the way to ground , Find the height from which it is dropped .

Find out the minimum height from which a piece of ice at 0^(@)C should be dropped so that it melts completely due to its impact with the ground. Assume that half of the energy loss due to the fall is responsible for the fusion of ice. (Latent heat of fusion of ice = 80 cal cdot g^(-1), g = 980 cm cdot s^(-2) , J = 4.2 J cdot cal^(-1))
