Yes. When substances are heated, they expand into liquids, gasses, or plasmas, and conversly, when cooled, they contract in the opposite manner. This is due to thermal properties of atomic structures. Heat causes an atom's electrons to reach higher orbits, and thus spread farther apart.

When the kinetic energy of atoms increases thermal energy increases or decreases?

Thermal energy (temperature) is the measurement of kinetic energy of atoms moving in a substance, therefore, as the speed (kinetic energy) of these atoms increases, thermal energy increases as well.


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.


What happens to the thermal energy of an object as temperature decreases as it increases?

it decreases because when an object is moving as the temperature decreases the object decreases


What happens to the thermal energy of a substance as its temperature increases?

When a sample of a substance absorbs thermal energy, its temperature rises.


What causes the particles of a substance to lose thermal energy?

The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.


What is the characteristic of matter that causes it to expand when the temperature increases and contract when the temperature decreases?

thermal expansion


What increases the?

The thermal vibration of the atoms in the material increases the resistance of that substance. The resistance is greatly depends on temperature.


What happens to the temperature of a substance when you prevent gain or loss of thermal energy?

If you define "thermal energy" as heat, and the "substance" is not affected by any energy that increases or decreases its temperature, by definition, nothing will happen to its temperature. If the substance reacts to electromagnetism, light or other radiation, it may increase or decrease its temperature, depending on the nature of the substance and its reaction to those energies. Note: See Discussion question.


During thermal expansion what happens to the density of a substance?

Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.


As the temperature of a substance increases its volume tends to increase due to what?

thermal expansion


What happens to mass when volume increases?

As the density of a substance increases the volume of a given mass of the substance decreases.


What happens to density during thermal contraction?

It increases. The volume of a material decreases in contraction, while the mass remains the same.
