Answer #1

Based on the heat capacity u calculated, now u know the amount of heat that can be transmitted to your hand on rubbing . Since the heat capacity is the amount of heat required to raise the temperature of 1gm of substance through 1°C. Based on assumptions , take intial body temperature as 37°C . And then equate the heat gained= heat lost . Knowing the specfic heat of human hand and inital temperature (t) the coin.

Mass of coin*specific heat*( t- x)= mass of hand * specific heat*( x-310K), where x is the final temperature when heat flow stops and both are in equilibrium
