Physical Science Final Exam

Types of reactions are: Synthesis, Decompositions, Single Replacement, Double Replacement, Combustion

What are the properties of gas(in regards to shape and volume)?

When this type of force acts on an object, it accelerates

Iron combines with water and oxygen to form

Gold Foil Experiment

Occurs when one or more substances are changed into new substances that have new and different properties

A push or pull that acts on an object

The amount of matter in a given space or volume

A substance made up of atoms of two or more different elements joined by chemical bonds

The starting materials in a chemical formula

Reaction in which energy is released; feels warm; energy is released as a product

Not able to be divided

The four types of friction are: static, rolling, sliding, and solid

Particles in the nucleus that have no electrical charge

Atoms that have the same number of protons, but have different numbers of neutrons

The amount of space an object takes up

Newton's Third Law of Motion

A subatomic particle that has a negative charge

States that mass is neither created or destroyed in a chemical reaction

Are atoms that are no longer neutral because they have lost/gained electrons

Proposed that electrons move around the nucleus in certain paths or levels

Established his atomic theory in 1808. He did not "discover the atom".

Between a metal and a nonmetal where electrons are transferred

The ability of two or more substances to combine

How do you find the number of neutrons in an atom?

The centrally located tiny, extremely dense positively charged part of an atom (the center of an atom)

What is a pure substance?

Signs of a chemical change: change in color, change in odor, bubbling, production of cold, formation of a precipitate

Is a center-directed force that continuously changes the direction of an object to make it move in circle

The rate at which speed changes

Can be hammered into thin sheets; structurally manipulative

Temperature, Concentration, Surface Area, Stirring, and Catalysts

Ability to be drawn into wires

Is the product of an object's mass and velocity

Number written below and to the right of a chemical symbol in a formula

Anything that has mass and takes up space

Between a nonmetal and a nonmetal where electrons are shared

Newton's Second Law of Motion

Is the joining of atoms to form new substances

What is boiling point celcius?

The substance formed from a reaction

Gravitational force: Needs very massive objects to have noticeable effect, most effective for over short distances

Is a description of both speed and direction of motion (change of speed and direction)

What is freezing point celcius?

A particle with a positive charge & found in the nucleus of the atom

Branches of natural science:

The measure of gravitational force exerted on an object

Newton's First Law of Motion

Chocolate Chip Cookie Model

Computed for a particular instant

Energy is absorbed to the surroundings as heat; feels cold; goes from lower energy to higher

The overall force acting on an object after all the forces are combined

The movement of an object toward Earth solely because of gravity

A combination of two or more substances that are not chemically combined - they are physically combined

Is a force that acts between any two masses

The amount of matter in an object
