Aballoon originally had a volume of 4.39 l at 44°c and a pressure of 729 torr. to what temperature must the balloon be cooled to reduce its volume to 3.78 l if the pressure is constant

Explanation:

p*V/T = constant , but p = constant => V/T = constant

Note: T must be in Kelvin.

V1/T1 = V2/T2

T2 = (V2/V1)* T1

T2 = (3.78/4.39)* (44+273) = 272.95 ≈ 273 K = 0° C

The temperature must be 0° C
