Question

Define endothermic reaction and galvanisation.

Answer 1

Answer:

An endothermic reaction takes in energy from the surroundings; like a snowman melting. Exothermic reactions transfer energy to the surroundings, and this energy is usually heat energy, they cause the surroundings to heat up.

Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.

Answer 2

Explanation:

Endothermic Reaction: The reactions in which heat is absorbed by the reactants to form a product are termed as endothermic reactions.

For example, The process of photosynthesis is an endothermic reaction.In this reaction, sunlight is required as energy.

6CO2 + 6H2O + Light energy → C6H12O6 + 6O2

Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.
