INFORMATION:
We have two process:
- Cooking an egg
- formation of snow
And we must identify which process is exothermic or endothermic
STEP BY STEP EXPLANATION:
To identify it, we need to know that:
- Endothermic process is a process where heat is absorbed
- Exothermic process is a process where heat is released
So, to identify which process is exothermic or endothermic, we need to know if heat is absorbed or released.
- Cooking an egg:
In this process, the egg is colder than the boiling water in which it is cooked. So, to create a balance of temperatures, the egg absorbs heat from the water in an endothermic process.
- Formation of snow:
In this process, snow forms when ice crystals stick together and become heavy enough to fall to the ground. To create a balance of temperatures, the system would have had to release its internal heat to the environment because the environment is cooler than internal temperatures.
Finally, cooking an egg is endothermic and formation of snow is exothermic.
ANSWER:
Cooking an egg is an endothermic process because the egg is colder than the boiling water in which it is cooked, so it absorbs heat from the water to create a balance of temperatures. While on the other hand, the formation of snow is an exothermic process because the system would have had to release its internal heat to the environment because it is cooler than internal temperatures.
