Which one of the following is the correct relation between Celsius and Fahrenheit temperature scales? (Symbols carry their usual meanings)
General KnowledgePhysics
- ATF = 10/3Tc + 32
- BTF = 5/9Tc + 36
- CTF = 5/9TC + 36
- DTF = 9/5Tc = 32
Explanation
The Celsius-Fahrenheit relation is TF = (9/5)TC + 32: water freezes at 0 C = 32 F and boils at 100 C = 212 F, fixing the 9/5 slope and the +32 offset. Option D gives this formula (the '=' printed before 32 is a typographical slip for '+').
