How does the speed of atoms in a substance related to its temperature?

If there is an increase in the temperature of a substance, that indicates the increase in vibration and speed of the particles. If there is a decrease in the temperature of a substance, that indicates the decrease in vibration and speed of the particles.


What happends to particles in a substance when it is heated or cooled?

An increase in the temperature of a substance is an increase in the average energy of the particles. They move faster.


How does the motion of particles in an object change when the temperature increases?

The average speed of the particles increasesTemperature is a measure of the average speed of particles in a substance. If you increase the temperature of the substance, then the average speed of the particles in the substance increases.


How is the temperature of a gaseous substance related to the average kinetic energy of the particles in the substance?

if the temperature of the substance is raised then the kinetic energy of the gaseous particles will also increase....


The temperature of a substance increases when the?

The temperature of a substance is said to increase when the average kinetic energy of the constituent particles increases.


What is the meaning of kinetic energy?

Kinetic energy of a substance is the energy of motion of its particles. Temperature is a measure of this quality. When you increase the kinetic energy of a substance, you increase the motion and collisions between its particles, and its temperature goes up.


How does kinetic energy affect the movement of particles?

The higher the kinetic energy (temperature), the higher the velocity. An increase in temperature thus causes the particles of a substance to move faster.


How does an increase in the total energy of the particles in a substance affect the thermal energy of the substance?

How does an increase in the total energy of the particles in a substance affect the thermal energy of the substance.


What happens to the speed of particles when the temperature heats up?

The speed of particles increase when temperature increase.


What is a definition of an expansion in chemistry?

an increase in the volume of a substance while its mass remains the same . expansion is usually takes place due to increase in temperature , when substance is heated the molecular bond between the particles are weakened , the particles move faster, causing the substance to expand


How can you add thermal energy to a substance without increasing temperature?

If the substance's temperature doesn't increase, it must be undergoing a phase change - such as when ice melts. In that case, the thermal energy is used up to increase the potential energy of the individual particles.


How does the volume of matter change with an increase in temperature?

In most cases, the volume will increase with temperature... density decreases. The volume of liquids and gasses increase as they are heated. This is because the heat energy is tranferred to the particles in the substance, making them increase their speed. The particles then need more space to move, so there becomes more space around the gas or liquid particles causing the substance expand and take up more space.


What do you add to kinetic energy to increase heat?

This doesn't really make sense. If you apply heat to a substance you increase the kinetic energy of its particles, which we perceive as an increase in temperature.


How does temperature or heat energy affect particle movement?

Temperature is a measure of particle movement. An increase of temperature, in a sense is an increase of the average movement of the particles within the substance, to include vibrations, spins, and lateral movement.


What happens to particles as the temperature increases?

As the temperature of a substance increases, its molecules move faster and therefore take up more space. This generally causes a substance to increase in volume when heated.


What happens to the temperature increase the number of particles what happens to the pressure?

Increasing the temperature the number of particles remain constant and the pressure increase.


When the temperature increases the kinetic energy of the particles decreases?

No. In gases, 'Absolute temperature' is proportionally related to the kinetic energy of the particles. Therefore, increase in temperature results in increase in the kinetic energy of the particles.


Why the solubility increase with temperature?

because the increase of the motion of the particles


How do particles of matter react to an increase in temperature?

When there is an increase in an object or medium's temperature, its particles have increase kinetic energy. Temperature is the measure of the average amount of kinetic energy within an object or medium.


What would increase temperature of a substance?

When a substance is heated the temperature is increased. This occurs because energy enters the substance which will increase the kinetic energy of the molecules,thus causing a rise in temperature.



How is heat energy created?

heat energy is created by the random motion of the particles present in the molecules of the substance which increases the kinetic energy as a result of increase of velocity of intermolecular particles resulting in increase of temperature and producyion of heat.


Could the temperature of a material increases the average of its particles also increase?

If the temperature of a material increases, the average kinetic energy of its particles will increase.



Why does an increase in temperature increase the rate of diffusion of substances into or out of cells?

An increase in temperature results in an increase in the speed at which particles are moving. In return, the high speed of moving particles lead to an increased rate of diffusion.
