In an experiment on latent heat of vaporization of water, steam enters a calorimeter for a short period of time. The mass and the temperature of water increases in the calorimeter. Data is given below: Before experiment 160g at 20C . After experiment 166g at 37.7C, Mass of water, g Temperature of water, C Use approximate heat balance to calculate the latent heat of vaporization of water in J/gC.
