Question

Compute all parts of following problem given below:

Problem: A monatomic ideal gas that is initially at a pressure of 1.41×10⁵Pa and with a volume of 7.50×10² m³ is compressed adiabatically to a volume of 4.50×10²m³.

Part I: what is the final pressure?

Part II: How much work is done by the gas during the compression?

Any help I can get on this problem is greatly appreciated! I'm not too familiar with this problem.
