GENERAL KNOWLEDGE

Detailed explanation-1: -Endothermic reactions are the opposite of exothermic reactions. They absorb heat energy from their surroundings. This means that the surroundings of endothermic reactions are colder as a result of the reaction.

Detailed explanation-2: -An exothermic process results when heat energy is released, decreasing the internal energy of the system. If you touch a container that holds an exothermic process, it will feel warm or hot to the touch. One example of an exothermic reaction is the hot pack you made with sodium carbonate.

Detailed explanation-3: -Endothermic reactions are those that must absorb energy from their surroundings. This can include absorbing heat from the container they are in, or from your fingertips. The result is that both the container and your fingers will feel cold.

Detailed explanation-4: -Endothermic Processes These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes: Melting ice cubes. Melting solid salts. Evaporating liquid water.
