Specific And Latent Heat Worksheet Answers Studying Worksheets

Latent heat and specific heat capacity questions. Use 𝐸 = 𝑚 𝐿 to calculate the amount of energy needed to completely melt or boil a substance and the amount of energy released when a substance freezes or condenses, understand that a substance's internal energy increases but its temperature doesn't increase because it is undergoing a phase. (specific heat capacity of granite is 0.1 cal/g.°c) solution:

Then It Tasks Students With Calculating Heat Using A Table Of Latent Heats For Various Substances Along With.

Specific heat worksheet name (in ink): Because this energy enters or leaves a system during a phase change without causing a temperature change in the system, it is known as latent heat (latent means hidden). Evaporation is much like boiling, only water's heat of vaporization at 35°c is a somewhat larger 24×10^5 j/kg because at lower temperatures more energy is required to break the molecular bonds.
