A nuclear power plant generates 500 MW of waste heat that must be carried away by water pumped from a lake. If the water temperature is to rise by `10^@C`, what is the required flow rate in `kg//s`?

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?

Heat required to increases the temperature of 1kg water by 20^(@)C

Heat required to increases the temperature of 1kg water by 20^(@)C

The quantity of heat required to raise the temperature of 2000 g of water from 10^@C to 50^@C is

Water is filled in a vessel which is kept in a room at a temperature of 20^(@)C . The temperature of the water is slowly increased. When the temperature of water is 40^(@)C , it loses heat at the rate of 10cal/s. What will be the rate of loss of heat when the temperature of water is 80^(@)C ?
