1. of or relating to a chemical reaction that absorbs energy from its surroundings; requiring energy input to proceed
Usage: chemistry; technical

Examples

• Photosynthesis is an endoergic process that converts light energy into chemical energy.
• The dissolution of ammonium nitrate in water is an endoergic reaction that absorbs heat.
• Endoergic reactions require continuous energy input to maintain the reaction.
• Unlike exoergic reactions, endoergic processes do not release energy spontaneously.
• The melting of ice is an endoergic phase change that requires thermal energy.
