Sadi Carnot discovered that the transformation of heat into mechanical energy could only occur when thermal energy flows from a hot object to a cool object. he also discovered that in this process some heat was always lost.

Why gravity is the powerful force in nature?
Because (1) It extends to arbitrarily long distances, unlike some other forces. (2) Unlike electricity and magnetism, which also extend to arbitrary distances, it is always attractive. The result is that the (tiny) contributions of lots of individual particles contribute to one great force.

Is it possible to attain an efficiency of 100 percent in heat engines.explain?
A heat engine operating between 2 temperatures, Thot, the heat source, and Tcold, the heat sink, can be 100% efficient only when Tcold is absolute zero. Carnot worked out the equation to determine the best possible efficiency of a heat engine designed to produce mechanical energy ("Work") from heat energy: Wout = (Heat Energy in at Thot) x (Thot - Tcold)/(Thot) Note that (Thot - Tcold)/(Thot) is 1 only if Tcold is zero. In every other case, the ratio is less than 1. The amount of heat energy discharged to the heat sink at Tcold is: (Heat Energy in at Thot) - Wout. (You can work this out from the equation. It reflects the law of conservation of energy. ) This just means that all the heat energy absorbed by the heat engine is converted into either mechanical energy or heat energy at a lower temperature. No energy is lost and no extra energy is created. "Efficiency" according to Carnot's equation tells us the best possible ratio between these two energy outputs that nature allows a heat engine to achieve. You can think of a heat engine as a device that splits an amount of heat energy at some high temperature into mechanical energy and heat energy at some lower temperature.

When was Nature Physics created?
Nature Physics was created in 2005.
Why refrigeration cycle is called reverse carnot cycle?
The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.

What is the second law of thermodymanics?
There are several equivalent formulations for this law, for example:No heat machine can have an efficiency above that of the theoretical Carnot engine.Entropy increases.Useful energy is continually converted into unusable energy.There are irreversible processes in nature.
