A gas at temp. of 27C is heated at constant pressure to triple its volume.the final temp of the gas will be?

From the ideal gas law PV=nRT: if P (pressure) is constant, and n (number of moles of gas) is constant, and R is a constant, then if V goes up by a factor of 3 what must happen to T? The only trick here isto remember to do the calculation in Kelvins, not degrees celsius.
