As partial pressure increases what happens to the rate of diffusion?
As the partial pressure increases, the rate of diffusion also increases. This is because there is a greater concentration gradient driving the movement of molecules from high to low pressure areas, leading to faster diffusion.
What happens to rate of diffusion on heating?
The rate of diffusion typically increases with increasing temperature because higher temperatures increase the kinetic energy of particles, causing them to move more rapidly. This increased movement allows particles to spread out and mix more quickly, leading to a faster rate of diffusion.
How a change in medium water to gelatin would affect the rate of diffusion?
A change in medium water to Gelatin would affect the rate of diffusion dramatically. The change from water to gelatin would slow down the rate of diffusion.
What factors most affect the rate of diffusion in a liquid or agas?
Two factors which determine the rate of diffusion of a liquid in another liquid include temperature and particle size. The higher the temperature, the faster diffusion takes place, and the smaller the particle, the faster diffusion takes place.
Why rate of diffusion in liquid is slower than in gases?
The rate of diffusion in liquids is slower than in gases because the particles in liquids are closer together and have stronger intermolecular forces, which hinders their movement compared to gas particles. This results in a slower diffusion rate in liquids.
What does NOT influence the rate of diffusion of a chemical across a plasma membrane?
Besides the concentration of the chemical, the pore size of the plasma membrane, and the osmotic pressure of the cytoplasm - nothing else influences the rate of diffusion of a chemical across a plasma membrane.
What is the effect of the density of liquid on the rate of diffusion?
The increase in density will decrease the rate of diffusion. There is an inverse relation between density and rate of diffusion.
What is diffusion rate proportional to?
rate of diffusion depends on the concentration gradient, surface area, distance over which diffusion takes place, size and nature of the diffusing molecule.
How do temperature effect the rate of diffusion?
higher temp = higher rate of diffusion
What condition does diffusion lead in the absence of other influences?
equilibrium
Does hydrogen gas have a low rate of diffusion?
No, it is the lightest gas of the universe so has the highest rate of diffusion.
What influences diffusion of ions across the membrane?
distance involved =diffusion at short distances occurs at a greater rate than diffusion at long distances area involved= diffusion over short distance occurs at a greater rate than diffusion over long distances Barriers=thicker barriers slow down rates of diffusion
What is the relationship between surface area to volume ratio and the rate of diffusion?
The higher the ratio, the faster the rate of diffusion
Does a temperature increase increase the rate of diffusion?
yes the higher the temprature the quicker the rate of diffusion
Does a larger distance does it speed up the rate of diffusion?
No, increasing the distance between particles does not speed up the rate of diffusion. In fact, diffusion rate is influenced by factors such as concentration gradient, temperature, and particle size but not necessarily distance alone. The rate of diffusion is generally slower over larger distances.
How does surface area to volume ratio of a cell affect rate of diffusion?
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
As partial pressure increases what happens to the rate of diffusion?
As the partial pressure increases, the rate of diffusion also increases. This is because there is a greater concentration gradient driving the movement of molecules from high to low pressure areas, leading to faster diffusion.
