States of matter and reactions
firm and stable in shape; not liquid or fluid.
Solids
Freezing Point
Products are the end-result of the reaction and are written on the right-hand side of the equation. True or false
true
the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.
Temperature
a substance that has no fixed size or shape
Gas
The temperature at which a material changes from a gas to a liquid
Condensation point
Reactants are starting materials and are written on the left-hand side of the equation. True or false
true
energy that is transferred from one body to another as the result of a difference in temperature.
Heat
substance composed of the chemical elements hydrogen and oxygen
Liquid
the point at which materials changes from a solid to a liquid
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
covection
Phase Change
a chemical reaction that releases energy by light or heat.
Exothermic reaction
the energy contained within a system that is responsible for its temperature
Thermal Energy
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
conduction
made by chemically changing the starting substances to create a material with different characteristics
synthetic material
any chemical reaction that absorbs heat from its environment.
endothermic reaction
the temperature at which a liquid's saturated vapour pressure equals the atmospheric pressure surrounding it.
Boiling Point
energy that comes from a source and travels through space at the speed of light.
Radiation
