Jack is conducting experiments to test whether ambient temperature affects the rate of water evaporation. He used anhydrous cobalt chloride paper, water, filament light bulbs and white tiles. Q: What is the use of filament light bulbs in the experiments?​

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
