Question

If gas has a pressure of 954 atm and temp of 728 k and the temp changes to 951 k what is the new pressure ?

Answer 1

We have a change of pressure and temperature. To solve and find the new pressure we will assume that the volume and moles of the gas remain constant, therefore we can apply Gay-Lussac's law which tells us:

`(P_1)/(T_1)=(P_2)/(T_2)`

Where,

P1 is the initial pressure of the gas, 954atm

T1 is the temperature of the gas, 728K

T2 is the final temperature, 951K

P2 is the final pressure, =?

We clear P2 and replace the known data:

`\begin{gathered} P_2=(P_1)/(T_1)* T_2 \\ P_2=(954atm)/(728K)*951K=1246atm \end{gathered}`

Answer: The new pressure will be 1246atm
