A surface is where things happen between what is on one side of the surface and the other. Thus in general if you want more of these happenings (eg gas exchange) you need the biggest possible surface area. If however you want to minimise these happenings (eg heat loss) you try and reduce the surface area.
The function of air sacs (alveoli) is to provide a large surface area for gas exchange
The bunsen burner is used to heat items for experiments using a controllable temperature flame and surface area at which the heat is applied to the vessel.
Yes. There are ways to do that, but it depends on what you wish to change the surface area of. Changing the surface area of something like, say, a shotput is difficult, but changing the surface area of a balloon can be accomplished by merely blowing it up (more) or deflating it.
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
To increase the surface area for gaseous exchange.
All villi increase surface area.
The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.
Area = 6s2 where s is the length of an edge.
increase surface area over which air pass through
The expense to paint the shed is a function of the shed's surface area.
The expense to paint the shed is a function of the shed's surface area.
A(5) = 4 25
The shape of the plant cell relates to its function directly. For instance, the epithelium has a large surface area due to its function of absorption.
Haemoglobin it has a large surface area
the villi vastly increases the surface area for the absoption of food.
To increase the surface area-to-volume ratio of a basketball, you can deflate it slightly, which will cause it to have more wrinkles and bumps on its surface. For a tennis ball, you can cut it into smaller pieces, such as quarters, which will increase the surface area relative to its volume.
