A thermometer scale is calibrated (marked off) in a degree Celsius from 1 oC to 50 oC. Determine
how many significant figures should be used to express the outdoor temperature if the temperature is
more than 1 oC and less than 10 oC:

(A) 1 (B) 2 (C) 3 (D) 4

• chemistry -

You can read it to 1 degree and estimate the second place. So 2 is the correct answer.
