Consider a cold aluminum canned drink that is initially at a uniform temperature of 4°c. the can is 12.5 cm high and has a diameter of 6 cm. if the combined convection/radiation heat transfer coefficient between the can and the surrounding air at 25°c is 10w/m^2°c, determine how long it will take for the average temperature of the drink to rise to 15°c. in an effort to slow down the warming of the cold drink, a person puts the can in a perfectly fitting 1-cm-thick cylindrical rubber insulation (k=0.13w/m°c). now how long will it take for the average temperature of the drink to rise to 15°c
