Question

The pressure of a gas is reduced from 1200. 0 mm hg to 850. 0 mm hg as the volume of its container is increased by moving a piston from 85. 0 ml to 350. 0 ml. What would the final temperature be if the original temperature was 90. 0 °c?.

Answer 1

Answer: T2=233K

Step-by-step explanation:

The pressure and volume change. The combined gas law is always needed for that concept.

P1*V1/T1=P2*V2/T2

Temperature MUST ALWAYS be in Kelvin

T1=90+273=363K

1200*85/363=850*350/T2

T2=233K

Hope this helps! :)
