The distance between the fixed points of a mercury-in-glass thermometer is 30 cm. Determine the temperature when the mercury level is 10.5 cm above the lower fixed point
28.6ºC
30.0 ºC
35.0 ºC
40.5 ºC
Correct answer is C
10.5−030−0 = c−0100−0
10.530 = c100
cross multiply:
10.5 * 100 = 30c
35.0 ºC = c
