Heal releases by 1 kg steam at 150°C if it is converted into 1 kg water at 50°C. 200 g water is filled in a calorimetry of negligible heat capacity. It is heated till its temperature is increase by 20°С. Find the heat supplied to the water. A hullat of mass 5 qm is moving with speed 400 m/s strike a target Then calculate rise of temperature of water.
