Motion of Particles
The amount of force exerted over a certain area.
What is pressure?
The temperature at which a substance changes from a liquid to a gas.
***What is boiling point?
A rule termed by scientists to describe full stable outer shells in the second energy level of an atom.
What is the octet rule?
The phase of matter in which there is neither a fixed volume or a fixed shape.
What is gas?
Typically having a substance lose heat causes contraction and gaining heat causes expansion. This molecule is an exception.
What is water?
The measure of the average kinetic energy of the particles of a substance.
What is temperature?
The scientific term used to describe a gas turning into a solid due to loss of thermal energy.
What is deposition?
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?
The scientist who's periodic table became the foundation for the modern periodic table.
Who is Dimitri Mendeleev?
The most cohesive molecule among non-metallic molecules
What is water (H2O)?
The conversion of a substance from the solid to the gaseous state without the substance becoming a liquid.
What is sublimation?
Two conditions that are used to predict the phase of matter of a specific substance in a state diagram.
What is temperature and pressure?
The number of valence electrons in a neutral carbon atom (atomic number of carbon is 6).
What is 4?
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)?
An element responsible for making the planet Mars red and also your blood.
What is iron?
A silver-colored metal used in electronics that takes on a liquid state with normal human body temperature (37 degrees celsius).
What is gallium?
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?
The charge of an anion and the charge of a cation respectively.
What is negative and what is positive?
The property that describes how well one substance dissolves in another substance.
What is solubility?
The element that is responsible for the blue blood of octopuses, squid, and crabs.
What is copper?
The temperature and pressure scientists use as a specific set of standard conditions, also known as STP.
***What is 0 degrees celsius and 100kPa?
A chemical reaction that absorbs more energy from its surroundings than it releases.
What is an endothermic reaction?
The number of electrons needed to make a stable nitrogen atom (atomic number of nitrogen is 7).
***What is 3?
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?
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?
This allows gases to overcome the forces of intermolecular attractions.
What is kinetic energy?
A solid that does not have long-term order.
What is an amorphous solid?
The group of elements of the periodic table that do not bond to other elements and are un-reactive.
What are noble gases?
The density of an irregularly shaped object is 0.25 kg/ml. The object's mass is 10kg and when put into a graduated cylinder with 40ml of water the object changes the level of water to this # of ml.
What is 80ml?
The rarest, naturally occurring element in the earth's crust named after the Greek word "unstable".
What is astatine (chemical symbol At)?
