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.
