What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 11 ∘C , V1= 1400 L ) to a volume of 2800 L ?

Answer 1

Charles Law

T1/V1=T2/V2

if you increase the temperature, the volume of a gas will increase because the molecules have more kinetic energy, pushing against the walls of a container. imagine a balloon

just remember to change your temperature into K (C+273.15)

(284.15/1400L) / (T2/ 2800L)

just looking at the problem you are going to look for an increase in the temperature because the volume is increasing

after solving, you'll get 568.3 K, if your teacher is asking for it in C, just subtract 273.15, which would give you 295.15
