Question #1933

Hello there,<br>

In our class we are doing heat capacity and we are using this formulae; Q=mcΔT. The problem is that I don't know if the answer will be in Joules, Kj or MJ. <br>

Thank you,<br>

Expert's answer

In SI

m & = [kg]

C = [J/kg K]

ΔT = [K]

Q=mcΔT = [kg* J/(kg K) * K] = [J]

m & = [kg]

C = [J/kg K]

ΔT = [K]

Q=mcΔT = [kg* J/(kg K) * K] = [J]
