Answer to Question #42794 in Molecular Physics | Thermodynamics for delnaaz

Question

Kiwis love a summer barbecue, but there is nothing worse than having a hot drink
on a hot day. Luckily, you happen to know a bit about thermodynamics and heat
transfer, so have decided to design yourself a chilly-bin. You have six 355mL cans of
drink at 8°C that you don’t want to get above 10°C for the three hours before the
barbecue (the ambient temperature is 28°C), but you don’t have any ice. The air
over the outside of your chilly bin can be assumed to have a heat transfer coefficient
of 5 W/m2
K. Show a sketch, your calculations (and any assumptions you have made)
and provide a 250 word discussion justifying your design.
