Question

A uniform thermometer scale is at a steady state with 0 cm mark at 20 C and 100 cm mark at 100 C . The temperature of 60 cm mark is .....

Answer 1

$\rule{200}{2}$

$\huge\boxed{\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}}$

As 60cm is at distance of 60 from the 0 cm mark and 40 from the 100cm mark; by applying the formula of conduction

(T - 20)/60 = (100 - T)/40

4T - 80 = 600 - 6T

T = 68 C
