States of Matter
name 3 states of matter.
solid, gas and liquid
What is a Solute?
A Solute is a substance that is dissolved in a solution
What is a mixture?
A mixture is a type of substance that contains more than one substance and particle.
what is concentration?
the quantity of a Solute in a solution
what is the particle Theory?
an explanation of why matter which is made up of particles behaves the way it does.
Is air considered matter?
Yes, because it has mass and takes up space.
What is a Solvent?
A Solvent is a substance that is dissolving a solute.
What are the two types of mixtures?
Heterogeneous and Homogeneous
how do you make substance dissolved faster
you add heat
explain the way the particles act in solids, liquids, and gasses.
Liquids take the space of their container the particles are loose. Solids have a fixed shape and the particles are tightly packed but still have space between them. Gasses will take all space.
What happens to particles when matter is heated?
Heating gives particles more energy and makes them move faster.
In saltwater which one is the Solute?
Salt
Definition of a homogeneous mixture and give an example
Homogeneous is uniform with two or more substances and you cannot tell the ingredients.
E.G apple juice, hot chocolate, Gatorade, maple syrup.
give three examples of substances that dissolve in water.
sugar, salt and soap
Describe the particles in a solid.
The particles in a solid are very tightly packed together but they are still moving.
What is the name of the change when a solid turns to gas?
sublimation
What happens to solute particles when they dissolve?
They separate and spread among the solvent particles.
Definition of a heterogeneous mixture and give an example
A heterogeneous mixture is where the composition is not uniform and mechanical you are able to take apart the ingredients.
what is concentration
it is the quantity for a solute in a solution
What are the five major points of particle Theory?
All matter is made up of tiny particles
the 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. Different substances are made of different particles
What happens to particles when a solid melts?
The particles move faster and spread apart, so the substance will change into a liquid.
What do you call a solution when it cannot dissolve anymore substances?
A saturated solution
Sugar is dissolved completely in water, why is this still a mixture and not a pure substance?
It's still a mixture because sugar particles are mixed with water and can be separated by evaporation.
what is water purification?
Water purification is a strategy that uses filters/filtration to extract bacteria from water so households can purchase clean water.
Ice melts into water when heated, explain what happens to particles during this.
When ice melts while being heated, particles gain energy and move faster
