the atoms and molecules in a gas are in constant motion. temperature is a measure of this motion. how are these related?

as temperature increases, the molecules and atoms move faster.
as temperature decreases, the molecules and atoms move farther apart.
as temperature increases, the atoms and molecules move closer together.
as temperature decreases, the molecules and atoms move faster.

As temperature increases, the molecules and atoms move faster.

Explanation:

Molecules and atoms move according to how hot or cold the temperature is. As the temperature rises, the molecules and atoms will begin to move faster. As the temperature cools, the molecules and atoms will begin to move slower.

Hope this helps! :)

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
