ETYM Cf. French perspiration.
Excretion of water and dissolved substances from the sweat glands of the skin of mammals. Perspiration has two main functions: body cooling by the evaporation of water from the skin surface, and excretion of waste products such as salts.
Salty fluid secreted by sweat glands; SYN. sweat, diaphoresis, sudor, hidrosis, water.
steam / stiːm /
ETYM Old Eng. stem, steem, vapor, flame, AS. steám vapor, smoke, odor; akin to Dutch stoom steam, perhaps originally, a pillar, or something rising like a pillar.
Water at boiling temperature diffused in the atmosphere.
In chemistry, a dry, invisible gas formed by vaporizing water.
The visible cloud that normally forms in the air when water is vaporized is due to minute suspended water particles. Steam is widely used in chemical and other industrial processes and for the generation of power.
ETYM Old Eng. vapour, Old Fren. vapour, vapor, vapeur, French vapeur, Latin vapor. Related to Vapid.
Fine separated particles floating in the air and clouding it. A substance in the gaseous state.
(Alternate spelling: vapour).
A visible suspension in the air of particles of some substance; SYN. vapour.
One of the three states of matter (see also solid and liquid). The molecules in a vapor move randomly and are far apart, the distance between them, and therefore the volume of the vapor, being limited only by the walls of any vessel in which they might be contained. A vapor differs from a gas only in that a vapor can be liquefied by increased pressure, whereas a gas cannot unless its temperature is lowered below its critical temperature; it then becomes a vapor and may be liquefied.
ETYM Cf. French vaporisation.
(Alternate spelling: vaporisation).
1. Annihilation by vaporizing something; SYN. vaporisation.
2. The process of becoming a vapor; SYN. vaporisation, vapor, vapour, evaporation.
