3-In this experiment, we will measure the heat loss of an object and heat gain of another during a heat exchange process. The heat loss and heat gain are supposed to be equal to each other. However, your measurement find that the heat loss is 3.98 J while the heat gain 3.23 J.What is the percent difference of the two values?
