Temperature, thermal / heat energy
Thermal energy
Thermal expansion
Thermal expansion is the tendency of matter to change in shape,area, and volume in response to temperature alternations.
When a substance is heated, tis particles move more and thus maintain a greater average separation.

Definition
Thermal energy is the internal energy of an object due to the kinetic energy of its atoms and/or molecules.
The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.
-
Sensible heat is the internal potential energy of a system (spin, vibration, rotation...) in the form of thermal energy. The magnitude of sensible heat of an object is related to the mass, the specific heat of the object and the change in temperature.
Latent heat is the amount of thermal energy released or absorbed during a change of phase of the material (from liquid to gas, liquid to solid...). A solid has more latent energy than a gas.
Properties
-
-
When objects with different temperatures are in the same environment, energy is transferred from objects at higher temperatures to objects at lower temperatures until everything is at the same temperature (thermal equilibrium).
Temperature
-
Temperature presents the condition of a body to either transfer or absorb thermal energy from the surrounding environment or another objects.

Heat energy
Heat is thermal energy transferred between two systems at different temperatures that come in contact.
