Physical Science Review

This scientific theory states all matter is composed of discrete units called atoms.

The Law of Gravitation states objects are attracted to each other based on

Based on Newtonian physics, this is the term meaning the "amount of matter in a substance".

A solution is a homogenous mixture composed of a solute and what?

Elements within the same period on the periodic table have similar chemical properties.

In this state of matter, the molecules comprising the substance form a crystal-like lattice.

The condition of being where [H⁺] = [OH^-]...pure water is an example of this.

The Periodic Table is a visual representation of the 118 known elements. Who designed it?

A combination of two or more pure substances where each pure substance retains its properties.

Which of the following is most likely an indicator of a chemical change?

Groups of elements are arranged vertically and share characteristics. Which is the most stable?

The negatively charged subatomic particle orbits the nucleus within this region.

Why is cooking an egg a chemical change?

As H2O increases in temperature it goes from solid to liquid to gas. These are the 3 primary

What's the name of the thingymadoo in the picture below?

In chemistry, a salt results from what kind of reaction between an acid and a base?

One of the definitions of this type of chemical substance simply states it is a proton donor.

Which of the following is an example of a strong base?

TRUE or FALSE: A homogenous mixture has the same uniform appearance and composition throughout.

The state of matter where a substance expands indefinitely to fill its container.

The smallest sub-unit on the Periodic Table; Mercury, Uranium, and Neptunium are examples.

Varying the number of neutrons within the nucleus of an atom results in what type of particle?

A perpetual motion machine, one that produces work without energetic input, can't exist because

This law states, "mass of a closed system must remain constant over time".

The quantity of three-dimensional space enclosed by some closed boundary is

Force vectors point in the direction of force applied. Where does the net force vector point?

This subatomic particle resides in the nucleus, has a positive charge, and a mass of ~1 A.M.U.

In this state of matter volume is defined but shape is not.

What is the name of the force exerted between any two physical bodies containing mass?

Speaking of Krypton, what is its atomic number? How many protons are in its nucleus?

The electromagnetic spectrum ranges from gamma rays to radio waves. Which are more energetic?

This is the equivalent of the masses of all protons, neutrons, & electrons comprising an atom.

Which of the following forms of frictional forces has the highest relative values?

Which of the following is NOT an example of physical change?

What is the name of the force perpendicular to the plane an object is resting on?

This is a type of mixture where the substances remain physically separate.

Think of a solution of pure saltwater. What is the solute and what is the solvent?

The name of the atomic center where the protons and neutrons are located.

TRUE or FALSE: An object's weight is directly dependent on the force of gravity it experiences.

This property of matter is defined as being a substance's mass per unit volume.
