Question

A mercury-in-glass thermometer reads-20° at the ice point and 100°at the steam point. Calculate the Celsius temperature corresponding to 70° on the thermometer

Answer 1

Dear Student,

● Answer -

Thermometer reading = 76°

● Explanation -

Given thermometer reads 20° for ice point. i.e. 0 ℃ and 100° at steam point. i.e. 100 ℃.

This means 1 ℃ reads (100-20)/(100-0) = 80/100 = 0.8° in modified thermometer.

So temperature corresponding to 70 ℃ will read 20 + 70×0.8 = 76° on the modified thermometer.

Thanks dear. Hope this helps you...
