the particle model and motion in gases Flashcards
what does the particle model of matter say
everything is made up of lots of tiny particles
what are the three states of matter
solids
liquid
gas
explain how particles are in solids
strong forces hold the particles together
they are in a fixed arrangement
the particles dont have much energy so they can only vibrate in their fixed position
explain how particles are in liquids
there are weaker forces if attraction between the particles but they can move past
eachother
they form irregular arrangements
they have more energy than particles in a solid so they move in random directions and speeds
explain how particles are in gases
there are almost no forces of attraction between particles
they have more energy than liquids and solids
they are free to move around and constantly going with random directions and speeds
what happens when gas particles collide
they exert a force
what happens if you increase the temperature of a gas
you transfer energy into kinetic energy store
what is the temp of gas related to
The average energy in the kinetic energy stores
What happened to hire the temperature of a gas
The higher the temperature the higher the average energy
What happens if you increase the temperature of a gas
The average speed of its Particles increase
