Thermodynamic magic enables cooling without energy consumption

Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears ...

Successful tests of a cooler way to transport electricity

Like a metal python, the huge pipe snaking through a CERN high-tech hall is actually a new electrical transmission line. This superconducting line is the first of its kind and allows vast quantities of electrical current ...

Demonstrating a weak topological insulator in bismuth iodide

Topological insulators are one of the most exciting discoveries of the 21st century. They can be simply described as materials that conduct electricity on their surface or edge, but are insulating in their interior bulk. ...

Green material for refrigeration identified

Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners.

Graphene gives a tremendous boost to future terahertz cameras

In a recent study, researchers developed a novel graphene-enabled photodetector that operates at room temperature, is highly sensitive, fast, has a wide dynamic range, and covers a broad range of THz frequencies. The researchers ...

Team makes artificial atoms that work at room temp

Ultra-secure online communications, completely indecipherable if intercepted, is one step closer with the help of a recently published discovery by University of Oregon physicist Ben Alemán.

Shrinking the carbon footprint of a chemical in everyday objects

The biggest source of global energy consumption is the industrial manufacturing of products such as plastics, iron, and steel. Not only does manufacturing these materials require huge amounts of energy, but many of the reactions ...

The mechanism of high-temperature superconductivity is found

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).
