Which of the following statements is (are) true ?a)The evaporation of ...
Evaporation of water is an endothermic change
- When water evaporates, it absorbs energy from its surroundings to break the intermolecular forces holding the water molecules together. This absorption of energy makes evaporation an endothermic process.
Conversion of white phosphorus to red phosphorus is an exothermic reaction
- The conversion of white phosphorus to red phosphorus releases energy in the form of heat. This release of energy makes the reaction exothermic.
Heat of neutralisation of a strong acid with a strong base is always the same
- The heat of neutralization is the heat released when an acid reacts with a base to form water and a salt. For a strong acid-strong base reaction, the heat of neutralization is always constant and does not depend on the specific acid or base used.
Therefore, all three statements (A, B, C) are true. It is important to understand the concepts of endothermic and exothermic reactions, as well as the heat of neutralization, to answer questions like these effectively in exams like JEE.
