Answer to Question #1933 in Molecular Physics | Thermodynamics for shubhi

Question

Hello there,

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.

Thank you,

Shubhi

Answer 1

In SI
m & = [kg]
C = [J/kg K]
ΔT = [K]
Q=mcΔT = [kg* J/(kg K) * K] = [J]
