Yes.
The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.
Endothermic reactions.
Endothermic reactions absorb energy in the form of heat from the surroundings. These reactions require energy input to proceed, usually resulting in a decrease in temperature in the immediate environment.
Endothermic reactions are chemical reactions that absorb free energy, typically in the form of heat. These reactions require an input of energy to proceed. Examples include photosynthesis and the melting of ice.
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
Endothermic reactionFor endothermic reactions Hfinal > Hinitial and DH is positive (+DH)It can be for example melting ice, or vaporising Rubbing Alcohol.---------Change of phases are not chemical reactions !
Yes, chemical reactions can absorb energy. This can occur in endothermic reactions, where energy is required for the reaction to proceed. Examples include the reaction of baking soda and vinegar, which absorbs heat energy.
An endothermic reaction.
The type of reaction that absorbs energy is endothermic. This process takes the energy from its surroundings, absorbs it, and creates heat.
Exergonic reactions.
Endothermic reaction
In an exothermic reaction, energy is released in the form of heat, making the surroundings warmer. In contrast, an endothermic reaction requires energy input from the surroundings to proceed, making the surroundings cooler as it absorbs heat.
