(275) Chemical and Physical Processes

Chemical Process

A process that involves breaking and forming bonds, resulting in a change in the chemical composition of substances.

Physical Process

A process that involves changes in state or appearance without altering the chemical composition of substances.

Intermolecular Forces

Forces that occur between molecules, such as dipole-dipole forces and induced dipole forces.

Intramolecular Forces

Forces that occur within a molecule, including covalent and ionic bonds.

Change of State

A transition between solid, liquid, and gas phases, typically associated with physical processes.

Combustion of Methane

A chemical process where methane reacts with oxygen, breaking covalent bonds and producing changes in color, odor, gas, heat, or precipitate.

Ionic Compound Dissolution

The process of an ionic compound, like sodium chloride, dissolving in water, which can be viewed as either a physical or chemical process depending on the perspective.

Hydrogen Bonds

A type of intermolecular force that occurs between water molecules, significant in the boiling process of water.

Dipole

A molecule that has a positive and a negative end, such as water, which influences the behavior of ions in solution.

Sodium Ion

A positively charged ion (Na+) that interacts with the negative portion of a water molecule during dissolution.
