... It takes 4186J of heat to raise the temperature of 1kg of water by 1°C The heat required for a 1°C increase varies from one substance to another, e.g. it takes only 129J of heat to increase the temperature of lead by 1°C The heat required for a given increase in temperature is given by the heat capa ...
