The force that causes objects to float. The principle of Archimedes suggets that when a solid is placed in a fluid (a liquid or a gas), it is subject to an upward force equal in magnitude to the weight of the fluid it has displaced.
With atoms, what's really going on is that the space outside the nucleus is filled with the quantum fields that represent an electron.
his law states the pressure of a fixed quantity of gas held a constant temperature is inversely proportional to the volume of the gas
a hypothetical gas whose molecules occupy negligible space and have no interactions, and that consequently obeys the gas laws exactly.
the lowest possible temperature where nothing could be colder and no heat energy remains in a substance
Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion. These particles move in a straight line until they collide with another particle or the walls of the container.
boyle’s law suggests that the pressure of a fixed quantity held at a constant temperature is _______ proportional to the volume of the gas
the process of a substance spreading out to evenly fill its container or environment
the force that a gas exerts per unit surface area and in SI units is expressed as N/m^2. Other units of pressure measurements are in terms of atmospheres Pascals and lbs/in^2.

symbol Vm, is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ).
fixed quantity of gas can be accurately described in terms of the number of moles, volume, temperature, and pressure
law states the volume of fixed amount of gas, held at constant pressure is directly proportional to its absolute temperature.
the volume of a fixed amount of gas is inversely proportional to its pressure and directly proportional to its absolute temperature. The same quantity V being proportional to two other quantities.
