What can increase or decrease the rate of diffusion?
Factors that can increase the rate of diffusion include increasing the concentration gradient, increasing temperature, decreasing the distance for diffusion, increasing surface area, and reducing the size of the molecules diffusing. Factors that can decrease the rate of diffusion include decreasing the concentration gradient, decreasing temperature, increasing the distance for diffusion, decreasing surface area, and increasing the size of the molecules diffusing.
Will increasing the surface area of a reactant decrease the rate of a chemical reaction?
No, increasing the surface area of a reactant will not decrease the rate of a chemical reaction; in fact, it typically increases the reaction rate. A larger surface area allows for more collisions between reactant particles, facilitating more frequent interactions that can lead to a reaction. This is why powdered solids often react faster than larger chunks of the same material.
As the altitude increases does the barometric pressure increase or decrease?
As altitude increases, barometric pressure decreases. This is because the air pressure decreases with increasing altitude, as there are fewer air molecules in the atmosphere exerting pressure on a given area.
What increases the surface area of the cerebral?
The surface area of the cerebral cortex is increased by its folding into gyri and sulci. This folding allows for more neurons to be packed into a smaller space, increasing the brain's processing power without significantly increasing its size.
Does increasing the surface area increase or decrease the rate of a chemical reaction?
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
Does increasing the surface area of a solid decrease the rate of solution?
no

How do you find the perimeter of a triangle if you know the area?
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.

How is force pressure and area related?
Force, pressure, and area are related through the equation pressure = force / area. This means that pressure is directly proportional to force and inversely proportional to area. Increasing force applied on a given area will increase the pressure, while increasing the area over which the force is applied will decrease the pressure.
What are two methods for increasing the dissolving rates of gases in liquids?
increasing the area of contact between the gas and liquid (without shaking it) decreasing the temperature of the system
As the altitude increases does the barometric pressure increase or decrease?
As altitude increases, barometric pressure decreases. This is because the air pressure decreases with increasing altitude, as there are fewer air molecules in the atmosphere exerting pressure on a given area.

What will be the impact on the pressure if area is doubled?
If the area is doubled while the force remains constant, the pressure will be halved. This is because pressure is inversely proportional to area according to the formula P = F/A, where P is pressure, F is force, and A is area. Thus, increasing the area will decrease the pressure.
Does increasing the surface area increase or decrease the rate of a chemical reaction?
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
What happens if the surface area of the respiratory membrane decrease in gas exchange?
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
What are the two factors of a wire that will alter its resistance?
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
