IB Chemistry S1.1 Definitions
This page contains our IB Chemistry definitions for S1.1. By learning each one of these definitions, you will fully cover the content for IB Chemistry 'Particulate matter'.
boiling
A liquid absorbing heat to turn into a gas. Boiling can occur randomly from a liquid's surface.
chemical reaction
A reaction that forms new substance(s) by breaking bonds in the reactants and forming bonds in the products, causing an energy change in the system but preserving mass and particles
compound
A substance made up of two or more atoms chemically bonded in fixed ratios and have different properties than their components
condensation
A gas losing heat to turn into a liquid
deposition
A gas that loses enough heat to instantly turn into a solid
element
Simplest substance made from atoms that cannot be broken down
evaporation
A liquid absorbing heat to turn into a gas. Evaporation can occur randomly from a liquid's surface. Synonym for boiling and vaporization.
freezing
A liquid losing heat to turn into a solid
heterogeneous mixture
A mixture wherein the components are in different states of matter
homogeneous mixture
A mixture wherein the components are the same state of matter
melting
A solid absorbing heat to turn into a liquid
mixture
A substance made up of more than one element or compound not chemically bonded together so that they retain their individual properties
sublimation
A solid that absorbs enough heat to instantly turn into a gas
the molar ratio
The proportion of moles between reactants and products in a chemical reaction
vaporization
A liquid absorbing heat to turn into a gas. Vaporization can occur randomly from a liquid's surface. Synonym for boiling and evaporation.
