Whats a physical property?

Characteristics that can be observed with out changing the objects composition.

100

Tell me the four states of matter.

Liquid, gas, solid and plasma

100

Tell me two characteristics of a Proton.


  • Part of the Nucleus.

  • Positive charge.

What is a substance?

A substance is a type of matter that can't vary in composition.

200

Whats flamability? 

Ability of a material to burn easily/

Tell me the definition of a physical change and an example.

A change that dosnt alter the identity of a substance.

Exp

Cutting paper.

Give me three characteristics of an element.

1. Has only one type of atom.

2. Has a chemical symbol.

3. Is organized in the periodic table.

300

What's a chemical change?

A change that alters the identity of a substance or creates a new one with new properties.

Mass and Volume

300

Tell me three characteristics of a liquid


  • Takes the shape of its container.

  • Particles kind of close together.

  • Particles free to move

300

How do you calculate the electrons?

It is normally the same as the proton.

400

Tell me two characteristics of a compound?

1. Has 2 or more atoms.

2. Has a chemical formula.

400

Its rusting a chemical change?

Yes, Cause it creates a new material cause of the reaction between the oxygen and the metal.

400

What's density and how do you calculate it?

Its the mass per unit of volume. The equation is 

Density=Mass/Volume

400

Tell me three characteritics of a Gas.


  • Particles very apart.

  • Particles move freely.

  • Very weak attractive force.

400

How do you calculate the neutron in an atom?

Neutrons=Atomic Mass Number−Atomic Number

Tell me the 2 types of mixtures and three characteristics of each.

Heterogenous 

1. Unevenly mixed.

2. Can be physically separated.

3. Visibly mixed.

Homogeneous 

1. Evenly mixed.

2. Cannot be seen.

3. Can only be separated by chemical methods.

Tell me 5 signs of chemical change.

1. Change of color.

2. Smoke.

3. Fizz.

4. Bubbles

5. Energy change.

6. Explosions

7. Precipitation

Tell me three physical properties and theire definition.

  • Mass
    • The amount of matter an object has.

    • Weight depends.

  • Volume       size dependent

    • You can measure the volume of a liquid with a measuring cup.

    • You can measure the volume of a solid with a special formula.

  • Conductivity

    • Ability of a substance to transfer either heat or electric currents.

  • State of matter

    • Whether something is a liquid solid or gas.

  • Magnetism 

    • Attractive force some metals especially iron.

  • Density

    • It is the mass per unit volume of a substance.

    • Does not matter the volume of the object.

    • It's helpful when identifying a new substance.

  • Solubility

    • Is the ability to dissolve a component in another.

  • Melting Point

    • The temperature in which a solid turn into a liquid.

  • Boiling Point

    • The temperature in which a liquid turns into a gas.

500

What's conservation of mass?

During physical change properties of matter change. The particles in matter that are present before a physical change are the same as those present after the physical change. Because the particles are the same both before and after a physical change the mass before and after the change is the same.
