Used Of Cork stopper
1. Used Of Cork stopper
made of agglomerated cork in assorted sizes to hold beakers and other glass containers snuggly to ensure against breakage.furthermore laboratory cork rings are heat resistance and therefore withstand very high temperature allowing flask to be placed in the rings directly from bunsen burners.

Answer:
rubber
Explanation:
Because rubber is an insulator
9. what keeps the rubber stopper or a stone to move in circular motion?
Answer:
Basically, this is a mass on a string attached to a rubber stopper. The string passes through a glass tube
Explanation:
absence of the centripetal force, the object will not move in a circular path. Consider the example of a stone tied to the end of a string and whirled in a circle. ... string provides the necessary centripetal force that keeps the rubber stopper
10. Q1. Describe the motion of the rubber stopper.
Answer:
In today's lab a rubber stopper is connected to a string, and the rubber stopper is swung in a horizontal circle. The tension in the string causes the stopper to undergo centripetal acceleration. (If the string suddenly breaks, then the rubber stopper will move in a straight line in accordance with Newton's first law.
Explanation:
hope it helps

12. What is the centrepal acceleration of the rubber stopper
If an object of mass m is rotating with constant speed v. about a circle of radius r, then the centripetal acceleration on the object has the magnitude: a = v2/r.

13. What happens if the rubber stopper pulling weights are removed
Answer:
Friction and gravity will cause the rubber stopper to stop its motion. If the first stopper is turned loose while moving in a circular path, it will continue in a straight line until gravity and friction pulls it to earth.
14. A rubber stipper tied a string in travelling at a constant speed of 6 m/s in a circle or raduis 2m. what is the centripetal acceleration of the rubber stopper?
Answer:
18 m/s^2
Explanation:
a(centripetal acc)= velocity squared/ radius
a= (6)^2÷2
a=18
15. how do you safely heat a solution contained in a flask with a rubber stopper?
Answer:

16. how do you insert glass tube into a rubber stopper?
Explanation:
Lubricate the end of the glass tubing with a few drops of water, washing-up liquid, glycerol, or vegetable oil.
Hold the glass tubing close to where it enters the hole in the rubber stopper.
Ease the tubing into the hole with a gentle twisting motion.
17. what keeps the rubber stopper in circular motion?
Answer:
Friction and gravity will cause the rubber stopper to stop its motion. If the first stopper is turned loose while moving in a circular path, it will continue in a straight line until gravity and friction pulls it to earth. The force needed to keep an object moving in a circular path.

23. how do you insert glass tubing into rubber stopper?
Answer:
Inserting Glass Tubing
In many experimental procedures, you are required to insert a thermometer or a length of glass tubing into a hole in a rubber stopper. It is essential that you know the correct way to do this. Otherwise, serious injury may result.
Lubricate the end of the glass tubing with a few drops of water, washing-up liquid, glycerol, or vegetable oil.
Hold the glass tubing close to where it enters the hole in the rubber stopper. Protect your hands with work gloves or pieces of cloth (one method is to insert a cork borer (one size above the OD of the tubing) into the hole. The stopper is flexible enough to allow the cork borer to slide right in. Insert the glass tubing and position it appropriately. Then pull the borer back out. The glass tubing will stay in).
Ease the tubing into the hole with a gentle twisting motion. Push the tubing through the hole as far as is required. Do not use force!
Wipe excess lubricating material from the tubing before continuing with the experiment.
If the glass tubing is to be removed from the stopper, it should be done immediately after the experiment is completed.
