The volume of a gas is 1.00 L at 12 C. If the pressure remains constant, to what temperature (in C) must the gas be heated to triple the volume?

Remember that Charles law states that volume and temperature are inversely proportional.  Mathematically this is stated as

V1 / T1 = V2 / T2

The most important thing to remember is that temperature must always be used in Kelvin.  (volumes and pressures can be used in any unit)

The given information includes:

V1 = 1 L

V2 = 3 L

T1 = 12 degC = 285 K

Using the equation above, you can solve for T2

T2 = V2 / V1 * T1

T2 = 3L / 1L * 285 K

T2 = 855 K = 582 degC
