WebΔT is temperature change. Strictly this is in Kelvin. But ΔT = Tfinal - Tinitial. And it won't make any difference whether you use Kelvin or Celsius to work it out. ΔT = 283.15K - 0K = 283.15K. ΔT = 10oC - -273 oC = 283.15 oC and a difference of is also a difference 283.15 K. At GCSE Q=mcΔT would have been enough, but an A level paper is ...
