Question
A fixed quantity of air at T1 = 57oC and P1 = 222 kPa is heated at constant temperature in a piston-cylinder assembly until its volume has increased by 37%. Determine the final pressure P2 (kPa) of the air. correct answer 162.0

AnswerShow Work EQUATIONS EQUATIONS Please !!! explain where the numbers come from or else i wont understand if you dont show where they came from... dont just post numbers and get answers if u get a number from a table or something just say what the number is clearly !!!!!!!!
Explanation / Answer
For constant temperature process, P1*V1 = P2*V2
We have V2 = V1 + 0.37*V1 = 1.37*V1
So, 222*V1 = P2*(1.37*V1)
P2 = 222/1.37 = 162.04 kPa
