A temperature scale has an upper fixed point of 260mm and the lower fixed point of 50mm. what will be the reading on this scale when the thermometer read 125°F​

the reading on the scale is 158.5 mm.

Explanation:

Given;

upper fixed point of the temperature scale, x₁ = 260 mm

lower  fixed point of the temperature scale, x₂ = 50 mm

upper temperature scale, T₁ = 212 °F

lower temperature scale, T₂ = 32 °F

thermometer reading, t = 125 °F, let the reading on the scale = x

Interpolate as follows to determine the value of "x"

Therefore, the reading on the scale is 158.5 mm.
