Write an expression for the amount of heat required to raise the temp of the engine part by 150 degrees C?

An engine part is made of two 50 g pieces of different metals. ONe metal has specific heat .06 cal/g/degrees C and the other has specific heat C.

Write an expression for the amount of heat required to raise the temp of the engine part by 150 degrees C?
use Q = mc deltaT





convert mass to cal. T = 150, m = 50*2*factor to covert, c = take average of the two specific heat capacities
