Vocab
When heat is released when a chemical reaction is occuring.
Exothermic Reaction
A process that leads to the transformation of one set of chemical substances to another.
Chemical Process
The branch of chemistry concerned with the quantities of heat evolved or absorbed during chemical reactions.
Thermochemistry
Type of chemical reaction that involved buring of a substance in the presence of oxygen releasing energy in the form of heat and light
Combustion
The transfer of thermal energy from a hotter object to a cooler one.
Heat transfer
The heat energy contained in a product. Usually responsible for the temperature.
Thermal (heat) energy
The method of changing one or more chemical compounds.
Chemical Reaction
Endothermic Reaction
This type of chemical reaction involved a single compound breaking down into 2 or mroe simpler substances
Decomposition
This type of energy transfer occurs through direct contact of molecules, allowing heat to pass from one substance to another
Convection
Energy that is transferred by electromagnetic radiation.
Radiant (heat) Energy
Reactants
A chemical reaction during which plants convert radiant energy from the sun to chemical energy.
Photosynthesis
Process that breaks down food in your stomach
Digestion
This form of energy transfer doesn't require a medium and can occur through a vacuum like the heat from the sun
Raditation
What a chemical equation starts with.
Reactants
When a reaction _______ heat, the product of the reaction becomes colder.
Absorbs
The measure of the average kinetic energy in a substance
Temperature
This reaction/ process is involved with iron and oxygen and water
Rust
The temperature scale is based on the freezing and boiling points of water at 0 and 100 degrees.
Celsius
What a chemical equation ends with.
Products
When a reaction ________ heat the product of the reaction becomes hotter.
Exothermic
This principle states that energy cannot be created or destroyed only transferred or transformed
Law of conservation of energy
Metabloic process converting sugars into acids, gases, or alcohol, in the absence of oxygen.
Fermentation
This temperature scale starts at 0 where there is no molecule motion
Fahrenheit
