an ideal gas in a closed inflexible container has a pressure of 6 atm and a temperature of 27 degree celsius . What will be the new pressure of the gas of temperature is decreased to -73 degree celsius?

a) 2 atm
b) 3 atm
c) 4atm
d) 8atm
e) 9atm

plz teach me the method also

• chemistry -

(P1/T1) = (P2/T2)
Substitute into the equation and solve for the one unknown. Remember T must be in kelvin.

m not getting the right answer am getting a different ans

• chemistry -

Post your work and I'll find the error,

• chemistry -

6/27 = p1/-73 ths are the values which m getting frm question bt stil the last ans is like 438 which is obviously wrong

• chemistry -

Re-read my first response. Didn't I say to remember T must be in kelvin? That was not a typing exercise for me. Students often forget to change celsius to kelvin; I almost always write that as a reminder. You used celsius, not kelvin. You can't get the right answer without using kelvin for T.
Do you know how to convert T from C to K?
K = C + 273.
