When the can is placed in cold water upside down, the hot gas water molecules are cooled very rapidly. This decreases the pressure inside the can. Since the air pressure outside the can is stronger than that inside the can, it causes the can to collapse.
Why did the can crush in the experiment?
What caused the can to collapse? When you heated the can you caused the water in it to boil. Cooling the can caused the water vapor in the can to condense, creating a partial vacuum. The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it.
Why does the collapsing can experiment work?
Since the water and air on the outside of the can is cooler than the steam inside, the steam condenses into a few drops of water. The drops of water on the inside of the can can’t exert the same amount of pressure as the water and air outside that can, so it collapses.
Can crushing experiment gas Law explanation?
When the can is filled with water vapor, the pressure inside the can is greater than the pressure on the outside of the can. When immersed in water, the water seals the opening and the vapor inside the can condenses, thus reducing the pressure inside the can and causing the can to be crushed.
Why were the cans crushed when they were placed in cold water explain what is occurring on a molecular level?
When the can is placed in cold water upside down, the hot gas water molecules are cooled very rapidly. This decreases the pressure inside the can. Since the air pressure outside the can is stronger than that inside the can, it causes the can to collapse.
Why did the can seemingly crush itself after submerged in cold water what forces are demonstrated here?
When the inverted can is placed in cold water, the steam condenses, leaving the can mostly empty, and thus with a very low pressure inside of it. The difference between the low pressure inside and the atmospheric pressure outside exerts an inward force on the walls of the can, causing it to implode.
Why do hot and cold water not mix?
That’s because these liquids have different densities. Whenever you put together two liquids that don’t mix, the liquid that is less dense will float on top of the denser liquid. So hot water is less dense than cold water.
Can you crush water?
The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. For that reason, liquids and solids are sometimes referred to as being incompressible. You probably have experienced compressing something as hard as steel.
Why was the can crushed symmetrically on all sides?
The reason for this is that the volume difference between heated and cooled steam is much greater than the volume difference between heated and cooled air. Therefore, when the can with the water is cooled, there is more of a pressure difference than if there is just air, and the can is crushed to a greater degree.
Why is it necessary to immerse the flask both in hot and cold water for 5 minutes before taking the temperature?
Why is it necessary to immerse the flask both in hot and cold water for 5 minutes before taking the temperature? The water levels inside and outside the flask when it was submerged in cold bath must be equal before the flask is removed.
Why does air pressure not crush a human?
Air does not crush you down. Fortunately, there is typically just as much pressure inside your body pressing outward as there is air pressure outside your body pushing inward. They typically cancel out, meaning that there is no overall force on you and you don’t get crushed.
How does can crush work?
When the soda can is plunged into cold water, the vapor condenses quickly, leaving a vacuum in most of the can. The resulting large discrepancy between the outside and inside air pressure leads to a large net inward force on the can, ending with its rapid crushing.
How much force does it take to crush a soft drink can?
An actual testing of the beverage can crusher of the present invention, 50 pounds was the maximum force input required to fully crush a seamed steel beverage can whereas the force required to crush all aluminum beverage cans ranged from 5 pounds to 20 pounds.
Is boiling water a gas law?
Gay-Lussac’s Law in Everyday Life As the temperature of the liquid water is increased, water vapour (water in its gas state) is produced. This vapour cannot escape the pressure cooker – meaning the volume is not changing.
Can crushing experiment conclusion?
Conclusion: The heating of the can turned some of the water into water vapor. The water vapor that was left inside the can quickly cooled and condensed into water droplets, creating a vacuum. Suddenly the pressure outside the can is greater than inside the can, causing it to collapse on itself!Apr 14, 2020.
Why did the can implode?
When you heated the can, the water inside turned to water vapor and began pushing on all sides of the can and eventually escaping. When the can was moved to the cold water and submerged, the water vapor inside condensed and no longer pushed on the walls of the can.
Can Crusher physics?
The can crusher is a giant electromagnet. A wire comes from the capacitor, which is like a big battery. Then the wire wraps around in a coil to make an electromagnet. The coil becomes a very strong magnet when the can crusher is turned on.
Can crushing experiment introduction?
Introduction: This experiment will show students one example of differences in pressure in the environment. By heating aluminum cans and subjecting them to a colder environment, a vacuum effect will be created inside the can. This will instantly crush the can without having to touch it!.
