Activity: Calculate how much water at a temperature of 80°C needs to be added if the final temperature of the mixture is to be 30°C? The specific heat kJ of water is 4.2 kg x °C The amount of heat that needs to be provided to the water at a temperature of 20°C to heat it to 30°C is equal to: kJ. So you have to add 21 kg of water. 20° C 0.5 kg
