Endothermic

If we look at the endothermic meaning, it is a type of reaction in which the system absorbs all the energy from its surroundings. As it is clear from its names, “endo” means “to absorb”, and “thermic” means “heat”. Examples are dry ice, melting ice, thermal decomposition and alkane cracking. This energy absorption happens due to the conversion of reactants into products due to the disassociation of the bonds between molecules. In such a reaction, the heat is taken up from the surroundings, so the temperature of the system where the reaction is taking place remains cooler. Also, the enthalpy, a change in the heat energy during the conversion of reactant to the products, is higher at the end of the reaction.
