1. How is the product solution used to determine the variation of temperature with time and position in three-dimensional systems?

2. A short cylinder initially at a uniform temperature T_i
is subjected to convection from all of its surfaces to a medium at temperature
. Explain how you can determine the temperature of the midpoint of the cylinder at a specifi ed time.
