Melting is endothermic
A process can be classified as exothermic or endothermic. Without performing actual experiments, we consider a reaction to be endothermic if we need to supply heat to make the reaction occur or if we observe that the species’ temperature has decreased (beakers turn cold). Melting is considered to be an … Meer weergeven The heat content of a system is called enthalpy. Heat is a form of energy. The energy changes during the reaction can be expressed by a change in enthalpy. Change in … Meer weergeven The word “endo” has been derived from the Greek language, and it means “inside.” It is a type of chemical reaction in which reactants … Meer weergeven The reacting species absorb energy equivalent to the energy required to proceed with the reaction and form a transition state. The transition state then leads to desired product formation. The events during … Meer weergeven The word “Exo” has been derived from the Greek language, which means “outside”.
