According to the ideal gas law, pressure and temperature of an ideal gas are directly proportional, and when one increases, the other also increases. Mathematically, P/T = constant.

If the absolute temperature is tripled, it means that the temperature will increase three times. Therefore, using the above equation, the pressure will also increase three times.

P1/T1 = P2/T2

P2 = (P1/T1) x T2

P2 = (P1/T1) x 3T1

P2 = 3P1

This means that the pressure will increase by a factor of 3. Therefore, the correct answer is C.
