Solids, Liquids and Gases Flashcards
What are the properties of a liquid?
- some force of attraction between particles.
- don’t have a definite shape (take the shape of the container.)
- quite dense.
- can flow past each other (particles)
What are the properties of a gas?
- very weak forces of attraction between particles.
- particles collide with each other and the walls of the container.
- can be compressed.
- low density
What is the melting point?
The temperature at which a solid becomes a liquid.
What is the boiling point?
The temperature at which a liquid turns into a gas.
What is sublimation?
A solid to a gas skipping liquid stage.
What is freezing?
Liquid to solid.
What is melting?
Solid to liquid.
What is boiling?
Liquid to gas
What is condensing?
Gas to liquid.
What can cause gas pressure?
-Heating the gas to give the particles energy, making the particle movement quicker, gaining kinetic energy and colliding with the edge of the container and other particles.
What other thing can cause gas pressure?
-by lowering the volume (container,) this way more particles are in a smaller volume causing them to collide with the walls of the container and other particles because there are more particles and less space.
What is the properties of a solid?
- strong forces of attraction between particles.
- fixed position
- can vibrate but cannot flow past each other (particles)
- definite shape and volume.
- usually dense
