How does blowing air through a funnel pick up a ping-pong ball?
I think you're referring to the funnel apparatus where the large end of the funnel is pointed down. The funnel itself is just a little larger than the ping-pong ball. Air is blown through the funnel downward towards the ping-pong ball, but the ball doesn't drop. Instead it is held fast inside the funnel. The explanation lies with the Bernoulli Principle. This principle states that along any streamline of air (a streamline is the path that an air molecule takes), if the velocity of the air drops then the static pressure at that point will rise, and vice-versa. So what happens with the funnel and ping-pong ball is that the air coming out of the funnel has to flow around the ball and therefore it becomes constricted against the sides of the funnel. It doesn't have much room to get by, in other words. That means it has to flow faster over the top of the ball. Faster = lower pressure. When it gets by the ball and expands in the funnel, it slows down. Slower = higher pressure. This pressure difference (high pressure below, low pressure above) is what keeps the ball suspended in the funnel.
Why is carbon dioxide not considered a an organic compound?
Carbon dioxide is not considered an organic compound because it does not contain hydrogen atoms bonded to carbon atoms. Organic compounds are defined as compounds that contain carbon-hydrogen bonds. Carbon dioxide consists of one carbon atom bonded to two oxygen atoms, with no carbon-hydrogen bonds present. Organic compounds are typically associated with living organisms, while carbon dioxide is a simple inorganic molecule commonly found in the atmosphere.
How does carbon become part of organic molecule?
In living organisms, carbon fixation (incorporation of atmospheric inorganic carbon dioxide into organic compounds) is carried out by certain microbes and most plants and the other organisms feed on plants to acquire their organic compounds. The process of carbon fixation is called photosynthesis and it's driven by sun light and catalyzed by enzymes. In organic chemistry labs, chemists have found ways to either create organic molecules from inorganic ones or add carbon onto preexisting organic molecules, though these processes require very strigent reaction conditions that are different from those in living organisms, mostly because we cannot make use of enzymes the same way as living organisms do. The earliest experiments involved reacting carbon dioxide and ammonia by adding an electrical current, making urea as the product. Current organic chemstry techniques have countless ways to manipulate organic compounds and it will be futile to try to list even a fraction of the techniques. Follow the link below for a Wikipedia page that has links to a large number of possible organic chemistry reactions.
What is the method of separating oil from vinegar?
You need a separating funnel, which is kind of transparent cone with a valve below. The vinegar will exit from the bottom. Then the oil may be washed with water to further clean it.
How do you separate broken Glass water and salt?
You filter the mixture using a filter paper. By this the salt solution will get separated from glass bits. Then you take the salt solution and heat it. The water will get evaporated leaving salt behind.
What is funnel and how is it uses?
The separating funnel is used for the separation of liquids from a two phases solutionÈ™ after decantation the liquid from the bottom is released in a beaker. For images see the link below.

Funnel used to separate solids from liquids?
A Buchner funnel is commonly used in laboratories for separating solids from liquids through vacuum filtration. It consists of a perforated plate and a flask below to collect the filtrate, which allows for the liquid to pass through while retaining the solid material on the plate.
What is a stemmed funnel?
A funnel with a long stem (the straight part below the cone shaped part)
What is a long stem funnel?
A funnel with a long stem (the straight part below the cone shaped part)
what is a good sentence for funnel cloud?
The funnel cloud spun menacingly across the horizon, casting a shadow of fear over the town below.
How do you identify a funnel cloud?
A funnel cloud is a funnel, cone, or trunk shaped cloud that extends downward from the cloud base and rotates. If dust or debris can be seen swirling beneath it, that means a tornado is con the ground. Below are pictures of some funnel clouds.
What is collected in a beaker below a filter funnel after filtering?
The liquid, called the filtrate, passes through the filter funnel and is collected in the beaker below. The solid particles that are left behind on the filter paper make up the residue.
What supports exist for teens whose parents are separating?

Show me a diagram of funnel experiment in the preparation of hcl?
I'm unable to display diagrams in this format. However, in the experiment to prepare hydrochloric acid (HCl) using a funnel, you would typically mix hydrochloric acid (HCl) and water in a beaker, place a funnel over another container, and pour the solution through the funnel to separate any impurities or undissolved solids. The pure HCl solution would then pass through the funnel into the container below, leaving impurities behind.
What does it mean to say a mineral is organic?
An organic mineral is of biogenic origin; for example petroleum can be considered an organic liquid mineral. For other organic minerals see the link below.
Is organic farming the same as organic compound?
No. Organic farming is a method of farming for which no synthetic chemicals are used. This includes fertilizers and all types of pesticides. An organic compound is a substance.No. As said below organic faming uses no man made chemicals and organic compounds are carbon based.
