You have a cylindrical beverage container that has been sitting in your hot car all day, and is now at a temp of 50 deg C. It will now be placed into your refrigerator to cool down by natural convection. The air temp inside your refrigerator is 4 deg C (assume P=1atm). Based on this initial condition, calculate whether you should place the beverage container standing upright, or laying on its side in order to cool it faster. The beverage container has a diameter of 65mm, and a height of 100mm; ignore any end effects and radiation.
