The volume of a sample of ideal gas at 25*C is 372ml. What will be the volume of the gas if it is heated at constant pressure to 50*C? What will be the volume of the gas if it is cooled to -272*C?

Answer 1

(V1/T1) = (V2/T2)

Don't forget T must be in kelvin.

Answer 2

What will be the volume of the gas if it is heated at constant pressure to 50 degrees Celsius?

First, convert mL to L and Celsius to Kelvin:

372 mL = .372 L
25 degrees C = 298 degrees K
50 degrees C = 323 degrees K
-272 degrees C = 1 degree K

Then, set up your equation:

.372L/298K=V2/323K
and
.372L/298K=V2/1K

Now, solve:

.403 L at 50 degrees Celsius

.001 L at -272 degrees Celsius

Answer 3

343 ml
