Mass & Volume
What is mass?
Mass is a measure of the amount of matter in an object.
What are electrons?
A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
Which do you think will fizz more when you open it, a can of warm soda or a can of cold soda?
A can of warm soda will fizz more because increasing the temperature decreases the solubility of a gas.
What is a solution?
A solution is a specific type of mixture where one substance is dissolved into another.
What is matter?
Matter is any substance that has mass and takes up space by having volume.
What is Volume?
The amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
What dose an atom has?
protons, neutrons, and electrons
What is an example of a Solution
One example of a solution is salt water which is a mixture of water and salt. You cannot see the salt and the salt and water will stay a solution if left alone.
What is a solution mixture?
A solution is a homogeneous mixture of two or more substances where one substance has dissolved the other.
Why do we need to study matter?
It's important for scientists to know the properties of matter because all things are made up of matter.
If the fruit were at a lower level than the iron object, what would be the mass of the fruit?
The mass of the fruit would be greater than 1 kg.
What microscope do we need to see an electron?
Transmission electron microscope.
If a solute is a solid or liquid, increasing the temperature increases its solubility. For example, more sugar can dissolve in hot water than in cold water?
If a solute is a gas, increasing the temperature decreases its solubility. For example, less carbon dioxide can dissolve in warm water than in cold water.
What is the definition of the solution?
The process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change. such a substance, as dissolved sugar or salt in solution.
What is matter made of?
All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons.
Can you see a beam of light when shining it through a true solution?
YES
Do electrons move?
No
When a solution reaches the point where it cannot dissolve any more solute what dose it turn in to?
It is considered "saturated."
What is a solution in a chemistry?
In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances.
Is air a matter?
Air is matter.
What is a mass and volume relationship?
Volume is the size of an object, and mass is its weight. To get density, divide mass by volume.
How much biger is electron then an atom?
They're about 100 million times bigger than electrons.
What an Saturated?
When a solution reaches the point where it cannot dissolve any more solute it is considered "saturated." If a saturated solution loses some solvent, then solid crystals of the solute will start to form. This is what happens when water evaporates and salt crystals begin to form.
What is a best definition of solution?
1a : an action or process of solving a problem. b : an answer to a problem : explanation specifically : a set of values of the variables that satisfies an equation.
Why does air matter but not light?
Air has mass and takes up space, while light does not.
