From what minimum height a block of ice has to be dropped in order that `0.5%` of ice melts on hitting the ground ?

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 piece of ice at 0^@C is dropped into water at 0^@C . Then ice will

What is the melting point of ice?

Find out the minimum height from which a piece of ice should be dropped to the ground so that it melts completely. Assume that 20% of energy is lost. J = 4.2 xx 10^(7) erg cdot cal^(-1) and latent heat of fusion of ice = 80 cal cdot g^(-1) .

From what height must a block of ice fall to just melt by the impact assuming that half of the heat generated is absorbed by ice? ( J=4.2 joules per calories and L=80 kilocalories per kg)

Ice cubes at 0^(@)C each of mass 200 g are dropped one after the other into 2 kg water at 30^(@)C in such a awayy that after the first one melts completely, the second one is dropped. If the heat energy required to melt 1 g of ice is 80 cal, determine the maximum number of ice ice cubes that can be dropped into the water such that no ice is left in the water without melting.

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))
