Question 15

A sample of an ideal gas inside a pneumatic actuator is initially at a temperature of 15 ∘C15\ ^\circ\text{C}15 ∘C. During a rapid stroke, the gas is compressed to one-fifth of its original volume, causing its absolute pressure to increase by a factor of 7.57.57.5.

What is the new temperature of the gas?
