How much heat is required to raise the temperature of 90 g of water from 30^(@)C to 100^(@)C ? [Molar heat capacity of water at constant pressure =75.3J*mol^(-1)*K^(-1) ]

Amount of heat required to raise the temperature of 1 kg of water by 1^@C is

To rise temperature of 30 gm water from 20^@C to 50^@C how much heat is required?

The amount of heat energy required to raise the temperature of 1g of water b 1^@C is called

The mass of a copper steam boiler is 200 kg. It contains 100 kg of water at 25^(@)C.7xx10^(6) cal of heat is produced by burning 1 kg of coal and only 3% of it is absorbed by the boiler to heat water. How much coal is to be burnt to raise the temperature of the water in the boiler to its boiling point? Specific heat of copper ="0.09 cal.g"^(-1).^(@)C^(-1) .

What is the heat needed (in J) to increase the temperature of 5 g water by 1^@C ?
