Answer 1

QUESTION # 134265

How many kilojoules of heat will raise the temperature of 1.50 kg of water from 22.00^◦C to 25.00^◦C?

Answer

ΔH= MCΔT

           M= Mass of water

           C = specific heat capacity of water (4.2kJ kg^-k^-)

          ΔT = change of temperature

    = 1.50kg×4.2kJ kg^-k^-(25.00^◦C-22.00^◦C)

    = 18.9kJ
