Question

PLEASE HELP!!!

A student decreases the temperature of a 397 cm3 balloon from 515 K to
220 K.
Assuming constant pressure, what should the new volume of the balloon be?
Round your answer to one decimal place.

Answer 1

P V = N R T ideal gas equation

V2 / V1 = T2 / T1 dividing equations

V2 = 397 cm^3 * (220 / 515) = 170 cm^3
