A gas has a pressure of 2.0 atm. If the temperature decreases from 250K to 125K and the volume remains constant, what will be the resulting pressure?

203 kPa ÷ 273 K = P2 ÷ 323 K

V1/T1 = V2/T2. then make it Kelvin and plug it

Hey there,

We need to remember to use the P1/T1 = P2/T2 method.

203 kPa ÷ 273 K = P2 ÷ 323 K

V1/T1 = V2/T2. Convert your temps to Kelvin, plug in and solve for V2.

Your correct answer is
\boxed{P2 = 240 kPa}
