How many times has the gas volume changed during isobaric cooling from 575 to 230 K?

To find the change in the volume of the indicated gas during isobaric cooling, we will use the formula: n = Vн / Vк = Тн / Тк.

Variables: Тн – temperature of the specified gas before cooling (Тн = 575 К); Тк – temperature after cooling (Тк = 230 К).

Let’s calculate: n = Tn / Tk = 575/230 = 2.5 p.

Answer: After isobaric cooling, the volume of this gas decreased by 2.5 times.
