The testing of tactile (touch) and other forms of sensibility: Dr. Jones, the neurologist, ran a series of esthesioscopies to try to determine the cause of the difficulty Iva was experiencing while tasting and smelling foods.

Pertaining to low temperatures or cold habitats: Mr. Smith told his students to make a list of psychric areas in the world where ice and snow existed throughout the year.

A painful sensation of cold: Psychroalgia can be a morbid state characterized by an agonizing and subjective feeling of being cold.

A reference to plants in which self-pollination takes place within flowers that remain closed because of abnormally cold conditions: Some types ov vegetation in cold climates are psychrocleistogamic in that they rely on fertilising themselves for reproduction and not by insects or wind.

1. The perception of feeling cold even though the body is warm: Even though Jim was wearing a heavy winter coat and ear muffs, he was experiencing psychroesthesia and could not get warm.

Bathing in cold water: In some countries, psychrolus takes place on the first of January each year for those who are very courageous to take a quick swim in in the town's lake or river.

A device for measuring app the humidity of the atmosphere by the difference in temperature between two thermometers: A psychrometer keeps the bulb of one thermometer to stay moist, the other one dry. Evaporation from the moist bulb lowers the reading of that thermometer and the greater the difference in readings, the drier the air. No difference indicates 100% relative humidity.

The study of the physical laws that influence air and water mixture: In the science of psychrometry, the calculation of relative humidity and water vapor pressures from wet and dry bulb temperatures and barometric pressure; whereas relative humidity is the value ordinarily employed, the vapor pressure is the measurement of physiological significance.

An organism that grows best at a low temperature: A psychrophil is a form of life that thrives best from 0° to 32° C (32° to 86° F) with optimum growth occurring at 15° to 20° C (59° to 68° F). °

In biology, pertaining to an organism thriving at low temperatures: Psychrophilic bacteria are extremophilic and are capable of growth at very low temperatures of 0° C to 15° C, or even best at 15° C to 20° C.

1. An abnormal dread of cold conditions, such as cold weather: Helen really hated to go to school during winter because of her psychrophobia.

People who have psychrophobia tend to keep their houses very warm, overdress, and avoid eating or drinking things that are cold or have crushed ice or ice cubes.
