- Thermal Physics
- absolute temperature: the temperature at which the pressure of an ideal gas becomes 0
- average kinetic energy of molecules increases? Temperature increases
- absolute temperature: the temperature at which the pressure of an ideal gas becomes 0
- effect transferred heat energy has on temperature depends on:
- amount of heat energy transferred
- E=MCAT in JKg-1K-1
- mass of the object
- E=MCAT in JKg-1K-1
- specific heat capacity of material
- amount of heat energy transferred
- internal energy: the total random distribution of kinetic and potential energy is a collection of particles
- this internal energy is randomly distributed across all molecules according the the maxwell-boltzmann distribution
- all have same mass, Ek dependent on speed [Ek=1/2mv2]
- maxwell-boltzmann distribution shows that: * no molecules have 0 energy *only afew have high energies * There is no maximum value for energy
- two interesting speeds
- most probable
- root-mean-square speed
- two interesting speeds
- maxwell-boltzmann distribution shows that: * no molecules have 0 energy *only afew have high energies * There is no maximum value for energy
- Each graph = one specific temperature
- all have same mass, Ek dependent on speed [Ek=1/2mv2]
- this internal energy is randomly distributed across all molecules according the the maxwell-boltzmann distribution
