One liter of gas is measured out at 37 degree Celsius at a constant pressure . What volume will it occupy at -25 degree Celsius

Respuesta :

MathPhys

Answer:

0.8 L

Explanation:

Ideal gas law: PV = nRT

At constant mass and pressure, nR/P = nR/P.

Therefore, V/T = V/T.  (Remember to use absolute temperature.)

V/T = V/T

1 L / (37 + 273 K) = V / (-25 + 273 K)

V = 0.8 L
