Question

A mixture of krypton and argon gas is compressed from a volume of

85.0L

to a volume of

37.0L

, while the pressure is held constant at

51.0atm

. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits. 

Expert Solution
Step 1: Sign assigning to the work done!

Answer:

In thermodyanimcs, expansion work is always considered as negative and compression work is always positive considered as positive.
