When a monoatomic ideal gas undergoes an isothermal change:
(A) The number of degrees of freedom of the molecules changes
(B) The temperature changes
(C) There is no change of internal energy
(D) There is no exchange of heat with the surroundings
For a certain gas the ratio of specific heats is given to be = 1.5. For this gas:
(A) Cv = 3R
(B) Cp = 3R
(C) Cv = 5R
(D) Cp = 5R
In an isothermal expansion:
(A) Internal energy of the gas increases
(B) Internal energy of the gas decreases
(C) internal energy remains unchanged
(D) Average kinetic energy of the gas molecules decreases
In an adiabatic process, the is no:
(A) Change in temperature
(B) exchange of heat
(C) Change in internal energy
(D) work done
During which process the change in the internal energy of the system is equal in magnitude to the work done by system :
(A) Isobaric
(B) isochoric
(C) Adiabatic
(D) isothermal process
We all know that Cp> Cv. What is also true for these molar specific heats (CP, CV)?
(A) ΔQP > ΔQv
(B) ΔUP = ΔUv
(C) ΔTP = ΔTV
(D) All of these
When the state of gas change without change the temperature, the gas is said to undergo:
(A) Isothermal process
(B) Isochoric process
(C) Adiabatic process
(D) Isobaric process
