Ideal gas law

PV = nRT

P/nR = T/V in your question's situation P is consatnt n is constant and R is the ideal gas constant....so the entire left side of this equation is a constant....let's call it ' k '

so

k = T1/V1 = T2/V2 when dealing with gas laws T MUST BE IN Kelvin degrees !!!

20 C = 273.15 +20 K = 293.15K

soooo....

293.15 k / 2L = x/ 1L x is the temp (in Kelvin we are looking for)

x = 293.15/2 = 146.58 k 146.58-273.15 = - 126.58 C

Note that temperatures in Kelvin do __not__ use degrees. The unit measure is simply Kelvin(s).

Correct-a-mundo ! Just hoping to avoid confusion for those learnig the system....
