What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
Does the molecules in a solid have motion or energy?
As temperature of a solid is increased, molecular motion increases.Since, temperature of a solid is directly proportional to average vibrational kinetic energy of molecules of a solid, therefore, energy of a solid increases with an increase in temperature. So, it demonstrates that molecular motion is directly proportional to energy i.e. the higher the energy of solid, the higher is the molecular motion.
What is the thermal energy of a substance?
the total energy from molecular motion.
What does Molecular Motion mean?
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
Does molecular motion stop when diffusion stops?
No molecular motion only ceases when the temperature is at absolute zero. The molecules have retained their kinetic energy although they are at equillibrium.

What happens to the kinetic energy of molecular motion in water when its temperature is increased?
When the water is heated, its molecules get additional kinetic energy due to it. This results in their increased velocity. As their kinetic energy gets increased, they try to overcome the force of attraction between themselves and eventually water changes into water vapour.

What is a thermal energy of a substance?
the total energy from molecular motion.
What is the thermal energy of a substance?
the total energy from molecular motion.
When a substace is heated how does the molecular motion change?
The average speed of the random molecular motion increases. The corresponding increase in molecular kinetic energy accounts for what happened to all of that heat energy.
Temperature is an indication of what?
Molecular motion / kinetic energy.
What is random molecular motion?
It is the unpredictable direction of motion, of which all directions have an equal probability.
What does Molecular Motion mean?
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
Is kinetic energy molecular energy?
the energy of a body or a system with respect to the motion of the body or of the particles in the system
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
Does molecular motion stop when diffusion stops?
No molecular motion only ceases when the temperature is at absolute zero. The molecules have retained their kinetic energy although they are at equillibrium.
