Answer : At 120°C
Explanation : At 120°C temperature the boiling point of this substance is observed in the given graph.
As per the definition of the boiling point, <em>"It is the temperature at which the vapour pressure of the given substance becomes equal to the standard surrounding atmospheric pressure"</em>
Here, in this graph, it is clearly seen at 120°C where the substance raises to the high temperature and remains stable for certain period of time and then again slightly increases.

A. synthesis
Explanation:
The reaction given is a synthesis reaction in which two substances combines to give a product.
In this reaction:
4Fe + 3O₂ → 2Fe₂O₃
The reaction involves the formation of a single product from two or more reactants.
The formation of a compound from union of the constituent elements also falls into this category of reaction.
Answer:
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat
