A container of gas at 3.90atm pressure and 136 ∘C is compressed at constant temperature until the volume is halved. It is then further compressed at constant pressure until the volume is halved again.
What is the final temperature of the gas?
The Attempt at a Solution
seems like a very easy question, but I'm doing Mastering Physics and it is saying I am wrong.
the volume is being halved and the pressure remains constant, so shouldn't the temperature just be halved also?
I got 68 degrees celsius as my answer, but Mastering Physics says it is wrong and I should check my signs but that shouldn't be an issue.
