Which molecules has the most potential energy?

Kinetic energy is energy produced by motion/activity. Molecules become more active as they heat up. Therefore, molecules in a gaseous state would have the greatest kinetic energy.


Do molecules have the lowest average kinetic energy in a plasma?

No. Molecules have the lowest average kinetic energy in a solid. Plasma is the highest average kinetic energy.


How do molecules gain kinetic energy?

Heating increase the kinetic energy.


What is the measurement of the average kinetic energy of the molecules of a substance?

temperature is the average kinetic energy of a particle


What is the relationship between kinetic energy of molecules and their physical state?

The relationship between kinetic energy of molecules and their physical state is simple. The higher the kinetic energy the faster the molecules move. The fastest moving molecules are gaseous and the slowest moving molecules are solids.


The total kinetic and potential energy of the molecules of an object is know as?

The total kinetic and potential energy of the molecules of an object is thermal energy.


What is the average kinetic energy of all the molecules in an object is?

The average kinetic energy of all the molecules in an object is the temperature.


What is the measure of kinetic energy of the Molecules?

temperature is the measure of the average kinetic energy of a substances molecules, though energy is in joules and temperature is in Kelvin.

How does kinetic energy change with each state of matter?

When any substance goes from solid to liquid to gas, the kinetic energy of the molecules increases.Molecules in the gaseous state have the most kinetic energy.Molecules in the solid state have the least kinetic energy.


How does the average kinetic energy of a gas relate to its temperture?

The kinetic energy of a gas is the speed of motion of the gas molecules. The higher the speed of the molecules, the higher the kinetic energy and the higher the temperature.


The measure of the average kinetic energy of a group of molecules?

Temperature is the average kinetic energy
