Lab: How To Crush The Can

The main objective of this experiment is to differentiate between a physical change and a chemical change.

reaction has taken place, for example a gad is given off or a solid is

It was known that a reaction had occurred as there was the formation of new substances from the existing elements such as hydrogen. This was an exothermic reaction as it produced heat which was another factor contributing to the increased reaction rate.

A chemical reaction is a process that involves change of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The key concepts of a chemical reaction are:

For example, in the experiment when I poured Hydrochloric acid in a test tube and then one magnesium ribbon, the substances started to bubble. Other than that, when I took the wooden split and lit it, I burned the green paper and it changed brown around the edges of the paper.

A chemical reaction takes place using displacement reaction between a metal and acid, for example when the hydrogen and magnesium react the

It’s predicted that when adding the chemical substance into the water, energy will be released or absorbed, this will be observed by a temperature change, therefore, there would be an exothermic or endothermic reaction.

The purpose of my investigation is that CanCo is looking to hire a team that can prove it able to effectively solve our technical research problems. I know that pressure can crush things.Pressure is applying force against an item.Air pressure is caused by the weight of air molecule pressing into each other. Temperature is a reason that can causes air pressure because if it's how the molecules will move faster rather if it was colder.The air collides outside which causes the can to crush and no longer the same force inside so the can get crushed. The specific relationship we are exploring is , will the can still crush even though we use another substance rather than just plain water. This interest me because we didn't want to use

So this is what keeps the air trapped when vertically held in water. The scientist then got another soda can and added water with an eye dropper. He put the can on the heater, the can instantly made the water from the eye dropper evaporate into water vapor. Then the scientist again and inserted the can into the water the results, the same with the can being full of

In the experiment of crushing the can through a series of actions taken, we’re left to watch it crush in action. So how exactly does it all happen from the start to finish? During the very start of it, the can and air around it was room temperature and so was the water in a container nearby. The boiling station were turned on and a soda can filled to about 20 mL of water, after a long while, it would begin to boil up when placed on those stations. The water particles have moved rapidly and split apart into vapor as the particles outside began to move faster than usual. The particles movement of the water made it into water vapor, filling up the can with water vapor. This replacement leaves no room for air to be in there and thus, the can

When carbonated gasses are put into a small bottle that's under pressure or sealed, and you shake the bottle the carbohydrate creates fizz, the fizz flows to the top as it is getting shaken. When you open up the bottle, all the air and fizz explodes, and all the bubbles and fizz comes out of the bottle.

Chemical change is when one substance touches another substance a reaction which is not able to be reversed back to the original state. One way to see chemical change is to light a match. The match will create charcoal which can not be turned back into wood so the charcoal has gone through chemical change.

In lab, to observe the effect of air pressure on an aluminum can, an experiment was conducted. To conduct this lab, my lab partner and I, began by rinsing an aluminum pop can and placing approximately 10 mL of water into the can. Next, we place the can on a wire screen supported by a ring stand, and heated the can with a bunsen burner. Afterwards, we filled a plastic bucket half full of cool water and observed the can until steam was visible. Finally, we picked up the can using tongs and turned the can over, placing the opening of the can under water in the bucket to observe the effect of air pressure on the can. When this lab was conducted, some of the water placed in the aluminum can vaporized and turn into water vapor, causing some air in

When you first look at the experiment you think it is a chemical reaction, but it is actually a physical reaction. The reasoning behind this is a process called nucleation. (Design, n.d.) Nucleation is a change of state; an example is solid to liquid. (Corporation, 2003) What causes this physical

Introduction: The theory behind this experiment is the heat of a reaction (∆E) plus the work (W) done by a reaction is equal to
