'Cause You're Hot Then You're Cold
Today we learned about phase changes and took notes on phase changes :D.
So today, like on many days, I was eating chocolate! I had a chocolate chip cookie as soon as I got home because I am fat and while I was eating it my fingers got all sticky because the chocolate had begun to melt off. Basically, it was me eating for a few minutes and then noticing liquid chocolate on my fingers. I did not see the melting, but I did notice the sticky chocolate afterwards. But why does this very inconvenient situation occur whenever we eat chocolate?
The reason why our fingers get melted chocolate all over whenever we eat chocolate is because of phase changes and thermal energy. When you are holding the chocolate, the chocolate is most likely colder than you are and since objects like to be at equilibrium the chocolate and your body will try and match up in terms of heat. Also, heat always goes to the colder objects so your body heat transferred some of its energy to the chocolate. But the chocolate does not just take the heat and remain nice and thick, it begins to slowly melt off because of its temperature. Once the chocolate hits its melting point it'll begin to melt off.
Of course heat energy was added to the chocolate and part of the chocolate changed from a solid to a liquid. This transition is called "melting" and it occurs when an object hits the melting point.
But yes, chocolate! Make sure to eat veggies too if you don't already!! :DDD
Bye bye :3
