Room temperature in celsius in chemistry
WebSimply, temperature is a measure of the relative “hotness” or “coldness” of any object or system. Solved Example. Question: Ethyl alcohol boils at 78.5 o C and freezes at -117 o C under a pressure of 1 atm. Convert these temperatures to Kelvin scale. Solution: We have Kelvin = temperature = Celsius temperature + 273.15 = 78.5 + 273.15 ... WebWhat is normal room temperature?
