Answer 2

A gaseous material has a strong smell, evaporates quickly, particularly boils at - $33.34^\circ C$ and melts at$-77.73^\circ C.$ This matter can be classified as"(D) Substance".

Explanation:

• A substance is a type of matter having a consistent chemical makeup and distinct features.
• Furthermore, physical separation methods cannot separate chemical compounds into their basic elements.
• Breaking chemical bonds is required to separate a material into its basic elements.
• Chemical substances come in a variety of forms, including the following:Simple substances ,Chemical compounds ,Alloys.
• The adjective "pure" is added to distinguish chemical compounds from mixtures. Pure water, pure gold, pure table salt, and pure refined sugar are just a few examples.
• Not all substances are compounds, but all compounds are substances.
• Natural compounds that appear to be simple or pure can really be chemical combinations.
• A pure gas is a material that exists as a gas under normal conditions ($1$atm,$273 K$) and has a volume of $22.4 L$ per mole (ignoring any substance-specific intermolecular forces or particle volume that could affect this value).
• If a substance's boiling point is less than $273 K$, you can assume it's in gas form.
• Compounds, too, are pure substances. The chemical formulae of sodium chloride ($NaCl$), water ($H_2O$), methane ($CH_4$), and ethanol ($C_2H_5OH$) indicate a link between the number and kind of atoms they contain.
