Chapter 5 Thermal Effects Flashcards
1
Q
What is the kinetic theory?
A
A theory where matter is made of tiny particles which are always in motion
2
Q
How do particles behave in a solid?
A
They are close, have strong attractions and vibrate on the spot without moving
3
Q
How do particles behave in a liquid?
A
They are close together, attract each other, but can move past each other
4
Q
How do particles behave in a gas?
A
They are far apart, essentially free of attractions and move at high speeds
5
Q
What are the particles of kinetic theory?
A
Sometimes atoms, but most of the time molecules (groups of atoms)
6
Q
What is Brownian Motion?
A
The random movement of tiny objects like ash droplets caused by collisions with particles in a liquid or gas
