01
a chemical process that absorbs heat energy from its surroundings, often resulting in a temperature decrease
Example
The endothermic reaction between barium hydroxide and ammonium thiocyanate absorbs heat, resulting in a temperature drop.
When ammonium nitrate dissolves in water, the endothermic reaction causes the solution to cool.
Photosynthesis is an endothermic reaction where plants absorb sunlight to convert carbon dioxide and water into glucose.
In a chemical cold pack, the endothermic reaction between water and ammonium nitrate absorbs heat, providing a cooling effect.
Melting ice is an endothermic reaction because it absorbs heat from its surroundings to change from solid to liquid.
