Question

substance which have greatest average kinetic energy is ?​

Answer 1

Gas atoms and gas molecules have greatest average kinetic energy...

Answer 2

Answer:

Gas molecules and atoms have the highest average kinetic energy.

Explanation:

At a specific temperature, polyatomic gas molecules also have the highest average kinetic energy. The highest kinetic energy molecules are those in the gaseous state, while the lowest kinetic energy molecules are those in the solid state. The average kinetic energy of the molecules is measured by the temperature. The relationship between the molecules' average kinetic energy and Kelvin temperature is direct. The greatest average kinetic energy formula is 12mv2=kT, where k is a constant of proportionality. The velocity v must be constant if the temperature T and molecule mass m are both constant. Water molecules have more kinetic energy at 10°C because the intermolecular forces are weaker than in metals like steel, copper, and mercury.

Thus, the average kinetic energy of a gas molecule is calculated as the product of each gas molecule's half mass and its RMS speed squared.
