This defines Entropy, a function of state. dS = đqrev⇒ S = S − S = 2 đqrev T 2 1 ∫1 T Note: Entropy is a state function, but to calculate S requires a reversible path. An irreversible Carnot (or any other) cycle is less efficient than a reversible one.

a Volt (V) is a Joule (J) of work per Coulomb (C) of charge [1V = 1J/1C] ... Ohm’s Law. defines relationship between voltage, current and resistance. current in a resistor varies in direct proportion to the voltage applied to it and is inversely proportional to the resistor’s value.

Dalton’s theories also lead to the discovery of the third law of chemical reactions. This is the law of multiple proportions. It states that “whenever two elements form more then one compound the different masses of one that combine with the same mass of the other …

Engineers apply this law to design springs for different kinds of instruments via simple calculations in accordance with Hooke’s law. A good (useful) law accounts for all of the facts among variables. Many laws have limits because they apply to only certain situations. A limited law proves less useful in predicting new facts.

This unit conversion factor was called the “mechanical equivalent of heat.” In today's parlance, we should say that Joule measured the heat capacity of water in units of m2•s-2•K-1. The apparatus that Joule used in shown on the next page. (He actually used several experimental designs, but this apparatus is the most direct one to ...

According to a series of experiments conducted by Joule in 1843, u depends only on T , a relationship known as Joule's Law. It can also be shown (e.g., this was used in the derivation of the equation of state using statistical mechanics, Ch. 2 notes) that for an ideal monatomic gas, the kinetic energy of translations is given by

Newton's first law defines what a force is, namely any physical effect that is capable of changing the motion of an object. If an object is at rest or in uniform motion, either no force acts on it or forces do act on it and the resultant force is zero. ... The SI unit of energy and of work is the joule (J). Work and energy are . scalar quantities.

The English system defines force to be a basic physical quantity. Hence the unit for force is a base unit and the unit for mass becomes a derived unit. The base unit of force defined in the English system is called a pound (lbf). From Newton’s second Law: F = ma or force = (mass) x [(length) /

With increasing concentration and intensity, greater current density occurs in the depths of the tissue. Joule’s law states that as the resistance of a tissue increases, there is more electrical energy converted into heat. The relationship is expressed as follows: P = I2 X …
