Temperature vs time plots, showing the Mpemba Effect. The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions.
Hot cognition is a hypothesis on motivated reasoning in which a person's thinking is influenced by their emotional state. Put simply, hot cognition is cognition coloured by emotion. [1] Hot cognition contrasts with cold cognition, which implies cognitive processing of information that is independent of emotional involvement. [2]
Thermoreceptors of the skin sense the temperature of water. A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.
In the scientific community, there was a debate about how objects cooled and in 1461 Marliani confirmed that he had experimentally observed hot water freezing faster than cold water. In his experiment he stated that he had used four ounces of unheated water and four ounces of boiled water, which he placed in similar containers outside on a cold ...
Humans inhabit hot climates, both dry and humid, and have done so for millions of years. Selective use of clothing and technological inventions such as air conditioning allows humans to live in hot climates. One example is the Chaamba, who live in the Sahara Desert. They wear clothing that traps air in between skin and the clothes, preventing ...
Bill Clinton is one proud grandpa!. On Monday, Nov. 25, the former President of the United States, 78, appeared on an episode of Live with Kelly and Mark and spoke about how he and the former ...
A Democratic committee staffer made the case for seniority, arguing that the House GOP system — in which committee chiefs get three-term limits, requiring waivers for fourth terms — is a ...
Well, if you put a cup of cold water and a cup of boiling hot water in the freezer, the hot water would raise the temperature of the whole freezer; thus they would both freeze in the same time, but the cold water will take longer than if it were in the freezer by itself.
