It is observed that 1.51 kcal of energy are released when a 21.7 g sample of an unknown liquid condenses. What is the heat of vaporization of the unknown liquid in cal/g?
Heat of vaporization = cal/g
Calculate the amount of heat needed to raise the temperature of 55.0 g of liquid water from 25°C to 99°C. The specific heat of liquid water is 1.00 cal/g °C
Calculate the heat released when 65.5g of water at 55.5 ° C cools to ice at 0.0 ° C. (Given that the specific heat of liquid water is 1.00 calg×°C, and heat of water solidification is 80.0 cal/g.).
