(8pts) When you woke up this morning, you were surprised how beautiful it was outside since it had rained all night. Before leaving the house, your grandma mixed up some batter, sprayed the pan with a flammable substance, and cooked some fresh pancakes for you. Even though you wanted to see your friends, the pancakes smelled so good on the stove, you couldn't leave without eating at least one. Not to mention, your grandma put chocolate chips in them. The pancakes were delicious because all of the chocolate chips were gooey and melted. After eating, you quickly grabbed your favorite, fuzzy, yellow jacket and headed outside to meet up with your friends. Outside the grass was wet, but all the puddles on the sidewalk had evaporated. When you looked down the street, you could see all your friends riding their bikes. You ran to the backyard to grab your bike and noticed that one handle bar was red and rusted. Your mom had warned you how metal could oxidize when left in the rain. You jumped on your bike and rode off to catch up with your friends anyway trying to avoid all the cracks and potholes in the street. By the time you caught up with your friends, you had a terrible stomachache. Your stomach hurt so badly, for one second, you thought the pancakes were toxic, but then you remembered that you tried to wash them down with milk that had turned sour. Unfortunately, you had to head back home to take your temperature and get some rest. Hopefully, you can hang out with your friends tomorrow.

Label the parts for all the states of matter and phase changes that occur. Be sure to use your understanding of the properties of water when making your graph. Then sketch the particle structure in each jar to represent the proper state of matter.
