Calculations involving heat flow involve many often confused terms. Match the term with the correct meaning of these often encountered values in heat calculations. The quantity of heat, in joules or calories, required to raise the temperature of 1 gram of a substance 1^circ mathrm(C) . This is the heat energy involved in the phase change of water and helps drive the water cycle on Earth. The transfer of thermal energy between two bodies which are at different temperatures. The SI unit for this is the Joule. This is the measure of intensity of heat in degrees, reflecting the average kinetic energy of the molecules.

Answer 1

1. Specific Heat 2. Latent Heat 3. Heat Transfer 4. Temperature

Answer 2

## Step1 The first description talks about the amount of heat required to raise the temperature of 1 gram of a substance by 1°C. This is a definition of 'Specific Heat'. Specific Heat is the amount of heat required to raise the temperature of a unit mass of a substance by a certain temperature interval. ## Step2 The second description refers to the heat energy involved in the phase change of water, which is a driving force behind the water cycle on Earth. This is a description of 'Latent Heat'. Latent heat is the energy absorbed or released by a substance during a phase change, which occurs without changing temperature, like during evaporation or condensation. ## Step3 The third description is about the transfer of thermal energy between two bodies that are at different temperatures. The SI unit for this is the Joule. This is a description of 'Heat Transfer'. Heat transfer is the movement of thermal energy from one thing to another thing of different temperature. ## Step4 The fourth description refers to the measure of intensity of heat in degrees, reflecting the average kinetic energy of the molecules. This is a definition of 'Temperature'. Temperature indicates the measure of hotness or coldness measured in terms of degrees. It is a measure of the average kinetic energy of the particles in a system.
