Did you know?
Witryna11 kwi 2024 · Melting is an endothermic process as we need to apply external heat to a solid substance in order to make it melt. Heat is absorbed by the reactant species in the melting process and the change in enthalpy results out to be positive indicating the … WitrynaExothermic reactions are chemical reactions which release energy from the chemicals into the surroundings. This energy is usually released as heat, so the surroundings …

A reaction that converts thermal energy to chemical energy (heat is taken in) Endothermic reaction. Examples of exothermic changes. Combustion, neutralisation, displacement, condensation. Examples of endothermic changes. Witryna12 mar 2024 · Explanation: Water is a higher energy state, as the liquid can rotate and vibrate while solid ice can only vibrate. This means for ice to turn into a higher energy state (water) it has to absorb energy, hence it is an endothermic process with respect to the system (surrounding temperature decreases). Answer link.
