MP Board · Class 11 · Physics · Thermal Properties of MatterAt what temperature do the Celsius and Fahrenheit scales read the exact same numerical value?
Step-by-Step Solution
Using the relation $\frac{C}{5} = \frac{F - 32}{9}$, let $C = F = x$. Then $\frac{x}{5} = \frac{x - 32}{9} \implies 9x = 5x - 160 \implies 4x = -160 \implies x = -40^\circ$. Hence, option A is correct.
