That is too hard but u got that cuz i believe in you!!!
Answer:
Heat gain of 142 kJ
Explanation:
We can see that job done by compressing the He gas is negative, it means that the sign convention we are going to use is negative for all the work done by the gas and positive for all the job done to the gas. With that being said, the first law of thermodynamics equation will help us to solve this problem.
Δ
⇒
Δ

Therefore, the gas gained heat by an amount of 142 kJ.
Answer:
14.27 mm
Explanation:
Force = 80 Newton
Pressure exerted = 5 bar = 5×10⁵ Pa
Pressure exerted = Force/Area
Area = Force/Pressure

Area of the cylinder=πd²/4

Hence diameter of cylinder 14.27 mm
