Check all the correct statements.

The internal energy of an ideal gas (those that obey PV = nRT)depends only the temperature of the system.
The internal energy of any gas depends only the temperature ofthe system.
The heat capacity of an ideal gas does not depend on whatmolecules the gas is made of.
At constant temperature, the internal energy of a real gasincreases with increasing pressure because molecules are closertogether. We assume that the conditions are such that attractionsdominate over repulsions (i.e. the pressure values are not toohigh)
At constant temperature, the internal energy of a real gasdecreases with increasing pressure because molecules are closertogether. We assume that the conditions are such that attractionsdominate over repulsions (i.e. the pressure values are not toohigh)
A cyclic path (initial state = final state) always results in∆U = 0
∆U = 0 for any process that does not result in a change intemperature.
  ΔU= qv only for amonoatomic ideal gas
