Find an expression for the volume of the copper.
b) Find an expression for the increase in temperature of the copper AT if it
is supplied with an amount of heat Q at constant pressure. The density and specific
heat (heat capacity per unit mass) of copper at constant pressure are PCu and ccu
respectively. (You should treat these quantities as constants even though thermal
expansion will slightly reduce the density, for example).
c)

For heat transfer purposes, an egg can be considered to be a 5.5-cm-diameter sphere having the properties of water. An egg that is initially at 8°C is dropped into the boiling water at 100°C. The heat transfer coefficient at the surface of the egg is estimated to be 800 W/m2·K. If the egg is considered cooked when its center temperature reaches 60°C, determine how long the egg should be kept in the boiling water. Solve this problem using analytical one-term approximation method (not the Heisler charts).
