The amount of heat absorbed in a chemical reaction is measured with a thermometer.
The joule is the SI unit of heat.
One calorie equals 4.184 joules.
Entropy is the heat content of a system under pressure.
A reaction that has a negative change in enthalpy is exothermic.
Heat of combustion is the heat released by the complete combustion of one mole of a substance.
Catalysts are not consumed during a reaction.
In nature, processes tend to occur that lead to a higher energy state.
Concentration does not have an effect on a reaction.
Spontaneous chemical reactions will have a negative change in Gibbs energy.
Natural processes tend to gain disorder.
Enthalpy describes the disorder in a system.
Gibbs energy is the energy in a system available for work also known as free energy.
Nucleons are protons and neutrons.
The force between protons in a nucleus is a weak force.
The sum of the masses of individual nuclear particles is less than their masses when combined.
Nuclear binding energy is released when a nucleus is formed.
Nuclei with an even number of protons and neutrons tend to be unstable or radioactive.
Radioactive decay refers to the emissions of particles or gamma radiation from a nucleus.
Fusion is the process in which a radioactive nucleus splits to form less massive nuclei.
Becquerel discovered the process of radioactivity.
Half-life is the time it takes half of a given number of atoms in a radioactive sample to decay.
Beta particles are the same as helium nuclei.
Gamma rays and visible light are two types of electromagnetic radiation.
Transmutation is the change in a nucleus due to the change in the number of protons.
In a nuclear equation, only nuclei are represented.
Carbon-14 is used to find the age of ancient objects.
Any radioactive isotope can fission.
A nuclear reactor produces energy from uncontrolled fission.
A characteristic of a chain reaction is that the material that begins the reaction is also one of the products.
Nuclear fusion takes place on the sun.
