|Title:||PhysCasts: Shaking a Container of Water|
|Authors:||Hall, B. (Brenton)|
|Abstract:||This PhysCast is about the first law of thermodynamics. A closed by uninsulated container at room temperature containing 1 kg of water is shaken violently until the temperature rises by 5 degrees C. The mechanical work required in the process is 22 kj. a) How much heat is transferred during the shaking? b) How much mechanical energy would have been required had the container been perfectly insulating?|
