If it takes sulfur dioxide gas SO2 20 seconds to diffuse from a container how long will it take helium gas He to diffuse from the same container?
It will take helium gas (He) less time to diffuse than sulfur dioxide gas (SO2) due to its lower molecular weight. Diffusion rate is inversely proportional to the square root of molecular weight, so helium will diffuse faster than sulfur dioxide. Therefore, helium will likely diffuse from the container in less than 20 seconds.
Where is water moving from in osmosis?
Water moves from an area of higher water concentration (dilute solution) to an area of lower water concentration (concentrated solution) in osmosis. This movement occurs across a semi-permeable membrane.
How does diffusion differ from osmosis?
Diffusion is the passive movement of molecules from an area of high concentration to low concentration, while osmosis specifically refers to the movement of water molecules across a semi-permeable membrane. Osmosis involves the movement of water to equalize solute concentrations on both sides of the membrane, while diffusion can occur with any type of molecule.
Why would oxygen diffuse much faster in air than water?
Oxygen diffuses faster in air than in water because air has lower density and viscosity compared to water. This results in less resistance to the movement of oxygen molecules, allowing them to travel more quickly through the air compared to water. Additionally, the concentration of oxygen in air is higher than in water, further facilitating the diffusion process.
Is diffusion of water is called osmosis?
Yes, osmosis is defined as the net movement of water molecules from an area where they are highly concentrated to an area where they are less concentrated across a semi-permeable membrane such as a cell surface membrane.
Does water diffuse towards an area with more salt or less salt?
water follows sodium
Does water tend to diffuse from a region where it less concentrated to a region where it is highly concentrated?
No. Water tends to diffuse from a region where it (water) is more concentrated to a region where it (water) is less concentrated. The other way of thinking about this is that water diffuses from an area of high solute concentration to an area of low solute concentration.
Is it true that water tends to diffuse from a region where is is less concentrated to a region where it is highly concentrated?
true
Does water tend to diffuse from a region where it is less concentrated to a region where it is highly concentrated?
Maybe you mean osmosis?However, osmosis is not the same as diffusion of water. Diffusion of water is just diffusion like with any other substance: the particles spreading, making a homogeneous distribution. Osmosis involves a semipermeable membrane, where water goes from low solvent concentration to high solvent concentration.answ2. However, in the oceans, the turbulence is very much less than that of the air. Thus whilst C14 for example diffuses reasonably rapidly in the air, and may be assumed to homogenize after a few years; in the oceans the rate of diffusion is very much slower.And the oceans are known to stratify. For example in the Fiords in New Zealand, there forms a fresh water layer on top of the sea water, and this is known to freeze in winter. The ocean water itself in the same locale never gets cold enough to freeze.
Does water diffuse from a region where its less concentrated to a region where it is highly concentrated?
No, it goes from HIGH concentration, to LOW concentration
Nutrients diffuse quickly through cartilage matrix but very poorly through solid bone matrix true or false?
True. Cartilage matrix is avascular and has a high water content, allowing nutrients to diffuse quickly. In contrast, bone matrix is solid and less permeable, so nutrients diffuse less efficiently through it.
Will ethanol float or sink?
Ethanol is less dense than water so it will initially float on a water surface. Given that ethanol is totally miscible with water, an ethanol layer on top of a water layer will diffuse into the water while the water will diffuse into the ethanol until a single uniform composition solution of alcohol and water is achieved.
What is the transport mechanism where a passive process pulls water from an area where there is more water to an area where there is less water?
osmosis
When water moves from an area where there is more water to an area where there is less water then the process is called?
When water moves from an area where there is more water to an area where there is less water, the process is called osmosis. Osmosis is the movement of water molecules across a selectively permeable membrane from a region of higher concentration to a region of lower concentration.
Why do clouds stay more or less intact and not diffuse into a haze?
Clouds stay more or less intact due to the natural force of water cohesion. As long as the air is saturated, the molecules forming the cloud will not disperse.
What happens to humidity when more water evaporates?
For water, higher humidity decreases evaporation because more water is present in the atmosphere. Less water will diffuse into the atmosphere. If it's at 100% humidity, there's no net evaporation.
Is it true that water tends diffuse from a region where it is lees concentrated to a region where it is highly concentrated?
It is not true. All substances tend to diffuse from an area of higher concentration to that of lower concentration. This is called passive transport(no energy required), or in the case of water, Osmosis. However, if given energy, they can also move from an area of lower concentration to that of higher concentration. This process is called active transport.
