The glowing charcoal on the left represents high kinetic energy, while the snow and ice on the right are of much lower kinetic energy. The first thermometers were glass and contained alcohol, which expanded and contracted as the temperature changed.
The Fahrenheit scale was first developed in and tinkered with for some time after that. The main problem with this scale is the arbitrary definitions of temperature. The Fahrenheit scale is typically not used for scientific purposes. The Celsius scale of the metric system is named after Swedish astronomer Anders Celsius — The distance between those two points is divided into equal intervals, each of which is one degree.
The Kelvin temperature scale is named after Scottish physicist and mathematician Lord Kelvin It is based on molecular motion, with the temperature of 0 K, also known as absolute zero, being the point where all molecular motion ceases. The freezing point of water on the Kelvin scale is As can be seen by the kelvin difference between the two, a change of one degree on the Celsius scale is equivalent to the change of one kelvin on the Kelvin scale.
Converting from the Kelvin scale to the Celsius scale or vice versa is easy, as you simply add or subtract Converting between the Celsius and Fahrenheit temperature scales is a little bit trickier but still not too difficult. To convert from Celsius to Fahrenheit, first subtract 32 from the temperature in Fahrenheit then divide by 1. Use the link below to answer the following questions:. Skip to main content. Search for:.

Answer from: campbell The normal freezing point of water is 0 degree Celsius and the normal boiling point of water is degree Celsius. To convert these temperatures to Kelvin, you will add to them. Thus, the freezing point of water at Kelvin temperature is K and the boiling point of water in Kelving is K.
