An endothermic process is a chemical reaction or physical change that absorbs heat energy from its surroundings. These processes result in a decrease in the temperature of the surrounding environment.
5 Must Know Facts For Your Next Test
Endothermic processes require an input of energy to proceed.
Examples include melting ice, evaporating water, and photosynthesis.
The enthalpy change ($\Delta H$) for an endothermic process is positive.
In an endothermic reaction, the products have higher energy than the reactants.
These processes often feel cold to the touch because they absorb heat.
