I got this question in an international level competition.

My question is from Energy Types topic in chapter Liquids and Gases in Equilibrium with Solids and Energy: Terminology, Concepts, and Units of Basic Chemical Engineering

Answer 1

Right answer is (c) 5^oC

The explanation: 2 = (37 – T)/(T + 11), => T = 5^oC.
