2010. Suppose that a 10 kg mass of iron at 20 C is dropped from a heigh of 100 meters. What is
the kinetics energy of the mass just before it hits the ground, assuming no air resistance? What is
its speed? What would be the final temperature of the mass if all the kinetic energy at impact is
transformed into internal energy? The molar heat capacity of iron is Cpp = 25.1J mol-¹ K-1
and the gravitational acceleration constant is 9.8 m s¯² |
