Background Research
A phase change is when a substance changes from one state of matter to another. In my experiment I will be freezing liquids, milk, raspberry lemonade, diet Pepsi, and water. Each of those liquids freezes and I will be melting them to see if what’s in them effects how fast they melt. When a solid melts to a liquid it goes through a phase change called melting. The normal freezing point of water is 0 degrees Celsius, so if the temperature is above that then ice will melt.

In order to see if what is in my liquids affects how fast they melt, I found out what’s is in them. Water is hydrogen and oxygen and that’s about it, but 1% milk is made out of protein, sugar, salt, fat, milk and vitamins A and D. Raspberry lemonade is made out of water, salt, sugar, lemon juice and raspberry puree. Diet Pepsi is made from salt, carbonated water, caramel color and caffeine. Ceramic plates are what I am melting them on because it wouldn’t soak up the melted ice. Ceramic plates are made of natural or specially formulated clay. I am melting these four liquids from their solid forms and am seeing which one melts the fastest.
