A. We have to give energy to benzene to evaporate it. Statement true.
B. If heat is absorbed then the enthalpy must be positive.

Answer:
Shear stress
Explanation:
Shear stress occurs in what we call transform boundaries. Transform boundaries happen when two tectonic plates slide against each other.
There are 3 main types of stress and shear stress is one of them.
Additional information ahead, continue reading if you'd like to know more.
Compression stress occurs when two tectonic plates are convergin g (at convergent boundaries).
Tension stress occurs when two tectonic plates are diverging, or when they are moving apart, (at divergent boundaries).
