What is the average kinetic energy of any substance at 0 k? j

a.) 0
b.) -273
c.) 273

A) 0

the average kinetic energy of any substance at 0 K is 0 J

Explanation:

Kinetic energy is essentially the energy associated with motion. Based on the kinetic molecular theory, average kinetic energy of particles is directly proportional to its temperature. Mathematically, this is expressed as:

where R = gas constant = 8.314 J/mol-K

T = temperature in Kelvin

Based on the above equation, as temperature increases so does the average KE and vice-versa

At T = 0 K, KE = 0

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.
