Why gas particles diffuse more slowly through aluminum that through rubber?

Gas particles diffuse more slowly through aluminum than through rubber because aluminum has a higher density and more closely packed structure, which impedes the movement of gas particles. In contrast, rubber has a more porous and flexible structure that allows gas particles to move more freely and diffuse more quickly.


Why does air seep out of balloons when there are no holes in it?

All gases will diffuse through rubber to a certain extent. The difference in pressure for the helium between the inside and outside is 1 atmosphere and so it diffuses out. Note that the difference in pressure for the air between the outside and inside is also 1 atmosphere and so the air diffuses in. You can buy high quality balloons so that this does not happen as rapidly.


Why aluminum reacts so slowly with copper sulphate?

Aluminum reacts slowly with copper sulfate because aluminum is more reactive than copper. When aluminum reacts with copper sulfate, it forms aluminum sulfate and copper. This reaction can be slow because a layer of aluminum oxide may form on the surface of the aluminum, inhibiting further reaction.


Which light metal is slowly replacing aluminum in aerospace industry?

Titanium


Why does aluminum react slowly even though it is a very reactive metal?

Aluminum is very reactive but it appears to react slowly because first it reacts with air which makes a thin coating of aluminum oxide which has to wear away before there will be any visiual reaction.


Which is an example of gas effusion?

One example of gas effusion is the release of a gas through a small hole in a container, such as when air slowly escapes from a balloon. Another example would be the diffusion of gas molecules through a porous membrane, like the way oxygen and carbon dioxide diffuse in and out of our lungs during respiration.


What is a material through witch an electric charges moves slowly?

A material through which electric charges move slowly is called an insulator. Insulators have high resistance to the flow of electric current, which causes the charges to move at a slower speed compared to conductors. Examples of insulators include rubber, glass, and plastic.


What do you call a material that transfers heat slowly?

A material that transfers heat slowly is called an insulator. Insulators have low thermal conductivity, which means they do not allow heat to pass through them easily. Examples of insulating materials include wood, plastic, and rubber.


How can I effectively drill through aluminum to achieve precise and clean results?

To effectively drill through aluminum for precise and clean results, use a sharp drill bit specifically designed for metal. Secure the aluminum firmly in place and start drilling at a slow speed to prevent overheating. Use cutting fluid or lubricant to reduce friction and keep the drill bit cool. Go slowly and steadily to avoid damaging the aluminum and achieve a clean finish.


Which of the following diffuse faster - honey sugar nitrogen gas?

Nitrogen gas will diffuse the fastest because gases diffuse more rapidly than liquids or solids due to their higher molecular speeds and lack of intermolecular forces that impede diffusion. Honey and sugar are viscous liquids and will diffuse more slowly due to their higher molecular weight and stronger intermolecular forces.


How do you prick a balloon with out popping it?

To prick a balloon without popping it, you can use a needle or a sharp pin and gently insert it into the thickest part of the balloon where the rubber is most stretchy. Slowly push the needle through while holding the balloon tightly to release the air slowly, preventing it from popping.


Why does glucose diffuse into your blood more slowly when your muscles are working?

because when we work more enery is released and thats the reason for gulcose to dislove faster in the body .
