Thermal Energy |
The sum of kinetic and potential energy of all the particles in an object |
|
|
Specific Heat |
The amount of heat needed to raise the temp of a 1kg of that substance by 1 degree celsius |
|
|
Conduction |
When the particles within a substance or between two substances bump into each other and transfer kinetic energy |
|
|
Convection |
The transfer of thermal energy in a fluid by the movement of warmer and cooler fluids from one place to another |
|
|
Thermal insulator |
A material in which heat flows slowly |
|
|
Solar Collectors |
Absorb radiant energy from the sun |
|
|
Thermodynamics |
The study of the relationship among thermal energy, heat, and work |
|
|
First law of thermodynamics |
The increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system |
|
|
Second law of thermodynamics |
It is impossible for the heat to flow from a cool object to a warmer object unless work is done. |
|
|
Heat engine |
A device that changes thermal energy into mechanical energy |
|
|
Internal combustion engine |
The fuel burns inside the engine in chambers, or cylinders. |
|
|
Solar collectors |
The study of the relationship among thermal energy, heat, and work |
