ch16 Flashcards
1
Q
internal energy
A
the sum of potential energies and kinetic energies of all the molecules owing to their random motion
2
Q
internal energy that is determined by the state of the system
A
the sum of a random distribution of kinetic and potential energies associated with the molecules of the system
3
Q
Thermal energy and temperature
A
A rise in temperature of an object is related to an increase in the internal energy of the object.
4
Q
work equation
A
w=pΔV
5
Q
Explain why an increase in internal energy of an ideal gas is directly related to a rise in temperature of the gas.
A
(random) kinetic energy increases with temperature
no potential energy (so increase in temperature increases internal energy)
