The lower limit of the thermometer scale is -20C, and the upper limit is + 50C. There are 141 divisions in total on the thermometer scale. Find the thermometer division value.
It is known that the lower limit of the thermometer scale is – 20 ° С, and the upper limit is + 50 ° С, that is, the range of measured temperatures is + 50 – (- 20) = 70 (° С). The thermometer has a total of 141 divisions. One of them belongs to the boundary temperature value equal to 0 ° С. Then at 70 ° C there are: (141 – 1) = 140 divisions. To find the division value of the thermometer, it is necessary to divide the range of measured temperatures by the number of scale divisions falling on it: 70: 140 = 0.5 (° С). Answer: the price of a thermometer is 0.5 ° C.
