Drag the tiles to the boxes to form correct pairs. As our current atmosphere formed, the concentrations of various atmospheric gases fluctuated. Match each gas with the explanation that best describes how its proportion changed during the evolution of the atmosphere.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

answer; /// i believe the correct answer is (reactants);
