What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
Why does the substances temperature stay the same when changing its state?
When matter is changing state the temperature remains constant because the energy being put into the process is being used to change the state of the matter, whereas when the matter is not changing state, the energy being put into the process is used to raise the temperature.
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.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
What is the measure of the kinetic energy of the particles of a substance?
Temperature is the measure of the average kinetic energy of the molecules in a substance.
Is the thermal energy that flows from one substance to another when the substances differ in temperature?
Yes, it is.
How is thermal energy of a substances related to its physical state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.
Does temperature have a higher amount of thermal energy in a substance?
The higher of the temperature of a substance, the more thermal energy it has.
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.
Can the temperature at which a substance melts is the same temperature at which it changes from liquid to solid?
Yes. Melting point is changing from a solid to liquid & freezing point is changing from a liquid to a solid. Both occur at the same temperature & these terms are usually used interchangably, although melting point is probably used more often than freezing point.
The movement of thermal energy from a substance at one temperature to a substance at a different temperature is called?
heat
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
Why does a substance's temperature increase when it receives more thermal energy?
Temperature is a measure of the concentration of thermal energy.
How is the themal energy of a substance?
The thermal energy of a substance is measured by its temperature.
How does a substance gain thermal energy?
substances can gain thermal energy by heating them or applying electric shocks
What is the movement of thermal energy from a substance at a high temperature to a substance at a lower temperature called?
Heat
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
