Question

A balloon is filled with 35.0 L of helium in the morning when the temperature is 20.00 Celsius by noon the temperature has risen to 45.00 Celsius what is the new volume of the balloon

Answer 1

Given
V1 = 35L
T1 = 20.00 C = 293.0 K
V2 = ???
T2 = 45 C = 318 C

Formula
V1/T1 = V2/T2

Sub and Solve
45/293 = x / 318 Cross multiply
45*318 = 293x Divide by 293
45*318/293 = x
14310 / 293 = x
x = 48.84
