Question

Heat is added to a silver bar of mass 0.034 kg and length 0.28 m. The bar expands by an amount of 3.8×10-4 m. How much heat was added?
I need the answer and the equation please thanks!

Answer 1

no work to show?

Answer 2

deltaL= L *coefflinearexpansion*deltaTemp
but deltaTem= heatadded/(mass*coefheating)
solve for heat added. The coefficnets of heating, and coefficinets of silver can be looked up.
