Question

Which of the following is an endothermic reaction? Group of answer choices Energy in the form of heat, light, and sound are released when fireworks are ignited When two liquids, each having a temperature of 25oC, are mixed, the temperature changes to 55oC A puddle evaporates quickly on a warm day. Wood burns in the presence of oxygen, producing heat and light

Answer 1

The endothermic reaction among the options provided is the evaporation of a puddle on a warm day, where the puddle absorbs heat from the environment to change from a liquid to a gas.

Step-by-step explanation:

The question asks which of the provided scenarios is an endothermic reaction. An endothermic reaction is characterized by the absorption of heat from the surroundings, leading to a decrease in the temperature of the surroundings. The example that fits this description is: 'A puddle evaporates quickly on a warm day.' During evaporation, the puddle absorbs heat from the environment, which is required for the water to change from a liquid to a gaseous state. This absorption of heat makes the process endothermic. In contrast, the other scenarios describe exothermic reactions where heat is released into the surroundings, as in the case of fireworks and wood burning, or the mixing of two liquids resulting in an increase in temperature.
