Thermal Energy Flashcards
What are the four different ways thermal energy can be transferred?
- Radiation
- Convection
- Conduction
Describe the solid state of matter.
- Particles are tightly packed together in a regular pattern
- They have fixed positions
- Solids have a fixed volume
Describe the liquid state of matter.
- Particles are close together in an irregular pattern
- They can move past each other
- They have a fixed volume and take the shape of the container
Describe the gas state of matter.
- Particles are far away from each other
- Free to move around in random directions
- Gases take the volume of the container
What is conduction?
The transfer of thermal energy by collisions between vibrating particles
What determines the effectiveness of conduction?
The closer the particles are, the better the conduction
Which state of matter is the best conductor of thermal energy?
Solids
Which materials are considered the best conductors of thermal energy?
Metals due to free delocalized electrons

vibrating more
True or False: Thermal energy is transferred through solids primarily by conduction.
True
How is thermal energy transferred through conduction?
Through collisions between vibrating particles
