g Consider two gases with the same molecular weight in containers of equal size. If the gases are at equal pressure, the gas at higher temperature will be [ Select ] dense. If the gases are at the same temperature, the gas at higher pressure will be [ Select ] dense. If two gases of different molecular weights are at the same pressure and temperature in containers of equal size, then the [ Select ] molecular weight gas will be more dense.

If the gases are at equal pressure, the gas at higher temperature will be less dense. If the gases are at the same temperature, the gas at higher pressure will be more dense. If two gases of different molecular weights are at the same pressure and temperature in containers of equal size, then the high molecular weight gas will be more dense.

Explanation:

The density of a gas decreases with increase in temperature at constant pressure. This is because, when a gas is heated, the kinetic energy of its molecules increases, the molecules move faster, bump into each other, and spread apart and therefore the volume of the gas increases. Since the gas molecules are now more spaced out, the density of the gas decreases.

The density of a gas has a direct relationship with pressure. The density of a gas increases with increases in pressure at constant temperature. This is because, when the pressure of a gas is increased, the space between the molecules decreases as they are forced to become more crowded together, as such the volume ofmthe gas decreases. The density of the gas will then increase.

The molecular weight of a gas is directly proportional to its density. Hence, gases of low molecular weight has lower densities while gases of high molecular weight have higher densities.

Hence, If the gases are at equal pressure, the gas at higher temperature will be less dense. If the gases are at the same temperature, the gas at higher pressure will be more dense. If two gases of different molecular weights are at the same pressure and temperature in containers of equal size, then the high molecular weight gas will be more dense.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
