Lab Manual 12 Temperature There are two temperature scales: the Fahrenbeit (F) and Celsius (centigrade, C) scales (Fig. 2.5). Scientists ase the Celsius scale. 230 1. Stady the two scales in Figure 2.5, and complete the following information Experimental Procedure: Temperature 220 s30-100 Boiling 200 F - a Water freezes at 190 C.

Answer 1

1a. Water freezes at 32^o F = 0^o C

1b. Water boils at 212^o F = 100^{​​​​o} C

2. Human body temperature 98^oF

So human body temperature in Celsius scale =

^O​​​​​​C = (^o​​​​​​F - 32^o)/1.8 = (98-32)/1.8 = 66/1.8 = 36.67^o​C

Therefore human body temperature in Celsius scale is 36.67^oC

3. Room temperature = 22^o C

Surface of your skin = 24^oC

Cold tap water in a 50ml beaker = 21^oC

Hot tap water in a 50ml beaker = 25^oC

Ice water = 5^oC
