Endothermic VS Exothermic process Endothermic and exothermic processes are two types of chemical reactions or physical changes that differ primarily in the energy transfer that occurs during the process. ### Endothermic Processes 1. **Definition**: An endothermic process absorbs energy (usually in the form of heat) from its surroundings. 2. **Energy Change**: The energy absorbed results in a decrease in temperature in the surrounding environment. 3. **Examples**: - Photosynthesis: Plants absorb
