Question

A balloonist puts 1.25 X 10⁵ L of air into her hot air balloon at 25C and atmospheric pressure. The air is heated to 200C at constant pressure. What is the volume of air in the balloon at this Temperature?

Answer 1

You have V1 = 1.25x105 L

You have T1 = 25 C (Convert to K by added 273)

You have T2 = 200 C (Convert to K)

You are asked for V2

V1/T1 = V2/T2

Plug and chug and solve for V2
