Temperature vs. Humidity — What's the Difference?

Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter.

Humidity is the concentration of water vapour present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye.

The degree of hotness or coldness of a body or environment.

Dampness, especially of the air.

A measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale.

Relative humidity.

The degree of heat in the body of a living organism, usually about 37.0°C (98.6°F) in humans.

Dampness, especially that of the air.

An abnormally high condition of body heat caused by illness; a fever.

The amount of water vapour in the air.

A measure of cold or heat, often measurable with a thermometer.

Moisture; dampness; a moderate degree of wetness, which is perceptible to the eye or touch; - used especially of the atmosphere, or of anything which has absorbed moisture from the atmosphere, as clothing.

An elevated body temperature, as present in fever and many illnesses.

The content of water vapor in the air, expressed as a percent of the maximum amount of water vapor that the air can hold at the given temperature; also called relative humidity. The capacity of the air to hold moisture increases with temperature, so if the temperature changes without changing the absolute content of the atmospheric moisture, the relative humidity will also change.

(thermodynamics) A property of macroscopic amounts of matter that serves to gauge the average intensity of the random actual motions of the individually mobile particulate constituents. [http://arxiv.org/pdf/physics/0004055]

Wetness in the atmosphere

(obsolete) The state or condition of being tempered or moderated.

The balance of humours in the body, or one's character or outlook as considered determined from this; temperament.

Constitution; state; degree of any quality.

Freedom from passion; moderation.

Condition with respect to heat or cold, especially as indicated by the sensation produced, or by the thermometer or pyrometer; degree of heat or cold; as, the temperature of the air; high temperature; low temperature; temperature of freezing or of boiling.

Mixture; compound.

The degree of heat of the body of a living being, esp. of the human body; also (Colloq.), loosely, the excess of this over the normal (of the human body 98°-99.5° F., in the mouth of an adult about 98.4°).

The degree of hotness or coldness of a body or environment (corresponding to its molecular activity)

The somatic sensation of cold or heat
