(4) (a), (b) & (c)​

Answer 1

option four is correct

Explanation:

it is hint solve by yourself

Answer 2

Answer:

From the given Option “4” is correct.

Explanation:

• When a ‘thermodynamic’ process undergoes into a ‘physical change’ in a way where its volume remains constant, then the change which happens is called as isochoric process.

• In the process, the “P and T” changes but the V = constant. Hence ‘Gay-lussac’s law’ is obeyed in the above process.

• When a ‘thermodynamic’ process undergoes into a ‘physical change’ in a way where its pressure remains constant, then the change which happens is called as isobaric process.
• In the process V and T changes but P remains constant. Hence ‘Charle’s law’ is obeyed in the above process.

• Work done by the system will be zero in adiabatic free expansion because it is a irreversible.
