JEE Main 2025 Physics question
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 to is proportional to . Choose the correct answer from the options given below :
Answer: (2)
Solution
For adiabatic process Q=0, so ΔU=-W, and W is proportional to temperature change; hence B and E are correct.
