1.
The internal energy of a solid includes
only the bulk kinetic energy
random kinetic energy only
random kinetic energy and intermolecular potential energy
only potential energy
2.
The internal energy of an ideal gas depends only on
temperature
density
pressure
volume
3.
During melting at constant temperature, internal energy
becomes zero
is constant
decreases
increases
4.
For 1.0 mol of an ideal monatomic gas at 400 K, U is about
0.5 kJ
5.0 kJ
2.5 kJ
1.2 kJ
5.
Rubbing hands together warms them because
the temperature difference grows
the mass changes
heat flows in from the air
work done increases the internal energy
6.
Which statement is correct?
Heat is the transfer of energy due to temperature difference
Internal energy is bulk kinetic energy
Temperature equals internal energy
An object contains heat
