Chemistry

Sublimation and the states of matter are a part of chemistry in science. The three main states of matter in science are the solid state, liquid state, and the gas state. The states have different properties, to each other which can be explained by looking at their particle arrangements. The states of matter make up everything in the world. There are also two other states of matter that are less common in today’s world, which are known as Plasma and Bose-Einstein condensate. Sublimation is one of the many transitions from one state of matter to another. Sublimation is the transition of a substance straight from the solid state to the gas state, without passing through the liquid state of matter.

Something interesting happens when detergent is applied to dry ice. Carbon dioxide is a gas when it warms up and is the substance that makes up dry ice. Therefore, as the dry ice warms up, gas is released. When combined with water, the detergent aids in creating bubbles. The gas that is released when the detergent and dry ice are combined creates a lot of bubbles. These bubbles have the appearance of a bubble waterfall or a hazy cloud. Because of the chilly gas, the water in the air condenses into small droplets, giving the appearance of fog. It's entertaining and amazing to see, especially in shows or during science experiments.

This is what happened when we put metal on dry ice. When we put the metal on the dry ice the metal started frosting and it started making a noise that sounded like screaming. When we started forcefully pushing the metal into the dry ice the matter of the dry ice started to evaporate into carbon dioxide. This is called sublimation, which is when a solid changes to gas without going through the liquid phase.
