Researchers find flexible solution for separating gases

For a broad range of industries, separating gases is an important part of both process and product—from separating nitrogen and oxygen from air for medical purposes to separating carbon dioxide from other gases in the process ...

Cooler states now forced to grapple with extreme heat

As temperatures soared into the 90s, the heat and humidity hit the concrete in Astoria, Queens, and bounced into the air. People moved along the scorched sidewalk slowly, their clothes drenched with sweat.

New biocatalytic method eliminates cyanide in nitrile production

If the household cleaner emits a lemon-like odor, this may be due to a nitrile called citronellyl nitrile. These versatile chemical nitrile groups are also used in the manufacture of active pharmaceutical ingredients, superglue ...

Room temperature

Room temperature is a common term to denote a certain temperature within enclosed space at which humans are accustomed. Room temperature is thus often indicated by general human comfort, with the common range of 7°C (44°F) to 32°C (90 °F),[citation needed] though climate may acclimatize people to higher or lower temperatures.

The term can also refer to a temperature of food to be consumed, which is placed in such a room for a given time. Furthermore, it may refer to a certain temperature within settings of scientific experiments and calculations.

For human comfort, desirable room temperature greatly depends on individual needs and various other factors. According to the West Midlands Public Health Observatory, 21 °C (73 °F) is the recommended living room temperature, whereas 18 °C (64.4 °F) is the recommended bedroom temperature. A study carried out at the Uppsala University, on indoor air quality and subjective indoor air quality (SIAQ) in primary schools, states that perception of high room temperature was related to a poor climate of cooperation. To achieve a good SIAQ, it recommends room temperature should be at a maximum of 31.0 °C (92.6 °F).
