In 1738 Josias Weitbrecht (1702–1747) recalibrated the Delisle thermometer with 0 degrees as the boiling point and 150 degrees as the freezing point of water. The Delisle thermometer remained in use for almost 100 years in Russia. Thus, the unit of this scale, the Delisle degree (sometimes...

Celsius, as well asFahrenheit, are both thetemperature scales. Celsius is the temperature scale for themetric systemand Fahrenheit for theimperial system. The points on the above table refer to pure water points at atmospheric pressure at sea level. From the above numbers, one may easily deduct...

However, Kelvin uses a different starting point for its scale than Celsius. Absolute zero, the coldest possible temperature, is at 0 Kelvin, which is -273.15° in the Celsius scale. This makes the Kelvin scale a useful tool for scientists who want to measure temperatures by their distance ...
a) transesterifying material containing PET by reacting with ethanediol, typically under pressure and with a mixture of PET oligomers having chain lengths of about 200 units and are in the form of solid flake at a temperature at or near the boiling point of ethanediol at the reactor pressure...
The boiling point of liquid nitrogen (at 1 atm of pressure) is 77.34 Kelvin. What is this temperature on the Celsius scale? Which is larger 1 degree Celsius or 1 degree Fahrenheit? Explain why. At what temperature on the Fahrenheit scale will the reading be double of the reading on the ...
But, before you all begin your next set of experiments using microwave ovens, you also need to understand, that using microwave to heat liquids can be quite different from heating liquids in a metal pot on the stove. In a metal pot on the stove, when the liquid reaches its boiling point...
