barothermograph
(s) (noun), barothermographs
(pl)
An instrument or tool for recording simultaneously the pressure and the temperature of the atmosphere.
barothermohygrogram
A graphic representation of pressure, temperature, and humidity readings, as made by a barothermohygrograph.
barothermohygrograph
(s) (noun), barothermohygrographs
(pl)
An automatic instrument that simultaneously records the temperature, pressure, and humidity of the atmosphere.
bathythermogram
(s) (noun), bathythermograms
(pl)
The record that is made by a bathythermograph (an instrument that records water temperature in relation to ocean depth): As part of the course on oceanography, Mandy had to explain what a bathythermogram was and what was indicated by the documentation it presented.
bathythermograph
(s) (noun), bathythermographs
(pl)
An instrument that automatically records the temperature of water at various depths.
bathythermographic
(adjective), more bathythermographic, most bathythermographic
A reference to an instrument which automatically records the temperatures of water at various depths.
bathythermosphere
(s) (noun), bathythermospheres
(pl)
A device or instrument for recording the temperature against the depth (pressure) in the ocean from a ship that is underway or in motion: A bathythermosphere, or BT, was used by senior students for scientific purposes for the university, and especially to find out the distribution of water temperature in relation to th deepness of the ocean.
bios
1. Organic life.
2. A group of substances (including inositol, biotin, and thiamine) necessary for the most favorable growth of some yeasts.
biothermal
Pertaining to the inter-relationship of temperature and living organisms.
British thermal unit (Btu)
1. The quantity of heat required to raise the temperature of one pound of water from 60 degress to 61 degrees Fahrenheit (3.9 C to 4.4C) at a constant pressure of one atmosphere.
2. The quantity of heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees to 212 degrees Fahrenheit at a constant pressure of one atmosphere, equal to approximately 1055.056 joules.
A joule is the International System unit of energy or work, equal to the work done when the application point of one newton force moves one meter in the direction of application. Symbol J [Named for the British physicist James Prescott Joule, 1818-1889, noted for his research on the mechanical equivalent of heat].
catathermal
Falling temperature or lowering of heat.
catathermometer, katathermometer
1. An alcohol thermometer, with a dry bulb and a wet bulb, which measures how quickly air is cooling; and so, permitting an estimate of evaporation of moisture from the body.
2. A device consisting of two thermometers, one a dry bulb and the other a wet bulb.
Both are heated to 110°F (43.3°C) and the time required for each thermometer to fall from 100° to 90°F (37.8° to 32.2°C) is noted. The dry bulb gives the cooling power by radiation and convection, the wet bulb by radiation, convection, and evaporation.
From this, the temperature as it affects the body can be deduced; or it is a measure of the heat content of the environment that takes into account air movement as well as temperature.
chronoisothermal
(adjective), more chronoisothermal, most chronoisothermal
Relating to a diagram exhibiting the course of the mean monthly temperature of a place for each hour of the day: A chronoisothermal chart indicates the relationship between time and temperature.
Relating to time and temperature: The chronothermal factor is related to the superposition principle.
