PS 5.1 and 2 Flashcard

Front

What is the most effective thermal conductor?

Back

Solid

Front

What is the thermal energy that is transformed from a material with a higher temperature to one with a lower temperature?

Back

Heat

Front

What does thermal energy represent in a system?

Back

The total energy of the particles in the system.

Front

What happens to the average kinetic energy of particles in an object when they begin to move quickly?

Back

The average kinetic energy increases.

Front

What happens to the temperature of an object when its particles' average kinetic energy increases?

Back

The object's temperature rises.

Front

What is a material that flows called?

Back

Fluid

Front

What is the relationship between temperature and kinetic energy in particles?

Back

As temperature increases, the average kinetic energy of the particles increases.

Front

What is the definition of thermal conductivity?

Back

The ability of a material to conduct heat.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows heat to flow easily, while an insulator resists heat flow.

Front

What is the term for the transfer of heat through direct contact?

Back

Conduction
