Heating And Cooling Curves Flashcards
Melting point meaning.
When a solid heats up, the solid particles gets energy and vibrates faster and faster. Until the particle force breaks one by one, and turns into a liquid. Melts at around 17 degrees.
Boiling point meaning.
The liquid is hot and gets energy and vibrates then breaks the force and then turns into a gas. Boils at around 115 degrees.
Condensing meaning.
When a gas is cold and turns to a liquid.
Freezing point meaning.
The temperature when a liquid turns into a solid when cooled.
Distillation meaning?
Distillation is a way of separating mixtures with different boiling points by using heating and cooling.
What are the 2 types of distillations?
Simple distillation
Fractional distillation
What’s simple distillation?
Can be used to separate solutions from the boiling points.
What’s fractional distillation ?
Can be separated mixture of liquid to their different boiling points.
Floatation ?
To separate small particles of a solid by their different capacities to float.
Chromatography?
Separation of a mixture by passing it in solution through a medium in which the components move at different rate.
Magnetism?
Separate mixtures by using magnet to attractive magnet.
Filtration?
Separate solid from a liquid.
Extraction?
Separate liquid / liquid, liquid/solid, acid/base.
Crystallization?
Process when solid forms, where atom and molecules are highly organized into a structure.
