The gas should be kept at -248 degrees C.

#### Explanation:

Use Charles Law. Temperature and Volume are directly related using degrees Kelvin. ( if the pressure and number of molecules are kept constant.

# T_2 = unknown

Substituting these numbers into the equation gives

# T_2 = 24.6 degrees K

Subtract 273 to find degrees C.
