4. Mass m of gas X is at temperature t1 C and pressure P1Pa. Find Q,∆,A for:
-isothermal expansion (compression) up to volume V2
- isochoric increase (decrease) in pressure up to Р2
- isobaric expansion (compression) up to volume V2
-adiabatic expansion (compression) up to volume V2
- adiabatic increase (decrease) in pressure up to Р2
Consider the gas to be ideal.
