120MJ of heat are used to heat up a 1100kg component from 22oCelsius to 180oCelsius, in 1 hour, prior to heat treatment. If the specific heat capacity of the components material is 500J/kg, calculate the efficiency of the heating process.(adsbygoogle = window.adsbygoogle || []).push({});

Please could somone give me the equation that i need to work out the efficenency i will then subit my attempt thx
