Question

A gaseous system changes from state A(P1,V1,T1) to B(P2,V2,T2), B to C (P3,V3T3) and finally from C to A. The whole process may be called

A. Cyclic process
B. Reversible process
C. Isobaric process
D. Spontaneous process

Answer 1

A gaseous system that changes from state A(P1,V1,T1) to B(P2,V2,T2), B to C (P3,V3T3), and finally from C to A is undergoing a cyclic process.

Step-by-step explanation:

A gaseous system that changes from state A(P1,V1,T1) to B(P2,V2,T2), B to C (P3,V3T3), and finally from C to A is undergoing a cyclic process. A cyclic process is one in which the state of the system at the end is the same as the state at the beginning. In this case, the system returns to its original state after going through the sequence of changes.

The other options can be ruled out:

• A reversible process is one that can be made to retrace its path by differential changes in the environment, but it is not implied that the process described is reversible.
• An isobaric process is one in which the system's pressure does not change, but the given states involve changes in pressure.
• A spontaneous process occurs naturally without the need for external intervention, but the given states involve changes that are not necessarily spontaneous.
