Item NG081003: The total energy inside a closed cooler filled with ice and a can of soda stays the same even though the can of soda gets colder, because the amount of energy that the can of soda lost is equal to the amount of energy that the ice gained.
|
In the morning, a student puts a warm can of soda in a cooler filled with ice.
He closes the cooler. At lunch, the can of soda is colder. What happened to the total amount of energy in the cooler containing the can of soda and the ice? (Assume that no energy is transferred into or out of the cooler when it is closed.)
