What is argon?
Argon is a noble gas element in Group 18 on the Periodic Table. Argon is colorless and odorless in the liquid and gas state.
What is oxygen gas?
Oxygen gas (also called elemental oxygen) is a molecule made of two atoms of oxygen connected by a double bond in which four electrons are being shared between the two atoms.
What is water?
Water is a molecule consisting of two atoms of hydrogen with each being bonded to one atom of oxygen.
What is the kinetic molecular theory?
The theory explains how the different states of matter are defined by the motion of the particles in each state.
What is temperature?
Temperature is defined as the average kinetic energy of the particles of a substance.
What is density?
Density is a measure of the compactness of a substance. Density is found by the following formula: Density = mass/ volume
What is a phase change?
A phase change involves the particles of a substance moving from one state of matter to another state of matter. An example of a phase change is a solid melting and turning into a liquid.
What is heat energy?
Heat is energy transferred from one object to another object due to a temperature difference between the two objects.
What is the Law of Conservation of Mass?
The law states that mass cannot be created or destroyed in an ordinary chemical reaction.
What are intramolecular forces?
Intramolecular forces (commonly called chemical bonds) are the forces that connect atoms together to form a molecule. These forces of attraction from strongest to weakest are metallic, ionic, polar covalent, and nonpolar covalent.
What are intermolecular forces?
Intermolecular forces are the forces of attraction between molecules. Atoms and ions can also exhibit these types of attractive forces. Intermolecular forces are much weaker than intramolecular forces. The forces from strongest to weakest are ion-dipole, hydrogen bonds, dipole-dipole, and London Dispersion.
What are van der Waals forces?
London dispersion and dipole-dipole forces are both types of van der Waals forces. The forces are generally attractive, but can become repulsive if the particles are moved too close together.
What are London Dispersion forces?
London dispersion forces are associated with nonpolar molecules, atoms, and noncharged molecules. Dipoles are induced within the atoms or molecules that make up the substance.
What are dipole-dipole forces?
Dipole-dipole forces are a type of van der Waals forces associated with molecules that have permanent dipoles. Dipoles are present in molecules that are polar and are due to a difference in electronegativity between the atoms that make up the molecule.
What is hydrogen bonding?
Hydrogen bonding is a special case of dipole-dipole attraction between hydrogen atoms and highly electronegative atoms, such as fluorine, oxygen, and nitrogen.
