Here Is the Reason Why Dry Ice Makes Fog

Why you put a piece of dry ice in water, youll see a cloud of what looks like smoke or fog billow away from the surface and down toward the floor. The cloud is not carbon dioxide, but actual water fog.   How Dry Ice Produces Water Fog Dry ice is the solid form of carbon dioxide, a molecule that is found as a gas in the air. Carbon dioxide has to be cooled to at least  -109.3  °F to become a solid. When a chunk of dry ice is exposed to room temperature air it undergoes sublimation, which means it changes from a solid directly into a gas, without melting into a liquid first. Under ordinary conditions, this occurs at the rate of 5-10 pounds of dry ice converting into gaseous carbon dioxide per day. Initially, the gas is much colder than the surrounding air. The sudden drop in temperature causes water vapor in the air to condense into tiny droplets, forming fog. Only a small amount of fog is visible in the air around a piece of dry ice. However, if you drop dry ice in water, especially hot water, the effect is magnified. The carbon dioxide forms bubbles of cold gas in the water. When the bubbles escape at the surface of the water, the warmer moist air condenses into lots of fog. The fog sinks toward the floor both because it is colder than the air and because carbon dioxide is denser than air. After a time, the gas warms up, so the fog dissipates. When you make dry ice fog, the concentration of carbon dioxide is increased near the floor. Ready to try it yourself? Heres how to make dry ice fog, safely.

The American Prison System Is A Vital Portion Of American...

Merriam-Webster defines prison as a building where people are kept as punishment for a crime or while they are waiting to go to court. In the United States, there is a large prison system consisting of federal and state prisons. The American prison system is a vital portion of American culture.

The U.S. prison system is necessary; however, the curren t question is whether it is effective. The prison system should be reformed so that the prisons are not overcrowded and that prisoners have an improved quality of life in and out of prison. The biggest issue with prisons right now is that they are extremely overcrowded. This problem is attributed to the rising crime rate. Currently the crime rate is fairly high, â€Å"Nationwide, law enforcement made an estimated 11,302,102 arrests in 2013† (FBI). Not all of these arrests were sentenced prison time, nonetheless thousands were. 631,200 people were incarcerated in prisons last year (Carson). Several people argue that the crime rate is lower than it has been, however the best crime rate is 0. Prisons aid in lowering the crime rate because criminals cannot commit crimes while they are locked up and currently there are around 2 million criminals not committing crimes (Prisoners), nevertheless once those prisoners are released they return to a life of crime. Statistics show, â€Å"two-thirds of prisoners will reoffend† (Criminal Justice). One of the main roles of prison is to rehabilitate prisoners so that they will not commit other crimes; however, it obviousl y is not working. To alleviate this problem, prisons should counsel prisoners and educate them on why crime is

These are also inclusive of methods, measurement systems used for presentation of financial information in prepared statements.

Thus, business organisations are required to state these policies for providing a better understanding to users clearly (Gibson, 2012).
