9.) Consider a cold aluminum canned drink that is initially at a uniform temperature of 3°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 10 W/m2-°C, determine (a)how long it will take for the average temperature of the drink to rise to 10°C. (b)ln 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= 0.13 W/m-°C). Now how long will it take for the average temperature of the drink to rise to 10°C? Assume the top of the can is not covered. (c) Assuming a thermal contact resistance of 0.00008 m2.°C/W between the can and the insulation. 3°C 12.5 cm T = 25°C air 6 cm

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
