| Term | Definition |
|
Absolute Zero |
The temperature at which a substance has no kinetic energy to give up. 0 K |
|
Celsius Scale |
A temperature scale in which the number number 0 is assigned to temperature at which water freezes, and the number 100 is assigned to the temperature at which water boils |
|
Fahrenheit Scale |
The Temp scale commonly used in U.S. 32 corresponds to water freezing; 212 to boiling point of water |
|
Kelvin |
SI unit of temperature; indicates number of units above absolute zero |
|
Kelvin Scale |
Temp scale calibrated in terms of energy itself. |
|
Temperature |
The property of a material that tells how warm or cold it is with respect to some standard. |
|
Heat |
The energy that is transferred from one material to another because of temperature difference between the materials. Once the energy is absorbed by matter, it is internal energy. |
|
Thermal Contact |
The state of two or more ojects that is possible for heat to flow from one to another |
|
Thermal Equilibrium |
The state of two or more objects or substances in thermal contact when they have reached a common temperature |
|
Specific Heat |
The quantity of heat required to raise the temperature of a unit mass of a substance by one degree |
|
Internal Energy |
The total energy inside of a substance |
|
calorie |
Unit of heat; one calorie is amoutn needed to raise temp of 1g of water 1 degree celsius. |
|
Kilocalorie |
A unit of heat; one kilocalorie equals 1000 calories. Raises 1kg of water 1 degree celsius. |
|
Bimetallic Strip |
Two strips of different metals, such as one brass and one of iron, that are welded or riveted together; Because substances expand at different rates, when heated or cooled they bend in different directions. |
|
Thermostat |
A type of valve or switch that responds to change in temperature and that is used to control the temperature of something. |
