Introduction:
Many folks have a great deal of difficulty dinguishing between heat and temperature. In this unit you will learn about the characteristics of each. Briefly, heat is an energy transfer mechanism, whereas temperature relates more closely with the kinetic energy (think motion) of a system of particles. We will examine how increasing the temperature affects the expansion of some material, different energy transfer properties, and how objects arrive at thermal equilibrium. |
| For your test you should be able to: |
| 1) Define the following vocabulary words: |
| Kinetic Energy |
Absolute Zero |
Translational Motion |
Thermometer |
| Fahrenheit |
Celsius |
Thermal Expansion |
Kinetic Theory |
| Kelvin |
Calorie |
Conduction |
Convection |
| Radiation |
Stefan-Boltzman Radiation |
Specific Heat |
Heat Capacity |
| Phase Change |
Equilibrium |
Fusion |
Vaporization |
| 2) Distinguish between heat and temperature. |
| 3) Determine the length by which an object will expand or contract given a certain change in temperature. |
| 4) Compute the equilibrium temperature of a mixture. |
| 5) Explain how the value of absolute zero was determined. |
| 6) Distinguish among and describe conduction, convection, and radiation. |
