"The term 'thermal energy' is used loosely in various contexts in physics and engineering..."
The energy associated with the temperature of an object or substance.
Thermodynamics: This is the branch of physics that deals with the interactions of systems involving temperature, pressure, and volume.
Heat transfer: This refers to the movement of thermal energy between materials due to a difference in temperature.
Kinetic theory of matter: This theory explains the behavior of matter in terms of the motion and interaction of its particles.
Specific heat capacity: This is the amount of thermal energy required to raise the temperature of a substance by one degree Celsius.
Phase changes: This refers to the transition of matter from one state (solid, liquid, gas) to another due to changes in temperature and/or pressure.
Conduction: This is the transfer of thermal energy through a substance due to a temperature gradient.
Convection: This is the transfer of thermal energy through the movement of a fluid (usually a gas or liquid) due to differences in temperature and density.
Radiation: This is the transfer of thermal energy through electromagnetic waves (e.g. infrared radiation).
Thermal equilibrium: This is the state where two objects in contact have the same temperature and there is no net transfer of thermal energy between them.
Laws of thermodynamics: These are a set of principles that govern the behavior of thermodynamic systems, including energy conservation, entropy, and the impossibility of perpetual motion.
Heat: It is the transfer of thermal energy from one object to another object at a lower temperature.
Conduction: It is the transfer of thermal energy through a material by molecular collisions.
Convection: It is the transfer of thermal energy from one place to another by the motion of the fluid or gas.
Radiation: It is the transfer of thermal energy by electromagnetic waves.
Kinetic Energy: The movement of particles that create heat and temperature.
Potential Energy: The energy stored by an object based on its position, stored or compressed.
Sensible Heat: The amount of heat required to change the temperature of a substance or object.
Latent Heat: The amount of heat required to change the state of a substance.
Activation Energy: The minimum amount of energy required for a chemical reaction to occur.
Specific Heat: The amount of energy required to raise the temperature of a unit mass of a substance by one degree Celsius or one Kelvin.
