In one box, there are 75 iron nails weighing 0.250 lb. The density of iron is 7.86 g/cm3. The specific heat of iron is 0.452 J/g °C.

a. What is the volume, in cm3, of the iron nails in the box?

b. If 30 nails are added to a graduated cylinder containing 17.6 mL of water, what is the new level of water in the cylinder?

c. How much heat, in joules, must be added to the nails in the box to raise their temperature from 16 °C to 125 °C?

d. If all the iron nails at 55.0 °C are added to 325 g of water at 4.0 °C, what will be the final temperature (°C) of the nails and water?

Nails made of iron have a density of 7.86 g/cm3
