Question

N mercury thermometer the lower fixed point is 10 degree and upper fixed point is marked at 130 degree at 40 degree celsius temperature thermometer reads 14.5 multiply by a. the value of a is ?

Answer 1

Answer:

In this type of question we use the simple mathematics

Explanation:

As given in question

thermometer reads 40 degree at 14.5 then equation is form

(40-10) = 14.4 x a        we subtracted the 40 degree with 10 because

a = 2+1/12=2.0833     at the point 0 the temperature will be measured 10                                 degree

so the value of a = $2\frac{1}{12}$=2.0833
