What affects the rate of passive transport?
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.
What are the three primary factors that determine transportation rates?
The main factors in determining the freight rate are: mode of transportation, weight, size, distance, points of pickup and delivery, and the actual goods being shipped.
What are the 6 factors that can influence the rate of diffusion?
The rate of diffusion
| Factor | Reason |
|---|---|
| The temperature | The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. |
| The surface area of the cell membrane separating the different regions | The greater the surface area, the faster the rate of diffusion. |
What are the 3 factors that affect the rate of diffusion?
Factors that Affect the Rate of Diffusion
- Difference in concentration affects the rate of diffusion. The greater the concentration gradient, the quicker diffusion takes place. …
- The temperature affects the rate of diffusion. …
- The surface area of the membrane affects the rate of diffusion. …
- Distance.
What are the factors determining the transportation demand?
Many factors can affect travel demand, including demographics, the quality of facilities, the quality and price of alternatives, and land use patterns, as summarized in Table 1.
Why does the following affect the rate of diffusion?
Temperature: Higher temperatures increase the energy and therefore the molecules' movement, increasing the diffusion rate. Lower temperatures decrease the molecules' energy, thus decreasing the diffusion rate. Solvent density: As the density of a solvent increases, the diffusion rate decreases.
Does temperature affect the rate of diffusion?
When temperature increases, the kinetic energy of the particles has increased. The increased motion of the particles causes them to diffuse faster. Therefore, at higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.
What are the basis of transportation rates?
Land is the basic basis of transportation because of its extreme importance. It can provide door to door services; cost of land transportation is reasonable; less chance of the goods to get damaged ,etc.
Which factor does transportation cost mainly depend on?
Transportation cost mainly depends on distance, weight of merchandise and the time required for transportation.
What are the 5 factors that affect diffusion?

- Concentration gradient.
- Permeability of the membrane.
- Temperature.
- Pressure.

How does supply and demand affect transportation?
When the demand for transport increases against a constant supply, the cost of transportation is bound to go up, and this may serve to attract new players into the market. On the contrary, an increase in transport supply without a corresponding increase in demand for transport often leads to lower cost of transport.
Why is transport a delivery demand?
Transportation can also be perceived as an induced (or latent) demand, representing a demand response to a price reduction. This is particularly the case when the addition of transport infrastructures results in traffic increases due to higher levels of accessibility.
How does density affect the rate of diffusion?
Solvent density: As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.
How does pressure affect the rate of diffusion?
The higher the pressure, the denser is the molecule packing, the less is the free-path length, and the slower is the diffusion. The same occurs as molecule mass and size increase.
What are the factors to consider when choosing mode of transport?

- Nature of Commodity: …
- Other Considerations:
What have been the main factor affecting freight rates in recent years?
Market forces are the main driving factor behind the freight rate fluctuations. Factors such as fuel prices, distance traveled, terminal costs, etc. don't impact freight rates as much as supply and demand do.
What do you understand by transportation rates?
Rates are the price of transportation services paid by their users. They are the negotiated monetary cost of moving a passenger or a unit of freight between a specific origin and destination. Rates are often visible to the consumers since transport service providers must provide this information to secure transactions.
Does pressure affect rate of diffusion?
Diffusion coefficients are inversely proportional to total pressure or total molar density and are therefore reported by convention at a standard pressure of one atmosphere. Doubling the pressure of a diffusing mixture halves the diffusion coefficient, but the actual rate of diffusion remains unchanged.
What are 5 factors that affect the rate of diffusion of a substance?
Factors affecting the rate of diffusion are as follows: Concentration gradient Permeability of the membrane Temperature Pressure
- Concentration gradient.
- Permeability of the membrane.
- Temperature.
- Pressure.

What are the two major factors affecting supply and demand of road transport services?
For road and rail, transport supply is often dependent on the capacity of the routes and vehicles (modal supply), while air and maritime transportation transport supply is strongly influenced by the capacity of the terminals (intermodal supply).
What are the determinants of demand for transport?
The results revealed that travel time and travel cost are among the most influential factors for forecasting the demand of public transport. Other socio-demographic factors such as gender, age, monthly income, and vehicle ownership are also demand determinant factors.
What are the needs for transportation?
The Need for Transportation Transportation is needed because few economic resources—raw materials, fuels, food, manufactured goods—are located where they are wanted. Each region or place on Earth produces more than it consumes of some goods and services and less than it consumes of others.
Does mass and density affect diffusion?
Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.
Which is the most important factor in choosing the correct mode of transport?
The volume or weight of the goods play a key role in determining which method of transport is the best value. Also the type of good in terms of urgency of delivery, such as how perishable the goods are, and how quickly they need to arrive, influences the choice of mode of transport.
What are the factors affecting transport Class 12?
Factors Affecting Transport Routes depend on: location of cities, towns, villages, industrial centres and raw materials, pattern of trade between them, nature of the landscape between them, type of climate, and funds available for overcoming obstacles along the length of the route.
How are shipping rates determined?
The four elements required to calculate shipping costs are shipping point and origin, package weight, package dimensions and expected delivery times. You can calculate the majority of postal shipping rates using these figures. With this information, you can compare shipping rates using a shipping cost calculator.
