Who named the Celsius?
The 9th CGPM and the CIPM (Comité international des poids et mesures) formally adopted "degree Celsius" (symbol: °C) in 1948.
What are the cooling methods used for cooling an alternator?
Air cooling ,hydrogen gas cooling ,water cooling
Is a btu the same for cooling or heating?
Yes, a BTU (British Thermal Unit) is the same for both heating and cooling. It is a unit of energy used to quantify the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit, regardless of whether the energy is being used for heating or cooling purposes. However, the context of its application differs, as BTUs are typically associated with heating systems in winter and cooling systems in summer.
On this temperature scale water boils at 100 degrees?
There are three main temperature scales in use: degrees Celsius, degrees Fahrenheit, and Kelvin. Of these three, the boiling point of water at STP is 100 degrees Celsius.
What is the specific gravity of ethanol?
The specific gravity of ethanol is 0.794. This is for pure 100% ethanol. Specific gravity is the ratio of the density of a substance compared to the density of water. For example, water weighs 8.33 lb/gal at standard conditions (60 deg F). Ethanol weighs 6.61 lb/gal at standard conditions (60 deg F). Therefore, the specific gravity of ethanol is 6.61 divided by 8.33, equals 0.794. A person can verify this result (0.794) by very fundamental experimental testing. Get a gallon of pure water and weigh it precisely. THIS will yield the number 8.33 lbs. Then do the same for ethanol; weigh a gallon of pure ethanol. This will yield the number 6.61 lbs. VOILA! 6.61 divided by 8.33 equals 0.794. I did NOT actually do this weighing of the two liquids, but I COULD! I instead looked the values up in a standard reference book. My copy of "The Data Book on Hydrocarbons", also commonly referred to as 'the Maxwell data book', is a very familiar book to any one who works around the oil industry, as I did for 38 years.
What degree Celsius does water reach maximum density?
Water reaches maximum density at 4 degrees Celsius
Why cooling effect of ice at 0 degree Celsius is more than same amount of water at 0 degree Celsius?
Water at 0 oC is ice.
What is density of water at 36 degree celsius?
The density of water at 36 0C is 0,99367 g/cm3.
Water is most dense at what degree celsius?
Water has the greatest density at 4ºC or 39.2ºF
What is the density of water if the temperature is 20 degree Celsius?
The density of water at 20 degrees Celsius is approximately 998 kg/m³.
What is the density of water at 39.6 degree Celsius?
0.9923710 g/mL @39.6C
What is the density of water at 27 degree celsius?
The water density at 27 0C is 0,9965162 g/cm3.
What is density of water at 24 degree Celsius?
The density of water at 24 degrees Celsius is approximately 997 kg/m^3.
What is the density of di water at 22.9 degree Celsius?
it is 0.997561, internationally excepted value
What is density of water at 37 degree celsius?
The density of water at 37 degrees Celsius is 0.9922 grams per cubic centimeter.
What is the density of water at 27 degree Celsius and 30degree Celsius?
At 27 degrees Celsius, the density of water is around 997.77 kg/m^3, while at 30 degrees Celsius, the density decreases to approximately 995.65 kg/m^3. This decrease in density as temperature increases is due to the expansion of water molecules at higher temperatures.
What is the state of water at 100 degree Celsius 0 degree Celsius 4 degree Celsius?
At 100 degrees Celsius, water is in a gaseous state as steam, assuming standard atmospheric pressure. At 0 degrees Celsius, water is in a solid state as ice. At 4 degrees Celsius, water is in a liquid state and exhibits its maximum density, which is crucial for aquatic life. These states reflect the unique properties of water and its behavior across different temperatures.
