What are the 6 characteristics of gas?
Gases have no definite shape or volume and expand to fill their container. They are highly compressible and tend to diffuse quickly. Gas particles are in constant, random motion. Gases have low densities compared to liquids and solids. They do not exhibit strong intermolecular forces. Gases are affected by changes in temperature, pressure, and volume.
Will starch diffuse across the cellophane membrane?
No because starch is a bigger and a complex compound
What type of compound would easily diffuse into the cell?
Small, nonpolar molecules such as oxygen and carbon dioxide can easily diffuse into the cell membrane due to their ability to pass through the lipid bilayer. Hydrophobic compounds also diffuse across the membrane more readily than hydrophilic compounds.
Do molecule diffuse faster in areas of high temperature?
Yes, molecules diffuse faster in areas of high temperature. This is because higher temperatures increase the kinetic energy of molecules, causing them to move and collide more frequently, which leads to faster diffusion.
Does helium come out of a balloon faster than air?
Yes. The reasons are helium is monoatomicand light and therefore at a particular temperature the helium atoms move faster and can diffuse out quicker than the larger molecules N2, O2 in an air filled balloon. (This is Grahams Law of gaseous effusion in practise)Gases are diffusing through theballoon membrane in both directions- the pressure difference is not really that great after all you can inflate a balloon using only lung power.Fill a balloon with a gas such as SF6 then it will inflateas the lighter faster moving air diffuse in at a higher rate than SF6 diffuses out
How does temperature affect the rate of diffusion?
The higher the pressure, the more easily a chemical diffuses. And seeing as pressure and temperature are directly related, the higher the temperature the more easily a chemical diffuses, and vice versa. This is caused by everything "wanting" to be equal, if there is a higher pressure, then it will diffuse to an area of lower pressure.
Does all gases diffuse the same speed?
No, all gases do not diffuse at the same speed. Factors such as molecular weight, temperature, and pressure influence the diffusion rate of gases. Lighter gases tend to diffuse faster than heavier gases.
Do hydrogen and oxygen diffuse?
Yes, both hydrogen and oxygen are gases at room temperature and pressure, so they can diffuse easily in air. Diffusion is the process by which gases mix due to the random motion of their particles.
What two properties does a solid compound will not have?
1-solids do not flow.2- they do not diffuse.
Which gas would diffuse most rapidly under the same conditions of temperature and pressure a large or a small one?
A small gas molecule would diffuse more rapidly than a large gas molecule under the same conditions of temperature and pressure because smaller molecules have higher average speeds and can move more easily through spaces between other molecules.
Why does a white ring form when ammonia and hydrochloric acid diffuse?
Both ammonia and hydrochloric acid are colorless gases at standard temperature and pressure, but they are capable of reacting with each other to produce ammonium chloride, which is a white solid at standard temperature and pressure. Colorless gases are invisible to human eyes, but white solids are not. When the two gases diffuse toward one another, they form finely divided white solids that remain visible for a while as a white ring in the diffusion interface.
What is the relationship of the partial pressure of a gas and its diffusion rate?
The higher the pressure, the more easily a chemical diffuses. And seeing as pressure and temperature are directly related, the higher the temperature the more easily a chemical diffuses, and vice versa. This is caused by everything "wanting" to be equal, if there is a higher pressure, then it will diffuse to an area of lower pressure.
What is grahams law of diffusion?
graham's law of diffusion states that the rates of which gases diffuse at the same temperature are inversely proportional to the square roots of their densities.
Will osmotic pressure be generated if solutes are able to diffuse?
Yes, osmotic pressure can still be generated even if solutes are able to diffuse. Osmotic pressure is a result of the concentration gradient of solute particles across a semipermeable membrane, and it is not affected by the ability of solutes to diffuse.
What will happen to the volume of a confined gas if the pressure is reduced provided the temperature is kept constant?
Imagine you have a small box inside a larger box, the temperatures are the same. If the smaller box contains high pressure gas, and you want to lower the pressure, you open the box. The same amount of gas has now diffused into the larger box. So I guess the answer to your question is that the gas will diffuse.
