Thermodynamics in a coke can

Heat transfer is a principal concept required to understand further level of thermal dynamics and energy equations. The problem stated takes in to account a simple convection mode through the use of a can of coke filled with water, left to rise to room temperature. The water in the can is first lowered to 40 degrees Fahrenheit, and then taken out as time begins to be taken periodically. After the accordant time has passed the water should be room temperature and the experiment is over. The time taken for the heat to transfer from the air to the water took about an hour. This can be plotted on a graph to show how heat transfers slows down after it begins to reach the 70 degree Fahrenheit mark because the difference in temperature with respect to time starts to decrease. This shows how heat transfer works between a solid or still fluid and a moving fluid in its surrounding with a significantly higher temperature. Understanding these results is the first step in beginning to implement heat transfer in to more complicated situations.
