| Question | Answer |
|---|---|
| atom | basic building block of all matter |
| collision Theory | this qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions. A basic principal is that, in order to react, molecules must collide. |
| conduction | this is heat or electrical transfer by contact |
| conservation of energy | this law states that, in any process, energy is neither created nor destroyed. It can only be converted from one form to another. |
| convection | this is heat transfer due to differences in density |
| electrical energy | energy created by the flow of electrons through a conductor. |
| energy | the capacity for doing work. It may be transformed from one form to another. |
| energy transformation | this is the process of changing energy from one form to another. Solar energy is changed into chemical by plants. |
| gas | this is the phase of matter with no fixed shape or volume. |
| heat | the transfer of thermal energy between two bodies which are at different temperatures. The SI unit for this is the Joule. Generally considered the raising of temperature due to thermal energy. |
| heat energy | this is the form of energy that is transferred because of a difference in temperature |
| height | this is the measurement from bottom to top of something. How tall something is. |
| kinetic energy | this is the energy of motion |
| light energy | energy in the form of electromagnetic radiation. Most often associated with a wavelength that is visible to the eye. |
| liquid | this is the phase of matter with no fixed shape but fixed volume |
| mass | this is the measure of the quantity of matter |
| mechanical energy | the energy transferred by a force to a moving object |
| molecular motion | this is the speed at which molecules or atoms move dependent on temperature and state of matter |
| pendulum | this is the body suspended from a fixed support that swings freely back and forth under the influence of gravity |
| potential energy | energy that is stored |
| radiation | heat transfer by electromagnetic waves |
| speed | this is the rate of distance traveled per unit of time, without regard to direction |
| system | this is a group of related parts that move or work together forming a unified whole |
| thermal energy | random kinetic energy possessed by objects in a material at finite temperature. An object that feels hot has a lot of this. |
