(C*1.8+32=F). This scale is named for G. D. Fahrenheit (1686-1736), the German physicist, who invented it and was the individual who introduced the use ofmercury (Hg)instead of alcohol in thermometers. Because of the health dangers related with mercury, the use of mercury in ...
freez·ing point (frē′zĭng) The temperature at which a liquid becomes a solid. For a given substance, the freezing point of its liquid form is the same as the melting point of its solid form. The freezing point of water is 32°F (0°C); that of liquid nitrogen is -345.75°F ...
Do the Celsius and Fahrenheit temperature scales ever read the same?Determine the temperature at which the diffusivity, D, of Cu in Al is twice the diffusivity at 500 KConsider alcohol and a mercury thermometer that read exactly 0 ? C at the ice point and 100 ? C at the st...
Freezing or solidification is when a liquid turns to a solid. Melting is the opposite: solid substances turn to liquid. The point(s) at which freezing and melting happen are called the freezing and melting points, respectively.Answer and Explanation: In most substances, the freezing po...
Answer in Kelvin. What are the temperatures for freezing water on the Celsius and Fahrenheit scales? What are the temperatures for boiling water on the Celsius and Fahrenheit scales? How do you calculate the difference in temperature b/t the freezing point of water and the normal boil...
in a warm place, but if we want them to melt quickly, then we can put them in an oven. The melting process is the same for all substances, but their melting point can differ. For example, mercury melts at a temperature of -37.89 degrees Fahrenheit or -38.83 degrees Celsius, whereas ...
. The most common kind of thermometer is made with mercury(水银)inside a clear glass tube.As mercury (or any other liquid ) becomes hot,it expands.As it gets colder,it contracts(收缩).That is why on hot days the mercury line is high in the glass tube.(3)...
Parshall became intolerably frigid in February 1936 at -60 degrees Fahrenheit. Interestingly,this recording was made by an unnamed coal-miner, who had volunteered to be a weather observer, with the help of a special (mercury-thallium alloy) thermometer. ...
freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. Whenitwas removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point. ...
freez·ing point (frē′zĭng) n.Abbr.fp 1.The temperature at which a liquid of specified composition solidifies under a fixed pressure, usually standard pressure. 2.The temperature at any fixed pressure at which the liquid and solid phases of a substance of specified composition are in equ...
