Did you know?

Exothermic and endothermic describe two types of chemical reactions or systems found in nature, as follows: After an exothermic reaction, more energy has been released to the surroundings than was absorbed to initiate and maintain the reaction. An example would be the burning of a candle, wherein the sum of calories produced by combustion (found by looking at radiant heating of the … WitrynaMelting is endothermic. Melting process needs energy to convert it from solid to liquid state. Ice melts when heat energy causes the molecules to move faster, breaking of hydrogen bonds between molecules to form liquid water.

Witryna5 wrz 2024 · Is melting ice endothermic or exothermic? Basically, when the ice consumes (heat) energy, which allows a transition to occur, melting ice is an endothermic response. The ice cube needs heat to melt, so the process is endothermic. What is an example of exothermic change? WitrynaOne of the most common endothermic reactions is the melting of ice. Heat is drawn in from the surroundings, triggers this reaction, and begins to break the chemical and …
