State Changes If you give the particles energy; or take energy away from them; then you can change their state. If you heat up a solid - you give it some energy. This causes the particles to move more and the solid to change into a liquid, or melt. If the liquid is heated then it may evaporate and turn into a gas.

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 is the relationship between the temperature of and object and the motion of it's particles?
The faster the particles move- then the more energy they have, then the warmer the object will be.
What is the relationship between friction and thermal energy?
When temperature increases, particles in an object speed up, which means an increase in thermal energy. Since the particles are moving more now, the potential energy decreases, therefore kinetic energy increases. Overall, when temp goes up, thermal energy goes up, which leads to an increase in kinetic energy.
Describe the connection between kinetic energy and the movement of particles in a substance?
If an object moves, it has kinetic energy. The same applies to particles.
What is the energy transfer between particles as they collide within a substance or between two objects in contact called?
Heat: the transfer of energy from the particles of a warmer object to the particles of a cooler object. (Source: Nelson Science and Technology Grade 7 Textbook, page 186.)
When temperature increases the kinetic energy of the particles decreases?
Kinetic energy is directly related to temperature, because temperature is the average kinetic energy of an object. Therefore, as the temperature of an object decreases, its kinetic energy decreases, as well.

If an object moves, it has kinetic energy. The same applies to particles.
The thermal energy of an object is?
The total kinetic and potential energy of its particles.

Heat: the transfer of energy from the particles of a warmer object to the particles of a cooler object. (Source: Nelson Science and Technology Grade 7 Textbook, page 186.)
Is the kinetic energy of a substance the kinetic energy of its particles?
No. The average kinetic energy of the individual particles in an object is basically related to the object's temperature.
When the temperature of a substance decreases increases what happens?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
What happens to the particles when an object cools?
When an object cools, the particles' kinetic energy transfers back into potential energy, the particles slow down.
When negative work is done on a moving object it's kenetic energy?
When negative work is done on the object, the object's energy decreases. This MAY be kinetic energy, but some other form of energy may increase instead, for example, potential energy or heat energy.
Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.
