*POP* The Balloons attack?

Good afternoon readers, today we have another user submitted question. This user asks, "Why did my balloon pop when I left it inside my car during the summer?" That, my friend, is a good question. This can be explained using Charles's law concerning gas. Charles's law states that higher the temperature of the gas the higher the pressure and the lower the temperature of the gas the lower the pressure. In other words, the temperature of a gas and the pressure are directly proportional. So, when left in a hot car the gas inside the balloon expands and the balloon pops. 

*Ding* *Ding* Lucky day for you readers because for today I have two questions that need answering.The second user asks, "What is the science behind the valve on the gas cylinder?" Well, my friend Robert Boyle might just have an answer for you. Boyle's law concerning gas states that as the pressure goes up, the volume goes down and as the pressure goes down the volume goes up. In other words, the pressure and the volume are inversely proportional. So, in order to get the gas out of the gas cylinder, the pressure must be increased using the valve and a small hole must be made. This way as the pressure increases, the volume decreases and the gas will want to go out of the small hole and into a new container. Using this method, the rate at which the gas is moved out can be regulated by the amount of pressure being applied.

How to walk on Water

Okay, so today have I received a question from a reader. The reader asked, "What is the science behind dissolved cornstarch in water and why is it hard even though it is a liquid?" Well, to begin I will explain what happens when cornstarch is dissolved in water to those readers who did not know. When cornstarch is dissolved in water a substance is made that will turn solid if moved across quickly. The reason behind this is because of how the cornstarch acts as a solid dispersed throughout a liquid. When you apply force to the mixture the water is hit out of the way and all you are hitting is the solid, the cornstarch. This can be explained by explaining the states of matter. I will only be explaining the three most common states of matter and will be excluding plasma and Bose-Einstein condensates in order to simplify the process. The three main states of matter are solids, liquids, and gases. A solid has a definite shape and volume, an example of a solid is gold. A liquid has a definite volume but no definite shape, an example of a liquid is water. A gas has no definite shape or volume, an example of a gas is oxygen. Since water has no definite shape then it will spread to fill as much of an area as it can take up. However, a solid will not move out of the way and will stay rigid when hit. So, while the water moves out of the way to fill the rest of the container, the solid stays still and allows it's self to be hit.  

Slippery Days

Hey guys this is the first post I'm making on this blog  and I'm hoping you'll hear me out. Okay, so today I was walking home from school and I happened to trip on a long diagonally slated chunk of ice. I noticed how instead of just being on long chuck the ice was instead slanted downwards toward the street and was collected most on the curb. So, I decided to do some research of my own in order to find out why this was happening. I found out that the reason the ice was like that was due to how it changed states of matter. Through my research I found that the original substance that collected in that very spot was liquid water. The water collected near the curb stayed as a liquid at first but than froze and became a solid because it had ended up hitting its freezing point, or the temperature at which it turns into a solid. Now, because of that the ice has ended up collecting on the curb and slanting downwards toward the road just like the liquid water once did. From this research I have also concluded that a change in state is a physical change that happens to a material after a change in thermal energy. I have posted the video I used to help me come up with this conclusion up above. Thanks for reading and if you have any questions then make sure to ask at FakeEmail@FakeEmail.com.
