Avogadro’s law and charles’s law describe a proportionality of the volume of a gas when the pressure is constant. which describes the proportionality that allows these laws to be combined when describing a gas?
volume is directly proportional to temperature (avogadro’s law) and to moles (charles’s law).
volume is inversely proportional to temperature (avogadro’s law) and to moles (charles’s law).
volume is directly proportional to moles (avogadro’s law) and to temperature (charles’s law).
volume is inversely proportional to moles (avogadro’s law) and to temperature (charles’s law).

Answer : The correct option is, Volume is directly proportional to moles (Avogadro’s law) and to temperature (Charles’s law).

Explanation :

As we know that, there are four law of gas which are :

1) Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

    (At constant temperature and number of moles)

2) Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

   (At constant pressure and number of moles)

3) Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

    (At constant volume and number of moles)

4) Avogadro's Law : It is defined as the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

  (At constant temperature and pressure)

Hence, from the above information we conclude that the correct option is, Volume is directly proportional to moles (Avogadro’s law) and to temperature (Charles’s law).

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
