Question

1. which of the following is an example of an endothermic reaction? a. photosynthesis in plants b. burning wood c. lighting a match d. freezing water

Explanation:

An endothermic reaction absorbs heat from the surroundings. Photosynthesis in plants uses sunlight (energy) to convert carbon - dioxide and water into glucose and oxygen, absorbing energy. Burning wood, lighting a match are exothermic as they release heat. Freezing water is an exothermic phase - change process as heat is released when water turns to ice.

Answer:

a. Photosynthesis in plants
