\n1. Use the heat equation to calculate the number of joules of heat that will be gained or lost (specify which) when a copper penny (mass = 3.11 g) is removed from your pocket where it was at equilibrium with your body temperature of 37.1 \u00b0C and is placed on a nightstand and allowed to come to room temperature of 23.4 \u00b0C. Assume that the penney is pure copper. The specific heat of copper is 0386 J\/g\u00b0C. Specify the answer in J and in calories.
