Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature And pressure are constant.

Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase
: No 2c(iii)
Pick any three
-Oxygen is a colorless, odorless, tasteless gas.
-it changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F).
-temperature of -182.96°C (-297.33°F). ... The three allotropes ofoxygen are normal oxygen, or diatomicoxygen, or dioxygen; nascent, atomic, or monatomic oxygen; and ozone, or triatomic oxygen.
-is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element.
-Chemical Formula : O. Oxygen gas (O2). Ozone (O3)
-Combustion : Supports combustion but does not burn
-Oxidation : The common reaction in which it unites with another substance is called oxidation. Oxides of some metals form peroxides by the addition of oxygen
