WebThe relation between humidity and temperature is inversely proportional. If temperature increases, it will reduce relative humidity; thus, the air will become drier. When the … WebThe temperature-humidity index I (or humidex, for short) is the perceived air temperature when the actual temperature is T and the relative humidity is h, so we can write I = f ( T, h ). The following table of values of I is an excerpt from a table compiled by the National Oceanic & Atmospheric Administration. (a) What is the value of f (85, 70)? Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest.
