Carnot`s Perfect Heat Engine: The Second Law of
... This novelty toy, known as the drinking bird, is an example of Carnot's engine. It contains methylene chloride (mixed with a dye) in the abdomen, which boils at a very low temperatureabout 100ºF. To operate, one gets the bird's head wet. As the water evaporates, uid moves up into the head, causing ...

Basics of Thermodynamics
... If a block of material (at T) is in contact with surrounding at (TT), then ‘heat will flow’ into the surrounding. Now if the temperature of the surrounding is increased to (T+T), then the direction of heat flow will be reversed. If a block of material (at 40C) is contact with surrounding at ...

... volume and Avogadro in 1811 was the 1st to propose that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. If we know the weight of a given volume of gas, we can determine its molecular weight. For example one liter of hydrogen weighs 0.09 grams, and one ...
