Which statements describe how heat flows in foil? Check all that apply.
O Heat flows in all directions.
O Heat flows from left to right only.
The atoms on top of the foil absorb heat first.
O The atoms near the candle absorb heat first.
O Heat flows from the cooler atoms to the warmer
atoms.
O Heat flows from the warmer atoms to the cooler
atoms.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

distance, luminosity, brightness, radius, chemical composition, and temperature

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
