`1 kg` of iron (specific heat `120 Cal Kg^(-1) C^(-1)`) is heated by `1000^(@)C`. The increases in its mass is

Mass of object is 200g and its specific heat is "0.09 cal. g"^(-1).^(@)C^(-1) . How much that heat is required to increase its temperature from 20^(@)C to 90^(@)C ?

In the temperature range 0 to 1000 ^(@)C the average specific heat of copper is 378J kg ^(-1) K ^(-1). If 2 kg of copper is heated from 0 to 1000^(@)C by how much does its mass increase ?

500 kg of water is heated from 20^(@) to 100^(@) C . Calculate the increase in the mass of water.Given specific heat of water =4.2 xx 10^(3) J kg ^(-1) .^(@)C^(-1) .

500 kg of water is heated from 20^(@) to 100^(@) C . Calculate the increase in the mass of water.Given specific heat of water =4.2 xx 10^(3) J kg ^(-1) .^(@)C^(-1) .

A 10 kg iron bar (specific heat 0.11 cal/g ""^(@) C) at 80 ""^(@) C is placed on a block of ice. How much ice melts?

A iron ball of mass 0.2 kg is heated to 100^(@)C and put into a block of ice at 0^(@)C .25 g of ice melts , then specific heat of iron ( in cal kg^(-10) C^(-1) ) is [ Latent heat of fusion of ice = 80 cal g^(-1) ]
