If the balloon was removed from the flask, the mass of the flask and its contents would remain the same because the air inside the balloon is still part of the system. Removing the balloon does not change the total mass of the system.

Why is the glass shell on a flask a poor conductor?

The glass shell on a flask is a poor conductor of heat because glass is an insulator, meaning it does not easily transfer heat. This property helps to maintain the temperature of the contents inside the flask, whether hot or cold. Additionally, glass is a brittle material, so the shell acts as a protective barrier for the contents of the flask.


Why do the inner surface of thermos flask kept shiny?

The shiny inner surface of a thermos flask helps to reflect heat back into the flask, reducing heat transfer to or from the contents. This helps to maintain the temperature of the liquid inside the flask for a longer period of time.


How does the mirror coating prent thermos flask lose heat?

The mirror coating on a thermos flask prevents heat loss by reflecting infrared radiation back into the flask. The mirror coating acts as a barrier that reduces heat transfer between the contents of the flask and the surrounding environment, helping to keep the contents hot or cold for longer periods of time.


What the conduction in thermos flask?

Conduction in a thermos flask is minimized through the use of a vacuum layer between two walls of the flask. This vacuum layer prevents heat transfer by conduction, as there are no molecules present to transfer the heat. This helps to keep the contents of the flask hot or cold for an extended period of time.


How does the cork of the vacuum flask reduces heat?

The cork in a vacuum flask acts as an insulator, minimizing the flow of heat between the inside and outside of the flask. This helps to maintain the temperature of the contents by reducing heat transfer through conduction and convection. The cork creates a barrier that traps air and prevents heat from escaping or entering the flask efficiently.

What is a divided flask?

A flask with two chambers. The contents are kept separate from each other until the experiment is set to begin. To mix the contents the flask is shaken.


Why is the student unable to blow up a balloon in the flask?

The student is unable to blow up a balloon in the flask because there is already air present in the flask, creating a high pressure environment. When the student tries to blow air into the flask, the pressure inside the flask increases, making it difficult for air to enter and inflate the balloon.


What happens when a thermo flask contains some ice cubes?

The ice cubes will help to keep the contents of the thermos flask colder for a longer period of time. The thermos flask's insulation will prevent heat transfer from the surroundings, helping to maintain the temperature of the ice cubes and the contents of the flask. Over time, the ice cubes will melt and help to cool the contents of the flask.


How do you make a balloon reverse it's position without anyone touching it so that it inflates outside the flask rather than inside the flask?

Once again, heat the flask with the balloon on the inside. The cooled molecules will speed up again, creating energy. If the flask is left on the heat, the air pressure will grow, causing the balloon to be pushed back to the outside of the flask.


What would you observe about the mass in the flask if you did not put the balloon on top?

If the balloon is not placed on top of the flask, the mass inside the flask would remain constant. The balloon is used to capture any gases produced during a chemical reaction, which would otherwise escape into the environment. Without the balloon, the mass of the gases released would not be accounted for, leading to inaccurate measurements of the total mass change in the system.


Why did the temperature rise in flask a?

The temperature in flask A rose because heat was transferred from the surroundings to the contents of the flask, increasing the kinetic energy of the molecules and causing their temperature to increase.

What affect will water on the outside of the flask have in determining the density?

Water on the outside of the flask will not affect the density measurement of the contents inside the flask because density is a property intrinsic to the material being measured and is not influenced by external factors like water on the surface. To determine the density of the contents, only the mass and volume of the material inside the flask need to be considered.

What would happen if the neck of the sterilized swan-necked flask were broken?

If the neck of a sterilized swan-necked flask were broken, the flask would be exposed to contaminants in the air, negating the purpose of the swan neck design to prevent microbial contamination. This would likely compromise the sterility of the contents in the flask, leading to potential contamination and spoilage of the culture inside.


How many times should you invert a florence flask?

Typically, a Florence flask is inverted 3-4 times to ensure thorough mixing or agitation of the contents.


How do you use the word flask in a sentence?

You should always be cautious when heating chemicals in a flask. The glass flask containing phosphoric acid was soon leaking its contents onto the floor.
