Today was our second lab and the point of it was to experiment the different states of matter. Andrew started class with teaching us about the different states of matter. The three main states of matter are a solid,liquid, and gas. He also taught us by combing the states created different stages such as melting, freezing, and vaporization. With the dry ice we would experiment with the different states of matter.
Today was an exciting day because we got the opportunity to experiment with dry ice. As a group we were given individual pieces of dry ice. Despite being called dry ice it was really extremely cold. Within seconds of touching it your hand would start to freeze. The dry ice was cold enough to the point where the water in the air condensed to water vapor which created a smoke effect. We also found out that it low resistance to the table. With a slight push it would elegantly glide through the table like an ice skater in the rink. To add to the experiment we added water to the mix. Within seconds of dropping it in the water it started to create CO2 which gave it a steamy effect. To take it to the next step we incorporated soap and string. To start off we had water in the beaker and added dry ice. With the string we dipped in soap and we glazed it over the top of the beaker. After it was glazed it would create a bubble. Overall the experiment was a fun way to observe the different states of matter.
After the balloon expanded from it's original state with the dry ice we had to find out the ratio between the two. Based on our observations the ratio between the deflated and inflated balloon was 1:3398.15. With these findings it tells me that when the CO2 sublimates the distance between the two expands to 3398 times it's original size.
