2) Water at room temperature of 20.0'C
is
poured into an aluminum cylinder which has graduation
markings etched on the inside. The reading in the graduations is 300.0cc.The cylinder with the
water in it is then immersed in a constant temperature bath at a temperature of 100'C. What is the
reading for the level ofwater on the graduations of the cylinder after the water and the cylinder
reach thermal equilibrium with the bath? The volume coefficient of expansion of water is 2.07 •

4) It is a wellknown fact that water has ahigher specific heat capacity than iron. Now, consider
equal masses of water and iron that are initially in thermal equilibrium. The same amount of heat,
