The addition or loss of thermal energy changes the arrangement of the particles during?
a change of state
What is due to the random motion of particles?
Thermal Energy
What is the energy of moving particles that produce heat?
thermal energy
What is a measure of the energy of the particles in an object?
Thermal, or heat, energy.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
The addition or loss of thermal energy changes the arrangement of the particles during?
a change of state
What type of energy is primarily associated with the random motion and arrangement of the particles in a substance?
Thermal Energy
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 happens to the particles of a solid as it becomes a liquid?
Particles of a liquid have more thermal energy than particles of the same substance in solid form. As a gas, the particles of this same substance have even more thermal energy. A substance changes state when its thermal energy increases or decreases sufficiently. A change from solid to liquid involves an increase in thermal energy. As you can guess, a change from liquid to solid is just the opposite: It involves a decrease in thermal energy.
Is melting thermal energy or movement in particles?
Thermal
What is the difference between heat and thermal energy?
Heat is thermal energy flowing from particles of one object to particles of another object. Thermal energy is the type of energy of moving particles in an object
Which describes a physical change that results from the addition of thermal energy?
Expansion (either of a solid or steam) and evaporation are two of these physical changes.
Does temperature contain any particles?
Temperature is a measure of the thermal energy of a system...thermal energy cannot be said to be a particle, but particles may have thermal energy.
How does thermal energy affect kinetic energy of particles?
Thermal energy is the average kinetic energy of all particles in a substance.
What happens to the particles in matter when thermal energy is added?
When thermal energy is added to particles of matter, it causes the particles to move faster and emit more energy.
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.
Define thermal energy?
Thermal Energy: Substance that has energy from the movement of its particles.
