Increase!!!!77
As an example. Take a block of butter. 'Butter' because it weill cut easily.
As sold, it will have six faces of say 2 x 3 x 6 =
So surface area is
2[(2 x 3) + (3x6) +( 2 x 6)] = 2[6 + 18 + 12] = 72 unuts^2
Now cut the block into two equal sized blocks . Each block will have 2 x 3 x 3 dimensions.
2[(2 x 3) + (3x3) +( 2 x 3 )] = 2[6 + 9 + 9] = 48 unuts^2
However there are two blocks so 48 ubits^2 + 48 units^2 = 96 units^2
Hence
One block : 2 blocks :: 72 units^32 : 96 units^2
So surface area has increased.

When you crush a solid do you increase or decrease surface area?
You increase the surface area
Does crushing a solute increase or decrease its total surface area?
Increase...by alot.
Do cells divide to have a smaller surface area?
No. In fact, if they retain their combined volume, their surface area would increase.
Why do smaller cells have a greater surface area to volume ratio?
If the cells are spherical, the surface area increases as the square of the radius while the volume increases as the cube of the radius. Therefore, as the cells become larger, their volumes increase much more rapidly than their surface areas. Conversely, as the cells become smaller, their volumes decrease much more rapidly that their areas and so the surface area to volume increase. With non-spherical cells the calculations are much more complex, but the general pattern still applies.
What is the tendency of liquids to decreases their surface area to the smallest size possible?
The surface area of the liquid can decrease when there is increase in the temperature of the day,what is called evaporation is been taking place in the surface of the liquid,wchich decreases the liquid area.
Why does a solid solute dissolve quicker if it is crushed into smaller particles?
YES by crushing it into smaller particles we increase the surface area thereby increasing its contact with the solution
Does the surface energy increase or decrease with increase in planar density?
decrease
When you crush a solid do you increase or decrease surface area?
You increase the surface area
What is surface area and how you can decrease or increase surface area?
You can increase surface area by spreading the object
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 crushing a solute increase or decrease its total surface area?
Increase...by alot.
Does the air increase or decrease towards the surface with a high pressure?
Air density and pressure increase nearer the surface
Are smaller particles weathered more rapidly than larger particles?
Yes, because smaller particles are more exposed to air (large surface area).
Does density of water increase or decrease the surface tension of water?
tenson #
If ozone layer is destroyed on earth surfaces earth surface temperature decrease or increase?
it will increase (get hotter).
Does pressure and temperature increase or decrease with depth below earths surface?
it increases
Why does physisorption decrease with the increase of temperature?
there are vanderwaals forces between the moleculs and a solid surface.
