This lab was to learn about how things can change form depending on the temperature or pressure the substance is in. We learned that pressure determines how much distance molecules will move outward. One thing I didn't know was that solids, liquids and gas all can turn into each other when the right amount of temperature or pressure is applied. In the experiment we got to see dry ice sublimate, which means to turn into gas.
In the experiment, we got to play with dry ice. We dropped dry ice in water and then we saw that a whole bunch of gas was coming out of the water from the dry ice. We also put bubble soap into the water and with that mixture, we dropped the dry ice in it also. In that dry ice, instead of gas coming out of it, there were bubbles that held the gas in them. Another thing we did was put 2 centimeters of dry ice into a balloon to see how much gas would be produced from 2 centimeters of dry ice. The balloon would keep the gas in one spot so it is easy to measure.
With the 2 centimeters of dry ice in the balloon after a while, I measured the balloon again and it became a 24 centimeter high balloon. After doing all the math, I found out that the ratio of volume between the solid dry ice and the gas dry ice is 1:1728.0275, this means that with one unit of dry ice, it makes 1728.0275 cubic centimeters of gaseous dry ice. This ratio tells me that the molecules in a gas are more far apart from each other than the molecules in a solid, which are super close to each other. With this experiment, I learned that touching dry ice isn't as bad as every tells me and also playing with dry ice can be fun to play with.
