A student decreases the temperature of a 556 cm^3 balloon from 278 K to 231 K. Assuming constant pressure, what should the new volume of the balloon be

Given:

A student decreases the temperature of a 556 cm^3 balloon from 278 K to 231 K at constant pressure

Required:

new volume of the balloon

Solution:

Apply Boyle's law

V1/T1 = V2/T2

(556 cm3) / (278K) = V2 / (231 K)

V2 = 462 cm3
