Answer to Question #131428 in General Chemistry for Juju

Question

If a 10-0 L sample of gas at STP is heated until its volume is 2`1 L and it’s temperature is 451 Celsius degrees, what is the new pressure in kPa

Answer 1

T₂ = 451 + 273.15 = 724.15 K

P1V1/T1 = P2V2/T2

$101.325 kPa * 10 L / 273.15 K = P2 * 2.1 L / 724.15 K$

P2 = 1279.2 kPa
