What is a form of energy caused by increased molecular activity and is a measure of the total energy of the substance?
The form of energy caused by increased molecular activity is called thermal energy. It is a measure of the total kinetic and potential energy of the molecules in a substance due to their motion and vibration. Thermal energy determines the temperature of a substance.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
When an object gains thermal energy, the motion of its molecules increases, leading to faster movement and higher kinetic energy. This can result in the object heating up. Conversely, when an object loses thermal energy, the motion of its molecules decreases, leading to slower movement and lower kinetic energy, resulting in the object cooling down.
How does adding heat affect molecular motion?
Adding heat increases the kinetic energy of molecules, causing them to move faster and more randomly. This increased molecular motion can lead to changes in the physical state of matter, such as melting a solid into a liquid or vaporizing a liquid into a gas.
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 happens to temperature if the average motion of particles is increased?
If the average motion of particles is increased, the temperature of the substance will also increase. This is because temperature is directly related to the average kinetic energy of the particles in a substance. As particles move faster, they have more kinetic energy and thus the temperature rises.

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?
Thermal energy of a substance is the internal energy associated with the random motion of its atoms and molecules. It is a measure of the total kinetic energy of the particles within the substance.
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?
Random molecular motion refers to the constant, unpredictable movement of molecules due to their thermal energy. This motion occurs in all substances, and the speed and direction of the molecules change rapidly as they collide with each other and their surroundings. It is this random motion that contributes to various macroscopic properties of matter, such as diffusion and viscosity.
What does Molecular Motion mean?
Molecular motion refers to the movement of molecules in a substance, which is manifested through various forms like translation, rotation, and vibration. This motion is driven by factors such as temperature and energy, and it affects the physical properties and behavior of substances. Understanding molecular motion is crucial in fields like chemistry and physics for explaining phenomena like diffusion and phase transitions.
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?
A substance that absorbs energy may become hot, undergo a phase change, or emit light depending on the absorbed energy.
Does molecular motion stop when diffusion stops?
No, molecular motion does not stop when diffusion stops. Molecular motion refers to the movement of molecules within a substance, which continues even when there is no net movement of molecules from one region to another (diffusion).
