In an experiment, a certain amount of steam was allowed to mix with a known mass of cold water whose temperature is known. The change in temperature was noted. From the data obtained, calculate the heat of vaporization of water.
Weight of calorimeter = 100.0g
Specific heat of calorimeter = 0.1cal/g°C
Mass of water = 400.0g
Mass of condensed steam = 27.6g
Temperature of cold water = 5.0°C
Temperature of steam = 100.0°C
Final Temperature of mixture = 45.0°C
