1a. States Of Matter Flashcards
What are the states of matter?
Solid, Liquid, Gas
What is solvent?
Substance, ordinarily a liquid, in which other materials dissolve to form a solution
What is solute?
The substance that dissolves in a solvent to produce a homogeneous mixture
What is solution?
A homogeneous mixture of one or more solutes dissolved in a solvent
What is solubility?
The maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature
What is saturated solution?
a solution in which the maximum amount of solvent has been dissolved
What is the properties of a solid’s volume and shape?
The volume of a solid is fixed and the shape of a solid is fixed
What is the properties of a liquid’s shape and volume?
The volume of a liquid is fixed and the shape of the liquid take the shape of the container
What is the properties of gas’s volume and shape?
The volume of a gas is not fixed and the shape of the gas is not fixed.
What is melting?
Melting is when a solid is heated and becomes a liquid
What is evaporation?
Evaporation is when liquid is heated and becomes gas
What is sublimation?
Sublimation is when solid is heated and it becomes a gas
What is solidification?
Solidification is when liquid is cooled down and it becomes a solid
What is condensation?
Condensation is when gas is cooled down and it becomes a liquid
What is deposition?
Deposition is when gas is cooled down and it becomes a solid.
Is heat absorbed or released by these processes: condensation, solidification and deposition?
Heat is released
Is heat released or absorbed in these processes: evaporation, melting, sublimation
Heat is absorbed
What happens at melting point?
Melting is when the strong forces of attraction holding the particles together are broken
What happens when liquid evaporating?
Liquid evaporating is when a few particles gain enough energy to escape as a gas
What happens to the particles when they are a solid and is being heated up?
Solid - as the temperature rises, the particles begin to vibrate.
What happens to the particles when a liquid is being heated up?
Liquid - the forces of attraction are constantly being broken and formed, leading to a less orderly arrangement of particles than in the solid phase.
What happens to the particles when the liquid is boiling?
The forces of attraction between teh particles are completely broken and the particles escape as gas.
What happens to teh particles when it is above the boiling point?
There is no liquid left. The particles in teh gaseous phase are moving completely randomly and are the least ordinary in their arrangement.
What happens to the particles inside a solid?
Particles packed closely, vibrating slightly. A very orderly arrangement held together by the forces between the particles.
Why is plasma sometimes considered as the 4th state of matter?
Plasma is a form of matter. It is when electrons wander round freely amount the nuclei of the atoms
What is the name of the transition between ice and water?
Melting
What is the name of the transition between water and steam?
Evaporation.
