Correct option is (2) 32°F
We know melting point of ice in Celsius scale, C = 0∘C
Let F be the temperature in Fahrenheit scale
We also know that,
\(C = \frac {5}{9} (F - 32)\)
\(\Rightarrow 0= \frac {5}{9} (F - 32)\)
\(\Rightarrow F = 32 ^\circ F\)
\(\therefore\) Melting point of ice in Fahrenheit scale is 32∘F.
