Molecules in a substance slow down when a substance is?
cooled. As temperature decreases, the kinetic energy of molecules decreases, causing them to move more slowly. This can lead to a decrease in the rate of chemical reactions and physical processes within the substance.
What is happening to the molecules of a substance when they are heated or cooled?
When a substance is heated, the molecules gain kinetic energy and move faster, causing them to vibrate and collide more frequently, which increases the temperature of the substance. When a substance is cooled, the molecules lose kinetic energy and move slower, reducing the frequency of collisions and vibrations, which lowers the temperature of the substance.
What happens to the kinetic energy of the particles in the substance during process condensation?
The average kinetic energy of the particles falls.
What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
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 happens to the kinetic energy of the particles in the substance during process condensation?
The average kinetic energy of the particles falls.
The kinetic energy of a substance is the what kinetic energy of its particles?
The kinetic energy of a substance is the average kinetic energy of its particles.
What is the kinetic energy of a substance and the kinetic energy of its particles?
The kinetic energy of a substance is the total energy associated with the movement of all its particles. The kinetic energy of individual particles is the energy due to their motion. The two are related, as the total kinetic energy of a substance is the sum of the kinetic energies of all its particles.
What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
When a substance is heated what happens to kinetic energy of particles?
When a substance is heated, the kinetic energy of its particles increases. This leads to the particles moving faster and colliding more frequently with each other and the container they are in.
When a substance is cooled down it usually expands true or false?
False. Most substances contract or shrink when they are cooled down because cooling reduces the kinetic energy of the particles in the substance, causing them to move closer together.
What happens to particles when materials are heated or cooled?
When materials are heated, the particles gain kinetic energy and move faster, leading to expansion of the material. Conversely, when materials are cooled, the particles lose kinetic energy and move slower, causing the material to contract or condense.
What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
