What are the upper and lower reference temperatures in Celsius and Fahrenheit sc

Question

What are the upper and lower reference temperatures in Celsius and Fahrenheit scales? How are they related? Is there any temperature that reads exactly same in both Celsius Fahrenheit scales? What are the different processes of heat transfer through different materials? How is the temperature of an object connected to heat? Mention at least two ways heat and temperature may be correlated. What is the SI unit of temperature? How is that related to the Celsius scale? What is the unit of heat in metric system? How much amount of heat does it correspond to?

Explanation / Answer

1. for celcius, upper = 100 degree celcius, lower = 0 degree celcius

for fehrenheit , upper = 212 degree fehrenheit, lower = 32 degree fehrenheit

related   C = 5/9 (F-32)

where C and F are temperatures in Celsius and Fahrenheit.

yes both have same value at - 40 degree

2. a) conduction b) cenvection c) radiation

3. q=m×C×T

where m is mass of object

C = specific heat

T = temperaure change

a) when a body absorbs heat, its temperature increases
b) when a body loses heat, its temperature decreases

4. si unit of temperature is kelvin(K)

C + 273.15 = K
