work
In physics, a force is said to do work if, when acting there is a displacement of the point of application in the direction of the force
Got it
chemical energy
In chemistry, chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances
Got it

Thermal energy
In thermodynamics, thermal energy refers to the internal energy present in a system due to its temperature
Got it
heat
In physics, heat is energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter
Got it
Energy
In physics, energy is a property of objects which can be transferred to other objects or converted into different forms

Melting
Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid
Got it
potential energy
In physics, potential energy is energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors

heat transfer
Heat transfer is the exchange of thermal energy between physical systems
Thermodynamics
Thermodynamics is a branch of science concerned with heat and temperature and their relation to energy and work
absolute zero
Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0
phase transition
The term phase transition is most commonly used to describe transitions between solid, liquid and gaseous states of matter, and, in rare cases, plasma
geothermal
Geothermal energy is thermal energy generated and stored in the Earth
energy transformation
Energy transformation or energy conversion is the process of changing one form of energy to another form of energy
exothermic reaction
An exothermic reaction is a chemical reaction that releases energy by light or heat
ideal gas law
The ideal gas law is the equation of state of a hypothetical ideal gas
conductors
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions
Convection
Convection is the movement of groups of molecules within fluids such as liquids or gases, and within rheids
Radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium
Celsius scale
Celsius, also known as centigrade, is a scale and unit of measurement for temperature
endothermic reaction
The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings; usually, but not always, in the form of heat
fission
In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts
fusion
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles
