- Sensation of heat.
- Temperature, or degree of hotness.
- Quantity of thermal energy.
- Radiant heat, or energy of radiation.
2. A tool for measuring temperature; that is, an instrument with a graduated glass tube and a bulb containing mercury or alcohol that rises in the tube when the temperature increases or goes down in the tube when the temperature decreases; in other words, the liquid rises or falls as it expands or contracts according to changes in the temperature.
2. Involving or determined by temperature or temperature measurements.
2. In plant organs, the assumption of, or tendency to assume, certain positions because of one-sided pressure or growth due to heat.
3. A nastic movement caused by a change in temperature.
One example includes the opening and closing of crocus flowers after an increase or decrease in temperature.
2. Pyrexia of vasomotor origin.
2. The environment which enables a neonate (newly born child) to maintain a body temperature of 97.7° F (36.5° C) with a minimal requirement of oxygen and energy.
2. Referring to any process in which a very high temperature is used to bring about the fusion of light nuclei, with the accompanying liberation of energy.
This process is the source of energy of the sun and it is used in the explosion of thermonuclear weapons.
