In a vessel containing 9 kg of water at 20°C, 1 kg of steam is introduced at 100°C, which turns into water. Determine the final temperature (in °C) of the water. The heat capacity of the vessel and heat loss are not taken into account. The specific heat capacity of water is 4200 J/(kg*K), the specific heat of vaporization of water is 2.1*106 J/kg.
