Identify the characteristics of an adiabatic process in a monoatomic gas. (A) Internal energy is constant. (B) Work done in the process is equal to the change in internal energy. (C) The product of temperature and volume is a constant. (D) The product of pressure and volume is a constant. (E) The work done to change the temperature from T1 to T2 is proportional to (T2 - T1). Choose the correct answer from the options given below: (1) (A), (C), (E) only (2) (B), (E) only (3) (A), (D) only (4) (B), (D) only

1. (A), (C), (E) only
2. (B), (E) only
3. (A), (D), (E) only
4. (B), (D) only

Correct answer: (B), (E) only

Solution

In an adiabatic process, there is no heat exchange with the surroundings, so the work done is equal to the change in internal energy, which is described by option (B). Additionally, the work done to change the temperature is proportional to the temperature difference (T2 - T1), as stated in option (E), making both options correct.
