Thermodynamic system is said to be in thermal contact with another system when it can exchange energy through heat. The thermal isolation is an idealisation as real systems are always in thermal contact with their environment to some related extent. When two solid bodies are in contact, a resistance to heat transfer exists between the bodies. The study of heat conduction between such bodies is called thermal contact conductance.

1. Valency is the maximum no. of electrons which an atom can lose or gain while oxidation no. is the actual no. of electrons which the element lose or gain to form a molecule.
2. Valency is the property of an isolated atom while oxidation state is calculated for an atom is present in a molecule i.e, in a bonded state.
3. Valency of an element remains the same while its oxidation state may be different in different molecules.

Mr. Braun, the history teacher was an orthodox and ordinary teacher. He expected his students to be passive listeners only. When Einstein expressed his thoughts and ideology while answering a question, Mr. Braun was annoyed at him. Instead of appreciating his uniqueness and curiosity to know the causes behind the Prussian war, he made fun of his sensible and scientific ideas.

Bond energy (E) or bond enthalpy (H) is the measure of bond strength in a chemical bond. Thus, it's not about the combing of the bonds.

The molecular mass of a substance is the number of times the molecule of the substance is heavier than one-twelth the mass of an atom of carbon -12. Or, the molecular mass is equal to the sum of its atomic masses of all the atoms present in one molecule of a substance. For eg: Water (H2O)

Atomic mass of H= 1 unit
Atomic mass of O =16 units
The molecular mass of water = 2 × atomic mass of H+1 × atomic mass of O
= 2 × 1 + 16 × 1
= 18 units
