The atoms and molecules in a gas are in constant motion. temperature is a measure of their speed as they move. how are these related? (2 points) as temperature decreases, the molecules and atoms move faster. as temperature decreases, the molecules and atoms move at the same speed. as temperature increases, the atoms and molecules move more slowly. as temperature increases, the molecules and atoms move faster. atoms and molecules always move at the same speed regardless of any temperature change.

As temperature increases, the molecules and atoms move faster.

According to the Kinetic Molecular Theory of gases, the average kinetic energy (KE) of the molecules is proportional to the Kelvin temperature.

KE = ½ mv²

Thus, if T increases, KE increases and so does the speed (v) of the particles.

they are both synthetic elements

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
