Question

Solve the all parts of given problem:

Problem: A monatomic ideal gas that is initially at a pressure of 1.60 x 10⁵ Pa and with a volume of 8.50 x 10-2 m³ is compressed adiabatically to a volume of 4.10 x 10^-2 m³.

Part I: What is the final pressure?

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

Part III: What is the ratio of the final temperature of the gas to its initial temperature?

Thanks in advance that solve the above problem. Thanks.
