What factors affect the rate of diffusion? Some of the factors that affect the rate at which particles diffuse include: the particle's molecular weight, temperature, concentration difference, diffusion distance, permeability and surface area. Pressure is also known to affect the rate of diffusion since it increases the speed of molecules.

- Factors affecting diffusion are:    1) Temperature: The higher the temperature, the higher the rate of  diffusion.    Example: Put potassium permanganate in a b…eaker with water (room  temp.) and do the same in a beaker with water (boiled). The  potassium permanganate would spread faster in hot water.

What factors affect the rate of diffusion? The rate of diffusion is directly proportional to temperature; and The rate of diffusion is indirectly related to molecular weight (heavier particles move more slowly than lighter, smaller ones). At room temperature, the average velocity of a molecule is fast-about 2 km/sec (=3997 mph!).

- A: Particle size, temperature, concentration difference and diffusion distance affect the rate of diffusion. The particle size highly influences the rate of diffusion. Since the heat of the environment is the energy source for diffusion, a smaller particle at a given temperature moves faster than a larger particle.

The Effect of Molecular Weight on the Diffusion Rate of Substances1 2 ABSTRACT. The effect of molecular weight on the diffusion rate of substances was determined using the glass tube test and the agar-water gel test. In the glass tube test, two cotton plugs were soaked with hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were inserted into both ends of the glass tube. NH4OH.

Biology: Why do smaller cells have higher rate of diffusion? If the membrane is not permeable, the concentration makes no difference as nothing can move. Surface area to volume ratio is important because as the ratio decreases (becomes closer to a 1:1 ratio), then there is not enough surface to allow for diffusion to sservice the contents or volume of the cell.

- Cultural diffusion concerns the spread of culture and the factors that account for it, such as migration, communications, trade, and commerce. Because culture moves over space, the geography of culture is constantly changing.

Anatomy and Physiology of Animals/The Cell Diffusion depends on where the higher and lower concentrations of solutes are (molecules move from high to low concentration), what kind of membrane (if any) the molecules are … moving through, and in many cases how large and charged the molecules are.

Factors That Affect the Rate of Dissolving & Solubility (2) Transcript of Factors That Affect the Rate of Dissolving & Solubility (2) Polar and ionic bonds are most likely to dissolve in water. Polar covalent and covalent bonds most likely will not. In order to distinguish between a mainly ionic bond or mainly covalent bond, we find the electronegativity of a compound.

Where in the human body does diffusion occur? Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process.

The Effect of Molecular Weights on the Rate of Diffusion Thus, the higher the molecular weight, the slower the rate of diffusion. INTRODUCTION Diffusion is defined as the random spreading out of particles from regions of higher concentration to regions of lower concentration.

- Diffusion also plays a part in moving substances into and out of cells. For example, imagine an amoeba living in water. The concentration of dissolved carbon dioxide gas in the water is the same as the concentration of dissolved carbon dioxide gas in the amoeba's cytoplasm.iffusion The structure of the cell membrane controls what moves in or out of a cell. According to the particle model particles are moving in all directions, bumping into each other.Diffusion – movement of particles from an area of high concentration to and area of low concentration until the concentrations are equal.

What are the abiotic factors of the Savannah? How do they affect it? Abiotic factors: Climate. With climate comes precipitation and temperature. Seasonal changes and location of the savannah affects what will grow and when. Snowfall will kill off any warm-season plant that cannot go dormant and rest through the winter to await spring.

Biochemistry Diffusion is important in the transport (movement) of molecules into and out of the cell. Depending on the concentration gradient will be whether certain materials will either enter or leave cells by diffusion. The process of diffusion plays an important role in the enrty and exit of molecules in living cells.

- The difference in concentration is known as the concentration gradient. Diffusion is very important in the body for the movement of substances eg the movement of oxygen from the air into the blood and carbon dioxide out of the blood into the air in the lungs, or the movement of glucose from the blood to the cells.

4. Factors affecting photosynthesis. Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. Light intensity. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.ncreasing the light intensity will boost the speed of photosynthesis. Carbon dioxide concentration. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.

# 63 Transpiration in plants and factors affecting transpiration rate This creates a traspiration stream, pulling water up from the root. The rate of transpiration can be affected by several factors: The opening and closing of the stomata is controlled by the guard cells. In light, guard cells take up water by osmosis and become turgid. Because their inner walls are rigid they are pulled apart, opening the pore.

Calculating the Oxygen Diffusion Coefficient in Air The diffusion coefficient D is a function of both temperature and pressure. Diffusion increases with increasing temperature (as molecules move more rapidly), and decreases with increasing pressure (which packs more molecules in a given volume, making it harder for them to move).his discussion is part of a section on oxygen transport and oxygen diffusion in compost, which provides background on the general concepts and equations.
