6151 .nll '3' C} X Aiana Ray... IQ 1 / E Name Date Per. Specic Heat and Latent Heat The specic heat of a substance is the amount of energy needed to raise the temperature of that substance one Celsius degree. The latent heat, or heat of fusion and heat of vaporization is the amount of heat energy needed to change the state of a substance. These quantities can be summed to calculate the total heat needed to take a substance from one temperature and state to another temperature and state. Using the phase change of water graph below, label each region with the correct formula and the constant that corresponds to each section. mpeum "'" 1'0) '1 not unearned Remember that the graph above is like a roadmap that will get you from one place to another. For each problem that follows, nd the original spot that it begins and then the spt where it ends. Each section of the graph corresponds to a different quantity. If the section is horizontal, you will use Q=mL. If the section has nonzero, positive slope, you will use ch T and the c goes with the phase of matter for the substance. 1. What is the heat energy needed to change 35 g of water at 8.0 \"C to 34.0 \"C? 2. What is the amount of heat necessary to melt 34 kg of ice at 0.0 \"C to water at 0.0 \"C? Name Date Per. Specic Heat and Latcnt Heat 3. What is the heat energy needed to change 43.2 g of ice from -15.0 "C to water at 0.0 \"C? 4. What is the total heat energy needed to change 150 g of ice from -15.0 \"C to water at 80.0 8C? 4.

For each problem that follows, find the original spot that it begins and then the spt where it ends. Each section of the graph corresponds to a different quantity. If the section is horizontal, you will use Q=mL. If the section has nonzero, positive slope, you will use Qmc T and the c goes with the phase of matter for the substance. 1.
