How 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.
What is the crushing can experiment?
When the can was flipped into a pool of ice cold water, the can collapsed on itself. 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!
What can implode?
Examples of implosion include a submarine being crushed from the outside by the hydrostatic pressure of the surrounding water, and the collapse of a massive star under its own gravitational pressure.
Why do cans implode in cold water?
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 does a hot can implode in cold water?
Can on hot plate experiment?
Place the can directly on the burner of the stove while it is in the “OFF” position. It’s time for that adult to turn on the burner to heat the water. Soon you’ll hear the bubbling sound of the water boiling and you’ll see the water vapor rising out from the can. Continue heating the can for one more minute.
Why does the can implode?
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.
Can you boil water in a can?
Use the can to heat your water. To make yourself feel better, boil several batches of water and pitch it. Lat’s say all the nasties have been boiled out of it. Feel good about using it from then on.
Can Crusher Charles Law?
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.
How do you calculate the volume of an imploded can?
Empty the water from each can, then determine each of their volumes by filling them with water from a graduated cylinder. Plot the volume of the imploded cans on the y axis verses the temperature of the water in the cans on the x axis. Have students determine if there is a relationship between these variables, and if so, why.
How do you heat up an imploded can?
Heat 20 mL of water to boiling inside each can, but change the temperature of the water bath by 25° increments for each; for example, 0° C, 25° C, and 50° C. Invert and submerge each of the cans in the water bath at the given temperatures above. Repeat step 4 from Activity 2 above to determine the volume of each imploded can.
How do you implode an aluminum can?
With beaker tongs, quickly invert and submerge the can, mouth down, in the ice water bath. Use 3 additional empty aluminum cans for each of the activities that follow. Heat the 20 mL of water in each can at 10° intervals of 80° C, 90° C, and 100° C. Invert and submerge each in an ice water bath at 0° C. Observe the amount of implosion for each.
How does temperature affect the volume of an imploded can?
As the temperature of the water inside of the can gets higher, the volume left in the can after the implosion is less. This is because more water vapor condenses when it is submerged, creating a greater implosion. Plot the volume of the imploded cans on the y axis versus the temperature of the water bath on the x axis.
