a vector quantity whose magnitude is speed and whose direction is the direction of motion; v = displacement (x) / time (t) SI units = meters/second (m/s) Average Velocity. average velocity (v, with a line over it) = Δx / Δt. Speed (s) the rate of actual distance traveled in a given unit of time:

1.1 Chemistry in Context. Chemistry deals with the composition, structure, and properties of matter, and the ways by which various forms of matter may be interconverted. Thus, it occupies a central place in the study and practice of science and technology.
P 1 V 1 = P 2 V 2. Where, P 1 is the initial pressure exerted by the gas; V 1 is the initial volume occupied by the gas; P 2 is the final pressure exerted by the gas; V 2 is the final volume occupied by the gas; This expression can be obtained from the pressure-volume relationship suggested by Boyle’s law. For a fixed amount of gas kept at a ...
- Boyle’s law is a gas law that states that a gas’s pressure and volume are inversely proportional. When the temperature is kept constant, as volume...
- Boyle’s law is significant because it explains how gases behave. It proves beyond a shadow of a doubt that gas pressure and volume are inversely pr...
- The empirical relation asserts that the pressure (p) of a given quantity of gas changes inversely with its volume (v) at constant temperature; i.e....
- A balloon is a good example of Boyle’s law in action. The balloon is inflated by blowing air into it; the pressure of the air pulls on the rubber,...
- Boyle’s law is a connection between pressure and volume. It asserts that under constant temperature, the pressure of a specific quantity of gas is...
- Boyle’s law is a gas law given by the Anglo-Irish chemist Robert Boyle in 1662. He stated that the pressure exerted by a gas is inversely proportio...
- The pressure and volume are inversely proportional to each other under Boyle’s law. P ∝ (1/V)
- Volume decreases with increasing pressure because the gas particles come close to each other with increasing pressure. Similarly, volume increases...
- For a fixed mass of gas at a constant temperature, pressure is inversely proportional to volume. If the volume is doubled, the pressure will be hal...
Covalent bonding is the sharing of electrons between atoms. This type of bonding occurs between two atoms of the same element or of elements close to each other in the periodic table. This bonding occurs primarily between nonmetals; however, it can also be observed between nonmetals and metals. If atoms have similar electronegativities (the ...
