Question

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

Answer 1

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
