Atomic Theory and Matter and chemical reactions
Particle that all matter is made of
Atoms
A pH of 1-6 and contain more H+ ions is a
What is an acid
A push or pull
What is a force
This can be calculated using Work x Time and is measured in watts
What is power
Waves do not transfer any matter but ONLY this
What is energy
The 3 subatomic particles and their charges
what is electron (negative -)
neutron (no charge)
Proton (positive +)
A pH of 8-14 and having less H+ ions and more OH- ions is known as a
What is a base
For an object to move these kind of forces need to occur and in what direction would the object move
What are unbalanced forces and direction of the greater force
To move a heavy object into a truck what 2 simples machines should be used
Wheel and Axle and incline plane
Electricity is the flow of these subatomic particles
What are electrons
What the 3 phases of matter and their characteristics
Solid (definite shape and volume)
liquid (Not definite shape but definite volume)
Gas ( no definite shape or volume)
To separate a solution of sand, salt and water obtain from the ocean you would use the separation method of
What is filtration and evaporation
This law states that an object in motion will stay in motion and an object as rest will remain at rest unless acted upon by an unbalanced forced it is also know as the law off
What is the Law of inertia or Newton's 1st law
If the amount of work stays the same and the time decreases what happens to the power
What is increases
In electricity and magnetism like charges... and unlike charges...
What is repel and attract
What are the 5 indicators of a chemical change or reaction
Production of a gas
Production of a solid
Color change
change in temperature
Light Production
When a acid and base neutralize each these are produced
What is a salt and Water
This law states that F=ma or that the more mass an object has the more force needed to move it
What is Newton's 2nd Law
To make a lever easier to lift an object a person would
What is move the fulcrum closer to the load and increasing the distance the fulcrum is from the effort
When a wave bounces off a surface and returns to its original medium it is known as... and the two ray angles are
what is reflection and equal
This law states that energy is neither created or destroyed but transferred and that the total mass of the reactants is equal to the total mass of the products
What is law of conservation of Mass
In a solution there are two parts: the substance that is getting dissolved and the one doing the dissolving these are known as... ( state in correct order) and what 3 factors can be increased to increase the rate of solubility
What is the solute and Solvent
Temperature, surface area and agitation
This law states that for every action there is an equal or opposite reaction or that forces come in pairs
What is Newton's 3rd Law
For work to be done an object has to do these two things
Move a distance in a direction
To increase the strength of an electrical current or a magnetic field you such as in a electromagnet you would
What is increase the number of coils/loops or increases the diameter of the wire
