Assume that a can of soda was held at a steady temperature (say 4°C) in a fridge for a long time. Then it is placed on a desk in a classroom. Describe the temperature evolution in the can. In your model, what is the temperature in the center of the can after 10 seconds, 1 minute. 5 minutes, 10 minutes, and 30 minutes, after it was taken out of the fridge? (Find the numerical values of the temperature, not just a formula!) Discuss, whether the answer obtained (and model used) is reasonable or not. Furthermore, you may want to discuss the influence of parameters of the problem (size of the can, classroom temperature, different outer shell materials, pressure in the can, drinking from the can, etc.) on the process.

Assuming an even heating effect around the can but NOT from underneath you will see the gradual evolution of an elongated toroid with fluid flow up the inside wall of the can and tending again down through the middle.
If the heating source is from the base then you will see the formation of mini thermoclimes that will be released once the viscosity limit of the fluid has been reached.
maybe....I dont buy soda in glass cans and I usually drink it before it gets warm
