An aluminum frying pan of mass 1.5 kg is at 180oC, when it is plunged into a sink containing a mix of 4.5 L water and 0.5 kg of ice at its melting point (i. e., water and ice are in equilibrium at 0oC). Assuming that none of the water boils and that no heat is lost to the surroundings, find the equilibrium temperature of the water and the pan.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
