Phases of Matter WorkSheet #2

         1) "Each substance has its own boiling point." ELI5: How could you use the information from this statement to separate a mixture of two liquids into two more pure liquids? 
Some liquids boil faster than others. If you boil two liquids enough, one liquid will evaporate out of the pot. There is a certain boiling point for each substance. If it becomes hot enough that one liquid will evaporate and you will be left with one liquid.
2) A pressure cooker is used to cook foods faster by increasing the pressure in a chamber. ELI5: How does this work?
A pressure cooker is a sealed pot with a valve that controls the stream pressure inside. As the pot heats up, the liquid inside forms steam, which raises the pressure in the pot. By raising the pressure the liquid heats up the molecules it has in it, and moves faster and farther apart, which will become into steam. This high pressure makes the steam raise to the boiling point of the water in the pot.
3) Snow is not made by rain freezing, but rather by a process of deposition. ELI5: How and why does this occur?
Deposition occurs when sediment transportation are no longer sufficient to overcome the forces of particle weight and friction. When its wet in the mountains and its cold, the moist becomes to form little crystals in the atmosphere, also known as the air. When these tiny ice crystals collide they stick together in clouds to become snowflakes. If enough ice crystals stick together, they’ll become heavy enough to fall to the ground. Then we will have snow, and make snowmen and snow angels.
