4. A tank of sunflower oil is heated from 20 °C to 80 °C. The volume of the oil is 2 m³ and the density of oil is 1100 kg/m³. The specific heat of oil is 2.1311 (kJ/(kg ° C). 1035 kg of water is used to heat the oil. The specific heat of hot water is 4.18 (kJ/(kg ° C). If the temperature of incoming hot water is 90 °C, what will be the temperature of exit water?
