# Temperature Change After Gas Compression

**Question**

A cylinder fitted with a moveable piston contains 2L of oxygen at 25°C and 3 bar. The piston is pushed to compress the gas to a pressure of 6 bar.

a. Write and simplify the energy balance for this system. (Do not assume the process is isothermal.)

b. Now assume the process is isothermal. The compression work done on the gas is 4.6L•bar.

Assume the gas is ideal (?? is a function only of T). How much heat is transferred to or from the system (be careful of the sign of Q)? Express Q in common heat units.

c. Now assume the process is adiabatic. Is the final system temperature greater or less than 25°C. (?? increases as T increases.)**Summary**

The question belongs to Chemical Engineering and the question is about finding temperature change after compression a gas from 3 bar to 6 bar. The solution has all the calculations for this problem.

JaneteHello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
