I'm trying to do a calculation using: Heat transferred = mass x specific heat capacity x change in temperature q=mc∆T But the value I'm trying to calculate is the change in temperature so I've rearranged the equation to ∆T= q/mc I think the numbers and answer I have are correct, but the units are confusing me. My answer clearly needs to be in °C, the joules on the top and the bottom will cancel out but then on the bottom I'm left with kg multiplied by kg-1. 3.54 J 450 kg x 4.2 x 103 J kg-1 °C-1 As far as I know, these don't cancel eachother out so my answer has the wrong units. I don't know if I've done the entire thing wrong if I'm just confusing myself over something silly. I'd appreciate any help at all.
