Particle Theory and States of Matter Flashcards
What are the 3 states of matter?
Solid, Liquid and Gas
What is the structure of particles in a solid?
Strong forces of attraction hold the particles together in a lattice structure
What is the movement of particles in a solid?
Vibrating at a fixed point
What happens when we heat up a solid, what can this do?
When we heat up a solid, the particles vibrate more which weakens the attraction between them. At a certain temperature called the “Melting Point”, the attraction will weaken to the point where the particles break free of their bond and melts into a liquid.
What happens if we now increase the temperature of a liquid?
The increased energy from the heat causes particles to vibrate more and weaken the force of attraction and break the bond of the particles boiling the liquid into a gas. This is called the Boiling Point
Describe the properties of a gas
They do not have a definite shape or volume and are free to move due to the weak force of attraction between the particles
What happens to the container if we increase the temperature of a gas which is inside the container?
If the volume of the shape is fixed, the pressure will increase, if it’s not fixed, the volume will expand (blowing a balloon)
Gas to Liquid Transformation name
Condensation
Liquid to Gas Transformation name
Solidification
