A sample of sulfur hexafluoride gas occupies 8.62 L at 221 degrees Celsius. Assuming that the pressure remains constant, what temperature (in Celsius) is needed to reduce the volume to 2.61 L?
1 Answer
The temperature needed to reduce the volume from
Explanation:
Your variables,
Charles' law states that the volume of a given amount of gas held at constant pressure is directly proportional to its Kelvin temperature. This means that as the temperature increases, the volume also increases, and vice-versa. The equation used to solve gas problems involving Charles' law is:
where the temperatures must be in Kelvins. Add

Solution
Rearrange the equation given above to isolate
To convert from Kelvins to degrees Celsius, subtract
