Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
What are the characteristics of respiratory surface?
large area
What organelle has a large amount of surface area?
The Alveoli
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
How the surface area affects heat loss?
Heat loss of water: The surface area effects the the rate of heat loss because the rate of heat loss increases if the surface are is higher. How: The water is spread out into a bigger space meaning the
Why do roots spread out and get thinner?
they spread out and cover a large surface area which helps the roots take in water from the soil more quickly.
How do the large feet of a polar bear act to reduce the pressure on ice?
it will spread it out across the large surface area therefore decreasing it. hope that helps! :)
What effects the rate of a chemical reaction?
Temperature, pressure, catalyst, surface area
Why does catalyst burn sugar?
Sugar is small crystal powder, thus each sugar crystal has large surface area which causes rapid reaction in presence of catalyst. This reaction produces a lot of heat, as a whole, that it causes sugar to burn.
Why you use the porcelain chips as the catalyst for the dehydration of ethanol?
Porcelain chips are used as a catalyst for the dehydration of ethanol because the rough surface of the chips provides a large surface area for the reaction to occur, allowing for more contact between the reactants and catalyst. This helps to enhance the rate of the dehydration reaction and improve the overall efficiency of the process.
Why does a catalytic converter have a honeycomb structure?
Because honeycomb structure provide large surface area to the exhaust gasses for reaction under the action of catalyst then any other structure.
What is the area of 5 gallons of water?
Surface area? That will vary considerably. The smallest surface area will be if the water is suspended weightless, in the shape of a sphere. It could be in a pan 1/16 of an inch deep. Specify the shape you are interested in.
Why doesn't it hurt so much if you sit on a seat made of lots of pins?
your weight is spread on a large surface area so the pressure will not be as large as if you sat on one pin.

Why is a catalyst more effective in powdered form?
Higher surface area is available for the chemical reaction.
Why is gauze known as a catalyst?
Gauze is often used as a catalyst support in chemical reactions because it provides a large surface area and helps distribute reactants evenly. The porous nature of gauze also allows for good gas flow, aiding in the efficiency of the reaction.
What can a bet surface area be used for?
The BET surface area can be used in catalyst manufacturing for the determination of adsorption of of gas (isotherm), pore volume, distribution of pore size.
