If a sample of gas occupies 6.8 L at 325 degrees C, what will its volume be at 25 degrees C if the pressure does not change?
Answered by oobleck
Since PV=kT, you have, if P is constant,
V/T = k/P, a constant
You want V such that
V/(25+271) = 6.8/(325+271)

oops. typo
That 271 is a 273 in both instances.
