A sample of gas in a balloon has an initial temperature of 11 ∘C and a volume of 1400 L . If the temperature changes to 70 ∘C , whats the volume of V2 gas?

Answer 1

T1 = initial temperature in Kelvin = 11 + 273 = 284K

V1 = initial volume = 1400 L

T2 = final temperature in Kelvin = 70ºC +273 = 343K

V2 = ?

V1/T1 = V2/T2 (Charles Law)

V2 = V1T2 / T1

V2 = final volume = (1400 L)(343K) / 284K = 1691 L
