Please show me how to do it. Thank you very much!

Temperature Scales Both the Fahrenheit and Celsius temperature scales are based on the freezing point and boiling point of water. The Fahrenheit scale has 180 divisions (degrees) between the freezing point and boiling point with a number assignment of 32 degree F at the freezing point. The Celsius scale has 100 divisions (degrees) between the freezing point and boiling point with a number assignment of 0 degree C at the freezing point. Consider a change of 20 Celsius degrees for a substance. What is the corresponding temperature change in Fahrenheit degrees for that substance? a day when the air temperature is 77 degree F. What is the corresponding Celsius temperature? The Kelvin temperature scale used by scientists is not based on water, but rather on the amount of average available kinetic energy per molecule in a substance. The size of a Kelvin is the same as Celsius degree. (That is, there are 100 divisions between the freezing point and boiling point of water on the Kelvin scale as well.) However, a temperature of 0 Kelvin corresponds to the lowest possible temperature any substance can have since there is no more available kinetic energy that the substance can give up. On the Celsius scale this occurs at -273 degree C. Once again, consider a change of 20 Celsius degrees for a substance. What is the corresponding temperature change for that substance in Kelvins? What are the temperatures of the freezing point and boiling point of water on the Kelvin scale? TK, fp =

Explanation / Answer

now the conversion of kelvin and celcius

they both are of same division

kelvin have a gain of 273

as -273 celcius corresponds to 0 kelvin

kelvin = celcius + 273

k = c +273

3) c = 20

k = 20+273 = 293

4 ) water freezes at 0 degree celsius

=> c = 0

k = 0+273 = 273

5) water boils at 100 degree celcius

=> c = 100

k = 100 +273 = 373
