Adiabatic compression and expansion of a gas HD

[fakem99]

means no heat tranfer added or removed, the temp increases and decreases just due to pressue of the piston.

Good work ...

But, entropy changes here, no ?

@FranceOnly

yes the entropy is changing when it is expanding because the disorder increasing,but when it is compressing, the entropy decreasing because the diorder very less. hope you got it.
