  • I love cooking scrambled eggs, they are just so delicious!!
  • Well, do you know how the scrambled egg takes it form due to phase change?
  • No! But I would love to learn.
  • Well, it is quite simple. As the stove heats the eggs, the temperature of the eggs begin to rise also increasing the energy levels within the egg.
  • Well then how does the egg change from a liquid to a solid?
  • As the egg heats up and gains energy, it begins to change phases. During the phase change from liquid to solid, it does not change temperatures but energy is used to perform the phase change.
  • Exactly! Since it is so cold right now, let's do an experiment!
  • And it is just crazy how delicious scrambled eggs are!
  • Wow! I never knew how complicated of a process it is for an egg to be cooked! I assume the same happens with many other foods.
  • Let's leave this water bottle at room temperature for a couple hours.
  • Sounds good! I'm excited!!
  • What do you think will happen and why?
  • The water in the bottle will go through phase change and freeze becoming a solid. It does this because once it reaches the freezing point, it does not change temperatures, but uses the energy to transform from a liquid into a solid!
  • Exactly! The water went through phase change and became a liquid!
  • This will come in handy when you take chemistry! You will be an expert on how temperature, energy, and phase change are all connected!!
  • Wow!! You were right, it is completely frozen.
