Heat and Energy
| Question | Answer |
|---|---|
| Conduction | When heat is transferred through a material through atomic vibrations or contact. |
| Convection | When heat is transferred because of changes in density (hot material rises, cool material sinks). |
| Radiation | When heat is transferred without a medium. The heat moves in electromagnetic wave form. |
| Thermometer | A tool used to measure the kinetic energy of a material. |
| Temperature | The amount of kinetic energy in a material. |
| Thermal Expansion | When atoms move away causing temperature to increase. |
| Solid | A type of matter that has a definite shape. |
| Liquid | A type of matter that has no definite shape. Takes the shape of the container. Atoms are barely bonded. |
| Gas | A type of matter that has no definite shape and atoms are not bonded. |
| Density | A measure of mass at a set of volume |
| Melting | When a solid turns into a liquid. |
| Freezing | When a liquid turns into a solid. |
| Condensation | When a gas turns into a liquid. |
| Evaporation | When a liquid turns into a gas. |
| Electromagnetic Spectrum | The 7 kinds of radiation from radio to gamma waves. |
| Heat | When energy moves from one place to another. |
| Endothermic | When energy is taken in during a chemical reaction |
| Exothermic | When energy is released during a chemical reaction |
