Answer the following questions : (i)  A piece of iron is hammered.  Does the internal energy of the iron increase?  Does the heat enter the piece of the iron from outside? (ii)  A hot piece of lead is immersed in cold water.  Has the internal energy of the water increased?  Has any work been done by the lead? (iii)  Why are the brake-drums of a car heated when the car moves down a hill at constant speed? (iv)  Two balls of the same metal having masses 10g and 20g collide with a target with the same velocity.  If the total energy is used in heating the balls, which ball will attain higher temperature? (v)  An ideal gas is compressed at a constant temperature.  Will its internal energy increase or decrease? (vi)  How can the internal energy of an ideal gas be changed?
