Final answer:
Processes like water boiling, gasoline burning, and ice forming are classified as endothermic and exothermic based on whether they absorb or release heat. Water boiling is endothermic, while gasoline burning and ice forming are exothermic.
Step-by-step explanation:
Classification of Processes as Endothermic or Exothermic
Label each of the following processes as endothermic or exothermic:
- Water boiling: This is an endothermic process because it absorbs heat from the surroundings to convert liquid water into water vapor.
- Gasoline burning: This is an exothermic process as it releases heat into the surroundings when gasoline combusts.
- Ice forming on a pond: This is an exothermic process because it releases heat into the environment as water changes from a liquid to a solid state.
Understanding whether a process is endothermic or exothermic is crucial for comprehending how energy is transferred between systems and their environments.
This concept is fundamental in the study of thermodynamics in chemistry, influencing various daily life processes such as cooking, heating, and even natural phenomena like the freezing of water.
