the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations.

the internal energy of an object due to the kinetic energy of its atoms and molecules moving or vibrating

the transfer of thermal energy between substances or systems due to a difference in temperature, flowing spontaneously from hotter regions to cooler ones.

the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.

firm and stable in shape; not liquid or fluid.

a substance that flows freely but is of constant volume, having a consistency like that of water or oil.

a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume

the process of turning from liquid into vapor.

water which collects as droplets on a cold surface when humid air is in contact with it.

accompanied by or requiring the absorption of heat.

accompanied by the release of heat.

Term	Definition
Temperature	the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
Thermometer	an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations.
Thermal energy	the internal energy of an object due to the kinetic energy of its atoms and molecules moving or vibrating
Heat	the transfer of thermal energy between substances or systems due to a difference in temperature, flowing spontaneously from hotter regions to cooler ones.
Conduction	the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Covection	the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Radiation	the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Solid	firm and stable in shape; not liquid or fluid.
Liquid	a substance that flows freely but is of constant volume, having a consistency like that of water or oil.
Gas	a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume
Melting	becoming liquefied by heat.
Freezing	the freezing point of water.
Evaporation	the process of turning from liquid into vapor.
Boiling	at or near boiling point.
Condensation	water which collects as droplets on a cold surface when humid air is in contact with it.
Endothermic	accompanied by or requiring the absorption of heat.
Exothermic	accompanied by the release of heat.
