States of matter Flashcards
(25 cards)
describe the structure of solid?
describe the structure of solid:
- packed closely
- Can’t move
- small vibrations
- Stong force of attraction
describe the structure of liquid?
describe the structure of liquid:
- mostly touching
- can move over each other
- less dense
- little vibration
- less effective force of attraction
describe the structure of Gas?
describe the structure of gas?
- well separated
- move freely
- strong and high vibration
- almost no force of attraction
Which state of matter has the highest kinetic energy?
Which state of matter has the highest kinetic energy?
- Gases
what happens when a solid is heated?
what happens when a solid is heated?
- The particles will vibrate extremely fast so the force of attraction isn’t strong enough to hold them
solid to liquid? liquid to solid?
solid to liquid? liquid to solid?
- melting and freezing
liquid to gas? gas to liquid?
liquid to gas? gas to liquid?
- evaporation, boiling and condensing
solid to gas? gas to solid?
solid to gas? gas to solid?
- sublimation and deposition
solid to gas? gas to solid?
solid to gas? gas to solid?
- sublimation and deposition
example of a sublimation?
example of a sublimation?
- Carbon dioxide
how does evaporation happen?
how does evaporation happen?
- when the liquid particles move very fast on the surface of the liquid that it’ll overcome the force of attraction between the particles and break away to form the gas
What’s the substance’s temperature below its melting point?
What’s the substance’s temperature below its melting point?
- solid
What’s the substance above its melting point?
What’s the substance above its melting point?
- gas
What’s a substance between the melting point and boiling point?
What’s a substance between the melting point and boiling point?
- liquid
State if this statement is true or false?
- Each element has the same melting and boiling point with the room temperature
State if this statement is true or false?
Each element has the same melting and boiling point with the room temperature
- False
What’s diffusion?
What’s diffusion?
- the spreading out of particles where there’s a high concentration to low concentration
define a solvent?
define a solvent?
the solvent is a liquid substance that can dissolve on other substances
why will it take the particles in liquid less time to diffuse?
why will it take the particles in liquid less time to diffuse?
- because particles in a liquid move slower than gas
- particles in a liquid are closer together than gas so it’ll take more time
define a solution?
define a solution?
- which a liquid and solid substances dissolve together
How does making a solution form?
How does making a solution form?
- the attractive force between the partials in a solute is being broken down and the new attractive force is being formed
define a solute?
define a solute?
- is a solid substance that dissolves in a liquid
Define a saturated solution?
Define a saturated solution?
- when a solution contains the maximum amount of solute dissolved in a solvent, the solvent will have small solute particles down the cup, etc.
Define solubility?
Define solubility?
- ability of a substance to mix into a liquid
explain the difference between evaporation and boiling?
explain the difference between evaporation and boiling?
- Evaporation can happen at any temperature but boiling occurs at a certain tempreture
