At -40°C, a sample of gas has a volume of 233 mL. On heating, the volume expands to 313 mL. Assuming constant pressure, what is the new Celsius temperature?
The new temperature in degrees Celsius is 40 degrees C.
This isthe an example of Charles' law which states the volume of a gas that is held at a constant pressure varies directly with the Kelvin temperature. The formula used to solve this problem is
Rearrange the equation to isolate
Convert temperature in Kelvins to degrees Celsius.
