What is the meaning of Pinocytosis?
What is the meaning of Pinocytosis?
fluid endocytosis
Where does osmosis occur in the human body?
Osmosis is the movement of water from areas of high concentrations to lower concentrations across a semi permeable membrane. It occurs over these membranes in cells of the body alllowing water to move into and out of them.
What’s an example of diffusion?
Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored.
Which gas diffuses the fastest?
The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium.
Which diffuses faster liquid or gas?
Gases diffuse faster than liquids. This is because the particles of gases are much farther apart from one another as compared to the solids and liquids.
Which diffuses faster air or oxygen?
Oxygen gas diffuses faster. Because air being a mixture of gases is heavier than oxygen gas.
Why do gases have the highest rate of diffusion?
Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Graham’s Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
What is rate of diffusion of gas?
rate of diffusion=amount of gas passing through an areaunit of time. The diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel.
What is the diffusion of gases?
Gaseous atoms and molecules move freely and randomly through space. Diffusion is the process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration.
Which gas is most easily liquefied?
Solution : NH3 can be liquefied easily as its molecules can interact through intermolecular hydrogen bonding which is possible because an H atom is directly bonded to a highly electronegative N atom with a lone pair. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
Which gas will liquefy first?
ammonia
What is Liquefiable gas?
Liquefaction is useful when one gas is easily liquefiable. Liquefaction of gases is the process by which a gas is converted to a liquid by applying high pressure and low temperature. For example, oxygen normally occurs as a gas.
What gas is difficult liquefy?
Helium
