When building a campfire why is it easier to set fire to a piece of paper than to a branch or twig?
The fibers in paper have more exposed surface area than the fibers in wood. (NovaNet)
How does surface area effect heat loss?
the larger the surface area you have, to more heat that you are going to lose.
Which has more surface area a rectangular prisms or rectangular pyramid?
For the same base dimensions (base area) and the same height, the rectangular prism has more surface area.
Is larger surface area break on a cycle wheel more effective than smaller surface area breaks?
Yes.
Does a cylinder or rectangle have more surface area?
rectangle
Why does a crumbled piece of paper have less air resistance?
When you crumple a paper you are decreasing the surface area. The less surface area, the less the wind can stop the paper. it also works because you are putting more weight on one area.
Why does a flat piece of paper fall slower than a crumbled piece of paper?
A flat piece of paper has a larger surface area, creating friction with the air, or more air resistance. There is more air surrounding the piece of paper, and this slows it down. A crumpled piece of paper has less surface area to create friction, meaning less air resistance. This causes it to fall faster.
Why would a crumpled piece of paper hit the ground before a flat piece of paper?
Because a flat piece of paper has a larger surface area and therefore more wind resistance. But in a crumbled piece of paper the wind resistance is less.
How much faster does a crumpled paper fall than a flat sheet show a video?
Because there is less surface area on the crumbled piece of paper, there is less area upon which the force of friction (air resistance) may act. There is more surface area on the normal piece of paper, which allows friction to act over a greater area on the paper. More air resistance causes the flat piece to fall slower.
A student has two identical sheets of paper He crumples one into a small ball and drops the sheet of paper and the ball of paper off a building at the same time which will reach the ground first?
If we are talking in vaccum then both will have same acceleration.But if there is no vaccum then paper crumbled into a ball will have greater acceleration because air resistance will be less for it.
Will the crumbled paper folded paper or unfolded paper fall first?
The crumbled. It's more like a ball, unlike the 2D paper. And since you can't keep the paper completely folded, It might as well be in 2nd place.
Why does the crumpled paper fall faster the ground than the uncrumpled paper?
The flat paper has more surface area, allowing it to catch more air and float. The crumpled paper on the other hand, does not, because it doesn't have as much surface area to spread the air out.
Do two pieces of paper one crumpled the other not fall at the same rate and explain?
They do not. Since a crumbled and an uncrumbled paper has the same weight but not the same surface area they will have the same gravitational pull but the difference in surface area give them diffent air resistance. Air resistance is the force when the paper have to move the air molecules while falling. Since the unfolded paper have to move more molecules because of its bigger surface, it will move slower through the air since the papers have the same gravital pull and therefore the same amount of force moving them downward.
How does surface area affect diffusion rate?
Diffusion is the movement of particles across a selectively permeable membrane, from a high concentration to a low concentration. So the larger the surface area, the quicker the rate of diffusion because there is more space to diffuse in.
Will a flat piece of paper dropped from a height of two meters accelerate at the same rate As a piece of paper crumbled into a ball why or why mot?
In a vacuum, yes, look up the video on youtube of dropping a feather and hammer on the moon. However, on earth, that is not the case, due to air resistance. The flat paper has more surface area for the air to push back up on, and therefore slows it down more
If you drop a pape and a bouncy ball which will fall first?
the sheet of paper,because it has more surface area
Would cardstock notebook paper construction paper or butcher paper burn the quickest?
Generally, the fuel with the higher surface-to-mass ratio would be more volatile, since surface area contributes to pyrolysis and combustion.
