Changing states
What is it called when a liquid turns into a gas?
Evaporation.
What is the particle theory of matter?
It is the explanation of why particles behave the way they do.
What are the two different types of mixtures?
Heterogeneous mixtures and homogeneous mixtures.
What is a pure substance?
It is when a solid, liquid or gas only has one type of particle.
What is the universal solvent?
Water.
What is it called when a solid changes to a gas?
Sublimation.
What happens when you heat up an atom vs when you cool down an atom?
When you heat up an atom, it moves faster and when you cool down an atom, it moves slower.
What is the difference between a heterogeneous mixture and a homogeneous mixture?
A heterogeneous mixture is not uniform and a homogeneous mixture is uniform.
What are the two different types of pure substances?
Element and compound.
What is it called when something can not be absorbed anymore?
Saturation.
What are is the difference of the particles in a solid, liquid and gas?
Name the parts of an atom.
Orbit, proton, neutron, electron, nucleus.
True or false- mixtures can be a gas.
True.
Finish the sentence- copper, zinc, gold, iron and uranium are parts of...
The periodic table.
What is a solvent and a solute?
The solute is the thing dissolving and the solvent is the thing doing the dissolving.
Name all the changing states.
Melting, freezing, evaporation, condensation, sublimation, and deposition.
Finish the sentence- matter can be defined as anything that...
Has mass and takes up space.
Name two things that solutions and mechanical mixtures share.
Pure substances, particles, 2 or more substances, mixture, usable.
List five heterogeneous mixtures.
Fruit salad, pizza, soil, trail mix, cookie dough (chocolate chips) sandwich, tacos, cereal (milk), quesadillas
2. filtration to remove sand
3. evaporate the water and your left with salt
An icicle melts into water then what happens?
It evaporates.
Name the five major points of particle theory.
All matter is made up of tiny particles. All particles are always moving. There is space between all particles. Adding heat makes particles move faster. All particles in a pure substance are the same and different substances are made up of different particles.
How many particles can be in a mixture?
Infinite.
How many elements on the periodic table are pure substances? (number answer)
118.
Name five things that the universal solvent can dissolve.
Salt, soap, sugar, cinnamon, brown sugar, alcohol and acids.
