In a cold storage, ice melts at the rate of `2 kg//h` when the external temperature is `20^(@)C`. Find the minimum power output of the motor used to drive the refrigerator which just prevents the ice from melting. Latent heat of fusion of `ice = 80 cal//g`

The ice in a cold storage melts at 3kg//hr . Find the minimum power output of the motor used to drive the refrigerator which prevents the ice from melting if the surrounding temperature is 27^@C .

Ice melts at the rate of 5 kg per hour in a cold storage when the temperature outside is 300 K. Calculate the minimum power of the motor is to be used to drive a refrigerator to just prevent the melting of ice. Specific latent heat of usion of ice =3.3 xx 10 ^(5) J kg ^(-1) .[E.Q]

What power is gained by a man when he eats 100 g ice in one minute ? Latent heat of fusion of ice is 80 cal/gm.

How many calories of heat will be absorbed when 2kg of ice at 0⁰C melts ? (Specific latent heat of fusion of ice = 80 cal/g)

Calculate the amount of heat absorbed by 100 g of ice to change into water of 30^@ C.(Latent heat of fusion of ice is 80 cal//g )

How many calories of heat will be absorbed when 2kg of ice at 0^(@)C melts ? ( Specific latent heat of fusion of ice = 80 cal //g )

Calculate the amount of heat required to convert 80 g of ice at 0⁰C into water at the same temperature . (Specific latent heat of fusion of ice = 80 cal/g)

Find the heat required to convert 20 g of ice at 0⁰C into water at the same temperature . (Specific latent heat of fusion of ice = 80 cal/g)

Calculate the heat gained by 50 g of ice at 0^(@)C to change into water of the same temperature. (Latent heat of fusion of ice is 80 cal/g)
