If the initial temperature of an ideal gas at 2.250 atm is 62.00 #"^o#C, what final temperature would cause the pressure to be reduced to 1.500 atm?

Answer:

With a constant amount of gas, #P_1/T_1=P_2/T_2#, according to Charles' Law.

Explanation:

So, we convert the temperatures to the absolute scale, and solve the quotient:

#T_2=(T_1xxP_2)/P_1=(335.15*Kxx1.500*atm)/(2.250*atm)=223*K#

You should convert this temperature back to the #"Celsius scale"#. It is intuitively sound that a decrease in temperature should result in a decrease in temperature. Why?
