Question

a gas is collected at a pressure of 95 cm of hg and at a temperature of 50 c to what temperature should it be cooled so that it occupies a volume of 80 percent of its original volume when pressure of the gas is 90 cm of hg

Answer 1

Answer:

The principle of least time: Light always takes the quickest path between any two points (which may not be the shortest path).

The principle of least time: Light always takes the quickest path between any two points (which may not be the shortest path).Rectilinear propagation of light and the law of reflection [∠i=∠r] can be validated by Fermat’s principle of least time.

Answer 2

Answer:

The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro's law).
