A cylinder with a movable piston contains gas at a temperature of 27 degrees celsius, a volume of 1.50 meters cubed, and an absolute pressure of 0.200 X 10 to the fifth Pa. What will be its final temperature if the gas is compressed to 0.700 meters cubed and the absolute pressure increases to 0.800 X 10 to the fifth Pa?
This seems like chemistry, not physics.
Use the combined gas law PV/T=PV/T and solve for T.
[(0.2 x10^5 Pa)(0.8 x10^5)]/27=T
T₁ =27+273=300 K
T₂ = T₁•p₂V₂/p₁V₁= …. K (!)
opps, sorry about the rearranging of the formula and she is right you have to convert to kelvins before doing the math.
287 degrees Celsius
