Slide 17: practice slide #4
at 283k, the gas in a cylinder has a volume of 0.250 l. the gas is allowed to
expand to 0.285 l. what must the final temperature be for the pressure to remain
constant?

T₂ = 322.62 k

Explanation:

Given data:

Initial volume = 0.250 L

Initial temperature =  283 K

Final volume = 0.285 L

Final temperature = ?

Solution:

According to Charles's law,

V∝ T

V = KT

V₁/T₁ = V₂/T₂

T₂ = V₂T₁/V₁

T₂ = 0.285 L × 283 K / 0.250 L

T₂ =  80.655 L.K /0.250 L

T₂ = 322.62 k
