Charles' law states that if pressure remains constant, the temperature and volume of a gas are directly proportional, so that as temperature increases, so does the volume. The equation for this law is:

#"V"_1/"T"_1# = #"V"_2/"T"_2#

Given:
#"T"_1# = #"129K"#
#"V"_2# = #"185L"#
#"T"_2# = #"325K"#

Solution:

Cross multiply.

#"V"_1"T"_2# = #"V"_2"T"_1#

Solve for #"V"_1#.

#"V"_1# = #"V"_2"T"_1"/T"_2"#

#"V"_1"# = (#"185L"#)(#"129K"#)#/##"325K"# = #"73.4L"#
