Question | Answer |
---|---|
Insulator | Substances that do not conduct well. Ex.: Glass, wood, plastic, rubber, and air. |
Conductor | Substances that transfer heat well. Ex.: metals such as iron, aluminum, and copper. |
Thermometer | Measures how hot or cold something is. |
Thermal energy | Basically means the same thing as heat. The total energy of the vibrating particles in an object. |
Freeze | This occurs when a liquid changes into a solid. |
Melt | This occurs when a solid changes into a liquid. |
Vaporization | This occurs when a liquid changes into a gas. |
Condensation | This occurs when a gas changes into a liquid. |
Matter | Anything that has mass and takes up space. |
Heat | A transfer of thermal energy from A WARMER OBJECT TO A COOLER OBJECT. Heat is caused by the internal motion of the molecules of matter. It depends on the total kinetic energy of the particles. |
Radiation | Heat energy is transferred through empty space. Ex. sun |
Conduction | Heat is transferred through a substance by direct contact of the molecules. It takes place best in a solid. |
Convection | The heated portion rises and the cooler air sinks. This creates a current. It takes place best in liquids or gasses. |
The Three Types of Heat Transfer | Conduction, Convection, Radiation. |
