# 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

**Organize your data:**

**Unknown**

**Solution**

Rearrange the equation given above to isolate

To convert from Kelvins to degrees Celsius, subtract
