Is there a difference in the cfu/ml counts for the two treatment conditions

Heating kills most of the bacteria in the solution. Only some bacteria will survive whose temperature optima is higher, or are heat resistant.

Formula for calculating CFU/ml = no. of colonies * dilution factor / volume plated (in ml)

Suppose the number of colonies in normal solution plate comes out to be 300 and that in the heated solution plate comes to be 30, then cfu/ml for heated solution = 30*10^0/ 0.1 = 300 cfu/ml; and cfu/ml for normal solution = 3000cfu/ml

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.
