A gas occupies a volume of 0.560 L in a flexible container at a temperature of 393 K. To what temperature must the gas be lowered if we desire it to occupy a space of 0.400 L?

The answer to your question is  T2 = 280.7 °K

Explanation:

Data

Volume 1 = V1 = 0.56 l

Temperature 1 = T1 = 393°K

Volume 2 = V2 = 0.40 l

Temperature 2 = T2 = ?

Process

To solve this problem use Charles law.

             V1/T1 = V2/T2

-Solve for T2

             T2 = V2T1 / V1

-Substitution

              T2 = (0.40 x 393) / 0.56

-Simplification

               T2 = 157.2/0.56

-Result

              T2 = 280.7 °K

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
