Math Solution of Second Law Of Thermodynamics

by

The second law of thermodynamics states that the entropy of an isolated system never decreases, because isolated systems spontaneously evolve towards thermodynamic equilibrium—the state of maximum entropy. Equivalently, perpetual motion machines of the second kind are impossible. The second law is an empirically validated postulate of thermodynamics, but it can be understood and explained using … Read more

Waves and Sound

by

Sound wave is one of the most recognizable characters from the original Transformers line. He had an alternate mode – a microcassette recorder – and possessed a distinctive monotone, computerized voice. Soundwave is able to identify and jam transmissions across the entire energy spectrum, a talent that makes him suited to his position as Decepticon … Read more

Speed Of Sound

by

Speed Of Sound The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one … Read more

Static Electricity

by

Static Electricity Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is named in contrast … Read more
