Which has more thermal energy? Burning log or an ice cube?
Burning log
Give me an example of kinetic energy.
Moving energy.
Stored Energy
Potential Energy
In a convection current, heat ____________. (rises or sinks?)
Rises
Does something that is hot have more thermal energy than something that is cold? Yes or no?
Yes
Give me an example of potential energy.
Stored energy. No movement.
What is another word for heat energy?
Thermal Energy
What is the transfer of thermal energy due to direct contact?
Conduction
The faster the particles move,
Hotter they get. More kinetic and thermal energy they have.
When there is not enough _____________, change in the substance cannot occur.
energy
The energy of the motion of the particles in the matter
Total internal energy
What is the transfer of heat by electromagnetic waves?
Radiation
How does thermal energy move between two objects of different temperatures? Cold to hot? Hot to cold?
Hot to cold.
_____________ is a measurement of the average kinetic energy of the particles in an object.
Temperature
The sum of potential energy and kinetic energy
Total internal energy
What is the transfer of thermal energy by movement of warmer and cooler liquids and gases?
Convection
Heat will continue to travel until objects ___________
are the same temperature.
________________ occurs when an object’s energy moves from potential energy to kinetic energy.
