Science Vocab Ch. 1
Using Energy and Heat; Lessons 1 - 3
| Term | Definition |
|---|---|
| Energy | Scientists define ... as the ability to cause change. |
| Potential Energy | ... is stored energy due to the interaction between objects or particles. |
| Chemical Energy | ... is the energy stored in and released from the bonds between atoms. |
| Nuclear Energy | The energy stored in and released from the nucleus of an atom is called ... |
| Kinetic Energy | If so, you have ...-energy due to motion. |
| Electric Energy | The energy in an electric current is ... |
| Mechanical Energy | The sum of the potential energy and the kinetic energy in a system is ... |
| Thermal Energy | An object's ... is the sum of the kinetic energy and potential energy of the particles that make up the object. |
| Wave | A ... is a disturbance that transfers energy from one place to another without transferring matter. |
| Sound Energy | ... is energy carried by sound waves. |
| Radiant Energy | The energy carried by electromagnetic waves is ... |
| Law of Conservation of Energy | The ... says that energy can be transformed from one form to another, but it cannot be created or destroyed. |
| Energy Transfer | When energy moves from one object to another without changing form, an ... occurs. |
| Energy Transformation | When one form of energy is converted to another form of energy, an ... occurs. |
| Work | To a scientist, ... is the transfer of energy that occurs when a force makes an object move in the direction of the force. Work is only being done while the force is acting on the object. |
| Open System | An ..., such as a car engine, is a system that exchanges matter or energy with the environment. |
| Closed System | A ... is a system that does not exchange matter or energy with the environment. |
| Renewable Energy Resource | A ... is an energy resource that is replaced as fast as, or faster than, it is used. |
| Nonrenewable Energy Resource | Fossil fuels and nuclear energy are ...-an energy resource that is available in limited amounts or that is used faster that it can be replaced in nature. |
| Temperature | The measure of the average kinetic energy of the particles in a material is ... |
| Heat | The movement of thermal energy from a region of higher temperature to a region of lower temperature is called ... |
| Conduction | ... is the transfer of thermal energy by collisions between particles in matter. |
| Radiation | The thermal energy you feel is from ...-the transfer of thermal energy by electromagnetic waves. |
| Convection | The transfer of thermal energy by the movement of the particles from one part of a material to another is ... |
| Vaporization | ... is the change of state from a liquid to a gas. |
| Thermal Conductor | The metal that makes up the pan is a ..., a material in which thermal energy moves quickly. |
| Thermal Insulator | The material that makes up the pan's handles is a ..., a material in which thermal energy moves slowly. |
