Question

which of the following is not endothermic
A.fusion
B.vaporization
C.temperature
D.insoluble heavy impurities

Answer 1

The last 2 options do not make sense. Endothermic is a process where heat is absorbed. So in fusion and vaporisation, heat is absorbed. So it cannot be the options. Please check option 3/4 again as endothermic is a process not a physical quantity like temperature.
