Why Things Move
heat
thermal equilibrium
thermal energy
conduction
convection
- Heat (\(Q\)) measured in J
kelvin
absolute temperature scale
- Temperature (\(T\)) measured in K
When a physics equation contains a \(T\), use Kelvin.
When a physics equation contains a \(\Delta T\), you may use either Kelvin or Celsius.
heat capacity
specific heat
thermal reservoir
thermal energy
- heat capacity (\(C\)) measured in J/K
- specific heat (\(c\)) measured in J/kg/K
- Thermal Energy (\(E_{th}\)) measured in J
\(C=mc\)
\(E_{th}=CT=mcT\)
