What use of erlen meyer flask?
an erlenmayer or what we called erlen in French is a material useful in chemistry .commonly known in English as a conical flask or E-flask, is a widely used type of laboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.Erlenmeyer flasks are used for pH titrations and in microbiology for the preparation of microbial cultures.
What would happen to the mass of the flask and its contents if the balloon was removed?
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 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.
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.
What Would You observe about the mass in the flask if you did not put a balloon on top of it?
If you did not put a balloon on top of the flask, you would observe the mass of the contents would likely decrease over time. This is because gases or vapors could escape from the flask, leading to a loss of mass as volatile substances evaporate. Additionally, any reactions occurring within the flask that produce gas could further contribute to mass loss. Overall, the absence of a balloon would allow for the exchange of matter with the surroundings, affecting the measured mass.
Examples of air exerts down ward pressure?
1. Put a little water (about 20 ml) in the flask and heat it to a boil. 2. Let the water boil vigorously for at least one full minute. 3. Take the flask off the hot plate and immediately place the balloon with the mouth over the flask's mouth. 4. Let cool slowly at room temperature (the balloon will be pushed inside out into the flask).
Why does a balloon fill with air when enclosed on top of a heating flask?
because the heat puts off air
What is a Erlyn-Meyer flask?
An Erlenmeyer flask is a type of laboratory glassware with a narrow neck and a conical body. It is commonly used for mixing, storing, and heating liquids in chemistry experiments. The design allows for easy swirling and mixing of liquids without spilling.
What would.you observe about the mass in the flask if you did not put the ballon on top?
If the balloon is not placed on top of the flask, the mass inside the flask would remain the same, but gas and vapors may escape into the air, potentially leading to a decrease in the overall mass if measured after some time. Additionally, any reactions occurring inside the flask might release gases or substances that could alter the mass. Without the balloon, it would be challenging to contain and observe changes in pressure or gas accumulation.
