In the standard AQA chemistry AS book on the Enthalpy change section it tells us we have to convert Celsius to kelvin in the equation:
q = mc (delta)T
However in numerous past papers such as June 2010 Q.8d the temperature is in Celsius, 8C why don't we convert it?

You only have to convert temperature into kelvin for the perfect gas equation in AS unit 1 (pV=nRT) whereas in unit 2 the calculation is for q=mc(delta)T and delta t is temperature change so it doesn't make a difference whether its in kelvin or celcius.
