    Q.4. a- A 1-kg iron block is to be accelerated through a process that supplies it with 1 KJ of energy. Assuming all this energy appears as kinetic, what is the final velocity of the block?

    b- If the heat capacity of iron is 25.10 J/(mol K) and the molecular weight of iron is 55.85, how large a temperature rise would result from 1 KJ of energy supplied as heat?
