Question

An ideal gas in the amount of 1 moles first expands isobarrically and then cools isochorically. During the entire process, an amount of heat 4800 J is transferred to the gas. The initial and final gas temperatures are the same and equal to 285 K. Find the ratio of the final gas volume to its initial volume.

Answer 1

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

The temperature remains unchanged therefore 

Uf=Ui

Also, ΔQ=ΔW.

In the first step which is isochoric, ΔW=0.

In second step, pressure = nP. Volume is increased from V to nV.

∴W=P/n(nV−V)

= PV (n−1/n)
