SCIENTIFIC LAWS - PART 1
ARCHIMEDE'S PRINCIPLE
It states that a body when wholly or partially immersed in a liquid, experiences an upward thrust which is equal to the weight of the liquid displaced by it. Thus, the body appears to lose a part of its weight. This loss in weight is equal to the weight of the liquid displaced by the body.
AUFBAU PRINCIPLE
It states that in an unexcited atom, electrons reside in the lowest energy orbitals available to them.
AVOGADRO'S LAW
It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
BROWNIAN MOTION
It is a zigzag, irregular motion exhibited by small solid particles when suspended in a liquid or gas due to irregular bombardment by the liquid or gas molecules.
BERNOULLI'S PRINCIPLE
It states that as the speed of a moving fluid, liquid or gas, increases, the pressure within the fluid decreases. The aerodynamic lift on the wing of an aeroplane is also explained in part by this principle.
BOYLES'S LAW
It states that temperature remaining constant, volume of a given mass of a gas varies inversely with the pressure of the gas. Thus,
PV = K (constant), where, P = Pressure and V = Volume.
CHARLES'S LAW
It states that pressure remaining constant, the volume of a given mass of gas increases or decreases by 1/273 part of its volume at 0 degree celsius for each degree celsius rise or fall of its temperature.
COULOMB'S LAW
It states that force of attraction or repulsion between two charges is proportional to the amount of charge on both charges and inversely proportional to the square of the distance between them.
HEISENBERG PRINCIPLE (UNCERTAINTY PRINCIPLE)
It is impossible to determine with accuracy both the position and the momentum of a particle such as electron simultaneously.
GAY-LUSSAC’S LAW OF COMBINING VOLUMES
Gases react together in volumes which bear simple whole number ratios to one another and also to the volumes of the products, if gaseous — all the volumes being measured under similar conditions of temperature and pressure.
GRAHAM’S LAW OF DIFFUSION
It states that the rates of diffusion of gases are inversely proportional to the square roots of their densities under similar conditions of temperature and pressure.
