Examples of Boyle's law in the following topics:

  • Equations of State

    • The ideal gas law is the equation of state of a hypothetical ideal gas (in which there is no molecule to molecule interaction).
    • The ideal gas law is the equation of state of a hypothetical ideal gas (an illustration is offered in ).
    • It was first stated by Émile Clapeyron in 1834 as a combination of Boyle's law and Charles' law.
    • Boyle's law states that pressure P and volume V of a given mass of confined gas are inversely proportional:
    • Therefore, we derive a microscopic version of the ideal gas law

  • Isothermal Processes

    • (This is historically called Boyle's law. ) However, the cases where the product PV is an exponential term, does not comply.
    • In other words, the ideal gas law PV = nRT applies.
    • From the first law of thermodynamics, it follows that $Q =-W$ for this same isothermal process.

  • Adiabatic Processes

    • (This is historically called Boyle's law. ) However, the cases where the product PV is an exponential term, does not comply.
    • In other words, the ideal gas law PV = nRT applies.
    • From the first law of thermodynamics, it follows that $Q =-W$ for this same isothermal process.

  • Isotherms

    • For an ideal gas, the product PV (P: pressure, V: volume) is a constant if the gas is kept at isothermal conditions (Boyle's law).
    • According to the ideal gas law, the value of the constant is NkT, where N is the number of molecules of gas and k is Boltzmann's constant.

  • Gauss's Law

    • Gauss's law is a law relating the distribution of electric charge to the resulting electric field.
    • Gauss's law can be used to derive Coulomb's law, and vice versa.
    • In fact, Gauss's law does hold for moving charges, and in this respect Gauss's law is more general than Coulomb's law.
    • Gauss's law has a close mathematical similarity with a number of laws in other areas of physics, such as Gauss's law for magnetism and Gauss's law for gravity.
    • In fact, any "inverse-square law" can be formulated in a way similar to Gauss's law: For example, Gauss's law itself is essentially equivalent to the inverse-square Coulomb's law, and Gauss's law for gravity is essentially equivalent to the inverse-square Newton's law of gravity.

  • A Review of the Zeroth Law

    • Zeroth law justifies the use of thermodynamic temperature, defined as the shared temperature of three designated systems at equilibrium.
    • This law was postulated in the 1930s, after the first and second laws of thermodynamics had been developed and named.
    • It is called the "zeroth" law because it comes logically before the first and second laws (discussed in Atoms on the 1st and 2nd laws).
    • A brief introduction to the zeroth and 1st laws of thermodynamics as well as PV diagrams for students.
    • Discuss how the Zeroth Law of Thermodynamics justifies the use of thermodynamic temperature

  • Faraday's Law of Induction and Lenz' Law

    • This relationship is known as Faraday's law of induction.
    • The minus sign in Faraday's law of induction is very important.
    • Lenz' law is a manifestation of the conservation of energy.
    • Lenz' law is a consequence.
    • Express the Faraday’s law of induction in a form of equation

  • Hooke's Law

    • Many weighing machines, such as scales, use Hooke's Law to measure the mass of an object.
    • In simple terms, Hooke's law says that stress is directly proportional to strain.
    • Mathematically, Hooke's law is stated as:
    • In such a case, Hooke's law can still be applied.
    • The red line in this graph illustrates how force, F, varies with position according to Hooke's law.

  • Introduction and Importance

    • Kirchhoff's circuit laws are two equations first published by Gustav Kirchhoff in 1845.
    • Kirchhoff, rather, used Georg Ohm's work as a foundation for Kirchhoff's current law (KCL) and Kirchhoff's voltage law (KVL).
    • Kirchhoff's laws are extremely important to the analysis of closed circuits.
    • As a final note, Kirchhoff's laws depend on certain conditions.
    • The voltage law is a simplification of Faraday's law of induction, and is based on the assumption that there is no fluctuating magnetic field within the closed loop.

  • The Second Law

    • The second law of thermodynamics deals with the direction taken by spontaneous processes.
    • The law that forbids these processes is called the second law of thermodynamics .
    • Like all natural laws, the second law of thermodynamics gives insights into nature, and its several statements imply that it is broadly applicable, fundamentally affecting many apparently disparate processes.
    • We will express the law in other terms later on, most importantly in terms of entropy.
    • Contrast the concept of irreversibility between the First and Second Laws of Thermodynamics
