Kinetic Theory P1
Question | Answer |
---|---|
Describe the state of matter in a solid.(2) | •Strong forces of electrostatic attraction mean particles close together • Particles can only vibrate • Little energy |
Describe the state of matter in a liquid.(3) | • Particles slightly more disperse due to weaker attractive forces • Can flow • More energy than solids |
Describe the state of matter in a gas.(3) | • Particles move freely • More energy • No attractive forces |
What happens to the particles in a substance when heated? | They get more kinetic energy and move around more |
Define conduction. | The process by which heat energy is transferred by vibrating particles to neighbouring particles |
What is an insulator? | Substances where there are gaps in between particles, meaning heat energy cannot be transferred as quickly |
Why do metals conduct well? | Because they have free electrons that collide with each other and pass on energy quickly. |
