Why do skis have a larger surface area?
The larger the surface area the more pressure can be spread out, therefore it is less likely to fall through the snow. As pressure = f / a.
Describe what happens to the surface area to volume ratio for larger and larger cubes?
For a cube with edge length, L. Surface area = 6L2. Volume = L3. So ratio of Surface Area / Volume = 6 / L. Therefore, as the side length, L, increases, the ratio will decrease.
Does the diameter surface area and circumference affect the heat loss?
yes heat loss is affected by diameter, circumference and surface area. Heat loss depends on the surface area : volume ratio.......the larger this is the more heat is lost if a cylinder having the same volume but a different surface area...(therefre radius and circumference is different)........the cylinder having the larger surface area will loose heat fastest
What happens to the surface area of a cube when it doubles?
I will rephrase your question: What happens to the surface area of a cube when the volume doubles. Ans. Surface area becomes 1.5876 times larger. Explanation: Let L = the length of the side of the original cube and h x L the length of the cube that is double the volume. Now: Vol= L^3 x 2 = (h x L)^3 or h = 2^(1/3) = 1.2599, so the length will be 1.2599 times larger. Surface area = 6 x L^2 for original cube and 6 x L^2 x 1.2599^2 for the cube with twice the volume. 1.2599^2 = 1.5876 If you are asking what happens to the surface area when the sides double, then the larger cube has surface area = 6 * 2^2 * L^2 , so 6 * 2^2 = 24. Each side is 4 times larger so the total surface area is 24 times larger.
The total area for gas exchange in the lung is about 10 square meters larger than the entire surface of the body?
FALSE!
A larger surface area makes diffusion happen more quickly?
Yes, a larger surface area allows for more contact between the molecules involved in diffusion and the surrounding environment, facilitating a faster exchange of molecules. This is because more molecules can be in contact with the surface at the same time, increasing the rate of diffusion.
What are 5 factors that affect diffusion?
Concentration gradient: The greater the difference in concentration between two areas, the faster diffusion occurs. Temperature: Higher temperatures generally increase the kinetic energy of particles, leading to faster diffusion. Molecular size: Smaller molecules diffuse more quickly than larger ones, as they can move more easily through spaces. Medium through which diffusion occurs: Diffusion occurs more readily in gases and liquids compared to solids. Surface area: The larger the surface area available for diffusion, the faster the rate of diffusion.
How does surface area affect diffusion rate?
Surface area directly affects the rate of diffusion by providing more area for molecules to interact; a larger surface area leads to faster diffusion rates because there are more opportunities for molecules to move across the membrane. With a greater surface area, more molecules can pass through the cell membrane at the same time, increasing the overall rate of diffusion.
What are the three things that affect diffusion?
Three main factors that affect diffusion are temperature (higher temperature increases rate of diffusion), concentration gradient (greater difference in concentration leads to faster diffusion), and surface area (larger surface area allows for more diffusion to occur).
What factors affect simple diffusion?
Factors that affect simple diffusion include concentration gradient (higher concentration difference leads to faster diffusion), temperature (higher temperatures increase diffusion rate), surface area available for diffusion (larger surface area allows for faster diffusion), and characteristics of the molecules themselves (size and solubility).
Which cell has the fastest rate of diffusion across the surface?
Cells with a larger surface area-to-volume ratio, such as small cells like bacteria or single-celled organisms, will typically have a faster rate of diffusion across the surface. This is because a larger surface area allows for more space for molecules to diffuse in and out of the cell more efficiently.
What is the effect of size of uptake on diffusion in agar?
larger the size, the smaller the surface area to volume ratio, hence the slower the rate of diffusion into the agar jelly :)
What are some factors that might aid or slow diffusion?
Factors that can aid diffusion include high temperature, smaller molecular size, steep concentration gradients, and a larger surface area for exchange. Factors that can slow diffusion include low temperature, larger molecular size, long diffusion distances, and obstacles in the medium through which diffusion is occurring.
The rate of diffusion depends on?
The rate of diffusion depends on the concentration gradient, temperature, molecular weight, and surface area available for diffusion. A steeper concentration gradient, higher temperature, smaller molecular weight, and larger surface area all contribute to faster rates of diffusion.
What factors most affect the rate of diffusion?
The factors that most affect the rate of diffusion include the concentration gradient (difference in concentration between two areas), temperature (higher temperatures increase molecular motion), surface area (larger surface area allows for more contact between molecules), and the size and nature of the particles diffusing (smaller, nonpolar molecules diffuse more quickly).
Why small particle has more surface area than larger particle?
That depends upon the shape of the particles. * If they are spherical, the surface area is 4*pi*r^2, where r is the radius of the particle. * If they are cuboidal, the surface area is b*w*h, where b, w, h are the lengths of the sides
What controls the rate of diffusion?
The rate of diffusion is controlled by factors such as concentration gradient, surface area available for diffusion, temperature, and the size of the molecules involved. A steeper concentration gradient, larger surface area, higher temperature, and smaller molecules generally lead to faster diffusion rates.
