The amount of force exerted over a certain area.

What is pressure?

100

The temperature at which a substance changes from a liquid to a gas.

***What is boiling point?

100

A rule termed by scientists to describe full stable outer shells in the second energy level of an atom.

What is the octet rule?

100

The phase of matter in which there is neither a fixed volume or a fixed shape. 

What is gas?

100

Typically having a substance lose heat causes contraction and gaining heat causes expansion. This molecule is an exception.

What is water?

200

The measure of the average kinetic energy of the particles of a substance.

What is temperature?

200

The scientific term used to describe a gas turning into a solid due to loss of thermal energy.  

What is deposition?

200

The type of bonding that results from the attraction of oppositely charged ions and forms when there is a donor of electrons and an acceptor of electrons.

What is ionic bonding?

200

The scientist who's periodic table became the foundation for the modern periodic table.

Who is Dimitri Mendeleev?

200

The most cohesive molecule among non-metallic molecules 

What is water (H2O)?

300

The conversion of a substance from the solid to the gaseous state without the substance becoming a liquid.

What is sublimation?

300

Two conditions that are used to predict the phase of matter of a specific substance in a state diagram.

What is temperature and pressure?

300

The number of valence electrons in a neutral carbon  atom (atomic number of carbon is 6). 

What is 4?

300

A thin probed microscope built by Rohrer and Binnig that could produce and detect electric current and could detect the shape and surface of individual atoms.  

***What is the STM (scanning tunneling microscope)?

300

An element responsible for making the planet Mars red and also your blood.

What is iron?

400

A silver-colored metal used in electronics that takes on a liquid state with normal human body temperature (37 degrees celsius).

What is gallium?

400

The law that dictates conservation in chemical reactions. In 4Fe + 3O2 -> 2Fe2O3 for example, there are 4 Fe atoms in the products and reactants and 6 O atoms in the products and reactants.

What is the law of conservation of matter?

400

The charge of an anion and the charge of a cation respectively.

What is negative and what is positive?

400

The property that describes how well one substance dissolves in another substance.

What is solubility?

400

The element that is responsible for the blue blood of octopuses, squid, and crabs.

What is copper?

500

The temperature and pressure scientists use as a specific set of standard conditions, also known as STP.

***What is 0 degrees celsius and 100kPa?

500

A chemical reaction that absorbs more energy from its surroundings than it releases.

What is an endothermic reaction?

500

The number of electrons needed to make a stable nitrogen atom (atomic number of nitrogen is 7). 

***What is 3?

500

The property that explains how water drops bead up on a waxy surface, such as a leaf - when cohesion is stronger than adhesion.

What is surface tension?

500

The cooking and baking reaction which give cooked foods their brown color and their roasted or baked smells and flavors.

***What is the Maillard reaction?

600

This allows gases to overcome the forces of intermolecular attractions.

What is kinetic energy?

600

A solid that does not have long-term order.  

What is an amorphous solid?

600

The group of elements of the periodic table that do not bond to other elements and are un-reactive.
