Question #de777

Answer 1

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"`
