Efficiency of the heating process

AI Thread Summary
To calculate the efficiency of the heating process, the equation to use is efficiency equals the heat required divided by the heat supplied. The heat required can be calculated using the formula Q = mass x specific heat capacity x change in temperature. In this case, 120MJ of heat is supplied to heat a 1100kg component from 22°C to 180°C, with a specific heat capacity of 500J/kg. After performing the calculations, the efficiency can be determined by comparing the heat required to the heat supplied. This approach will yield the efficiency of the heating process effectively.

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.

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

Efficiency, in this sense, would be (heat added to the component)/(heat used to heat up the component).
 
Check units on specific heat. Eff=heat required/heat supplied
