I learnt all of these at school, but I've always struggled to remember which is which.
| Equal volumes of different gases, at the same temperature and pressure, contain the same number of molecules |
 |
Avogadro's Law |
| For a given mass of gas at constant temperature, the pressure is inversely proportional to the volume |
|
Boyle's Law |
| For a given mass of gas at constant pressure, the temperature is directly proportional to the volume |
|
Charles's Law |
| For a given mass of gas at constant volume, the pressure is directly proportional to the temperature |
|
Gay Lussac's Law |
First stated in 1834 by the French engineer and physicist Benoît Paul Émile Clapeyron (one of the
founders of thermodynamics) as a combination of the above four laws |
|
Ideal Gas Law |
| Also published the Law of Combining Volumes: that when gases react together, they do so in volumes that bear a simple whole number ratio to each other and to the volumes of any gaseous products formed (provided that the temperature and pressure remain constant) |
|
Joseph Louis Gay–Lussac |
| First |
|
A body remains in a state of rest or uniform motion, unless acted upon by a force |
| Second |
|
Rate of acceleration is directly proportional to the force |
| Third |
|
For every action there is an equal and opposite reaction |
| First |
|
Energy can neither be created nor destroyed; the amount of energy lost in a process
cannot be greater than the amount of energy gained |
| Second |
|
Energy systems have a tendency to increase their entropy rather than to reduce it
|
| Third |
|
There is a temperature (absolute zero) at which the entropy of any system is constant;
as the temperature of the system approaches that temperature, its entropy approaches that constant |
| Zeroth |
|
If A, B and C are distinct thermodynamic bodies, and both A and C are in thermodynamic
equilibrium with B, then A is also in thermodynamic equilibrium with C
|
| Q: Which law (or whose law) states that ... ? | A: | |
| The energy equivalence (E) of a given mass (m) is that mass times the square of the speed of light in a vacuum (c). In other words: E = mc2 (proposed by Albert Einstein in 1905) |
|
"The energy equation" |
| When a body is wholly or partially immersed in fluid, it is acted upon by a buoyant force (or upthrust) equal to the weight of the displaced fluid |
|
Archimedes' Principle |
| A robot may not injure a human being or, through inaction, allow a human being to come to harm |
|
Isaac Asimov's First Law of Robotics |
| For a fluid in motion, an increase in speed occurs simultaneously with a decrease in pressure or potential energy |
|
Bernoulli's Principle |
| If your back is to the wind, low pressure is on your right (in the Northern Hemisphere) |
|
Buys Ballot's Law |
| The pressure exerted by a mixture of gases in a fixed volume is equal to the sum of the pressures exerted by each gas if it occupied that volume alone |
|
Dalton's Law of Partial Pressures |
| There are no positive integers x, y, and z such that xn +
yn = zn in which n is a natural number greater than 2
|
|
Fermat's Last Theorem |
| The rate of effusion (flow through a hole) in a gas is inversely proportional to the square root of the mass of its particles |
|
Graham's Law |
| For an elastic material, strain is proportional to applied stress (or, extension is proportional to the force applied) |
|
Hooke's Law |
| The power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the current |
|
Joule's First Law |
| The planets orbit the sun in elliptical orbits with the sun at one focus |
|
Kepler's First Law |
| The line connecting a planet to the sun sweeps out equal areas in equal amounts of time |
|
Kepler's Second Law |
| The time required for a planet to orbit the sun, called its period, is proportional to the long axis of the ellipse raised to the power of 3/2. The constant of proportionality is the same for all the planets |
|
Kepler's Third Law |
| A system in chemical equilibrium, if subjected to a disturbance, tends to change in a way that opposes the disturbance |
|
Le Chatelier's Principle |
| The direction of current induced in a circuit by a change in magnetic field is such that the magnetic field produced by this current will oppose the original field |
|
Lenz's Law |
| Cod law with no scientific basis, stating that in any given system, if anything can possibly go wrong, it will.
For example, if you drop a piece of toast, it will always land buttered side down (except when you drop it deliberately to prove the law).
Can be seen as an ironic, unscientific version of the second law of thermodynamics
|
|
Murphy's Law |
| Of two equivalent theories or explanations, all other things being equal, the simpler one is to be preferred |
|
Occam's Razor |
| The current between two points (through a conductor) is directly proportional to the potential difference across them (I = V/R) |
|
Ohm's Law |
| Work expands so as to fill the time available for its completion |
|
Parkinson's Law |
| In a right angled triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides |
|
Pythagoras's theorem |
