| Question | Answer |
|---|---|
| a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object | temperature |
| an instrument that measures and indicates temperature | thermometer |
| a measure of the kinetic energy of particles in an object | temperature |
| the temperature at which molecular energy is at a minimum | absolute zero |
| the energy transferred between objects that are at different temperatures | heat |
| the transfer of energy as heat through a material | thermal conduction |
| the movement of matter due to the differences in density that are caused by temperature variations | convection |
| any movement of matter that results from differences in density; may be vertical, circular, or cyclical. | convection current |
| the energy that is transferred as electromagnetic waves, such as visible light and infrared waves | radiation |
| the quantity of heat required to raise a unit mass of homogenous material 1K or 1C in a specified way given constant pressure and volume. | specific heat |
| a measure of the randomness or disorder of a system | entropy |
| a machine that transforms heat into mechanical energy | heat engine |
| something that prevents heat to go somewhere | insulator |
| something that allows heat to move | conductor |
| What is the first law of thermodynamics? | the transfer of energy neither creates nor destroys it (energy cant be created or destroyed) |
| what is the second law of thermodynamics ? | energy transferred as heat always moves from objects w/ a higher temperature to objects with a lower temp. |
