How does the surface area of an egg affect its boiling time?

Answer 1

Probably the larger the surface area the longer it takes to boil.

Answer 2

Assuming that the egg is almost spherical. The volume to surface area ratio will increase with increasing size of the egg. So it will take longer to cook a bigger egg. For a sphere:

V/A = R/3 where V= volume, A = surface area and R is the radius

Answer 3

Greater surface area would mean that the egg would cook faster because there is more area to absorb the heat. Normally though, to increase the surface area you would also increase volume and this means that it would absorbe more heat and take longer to cook. So in a normal egg, it would take longer to cook.

If you could develop an egg where you could increase te surface area without increasing the volume of the egg it would cook faster.

Answer 4

Lets just say it's a spherical egg. The boiling time would be proportional to the volume which is proportional to the cube of the radius. The surface area is proportional to the square of the radius.

S~12.6R^2
V~4.2R^3

so... V~1.2S^(3/2)

The volume is proportional to the cube of the square root of the surface area.

Answer 5

the important parameter is actually surface to volume ratio, and total egg volume

if the surface is bigger but the volume is also bigger (a bigger egg), then the time for the whole egg to cook is going to be longer

however, if you have two eggs, each with the same total volume, but one has more surface, then it will cook faster

in order for two eggs of the same volume to have different surface areas they have to have different shape, for instance one could be slightly "skinnier and taller" than the other.

since egg shapes don't differ very much, in reality this effect is probably small

so, generally a bigger surface means a bigger volume and a lower surface to volume ratio and a slower cooking egg

Answer 6

you have responded your individual question right here. in case you boil the water first, then upload one egg, convey lower back to boil and boil for a extra 2 minutes - the egg would be cooked. or... you boil the water first (comparable volume) upload 6 x eggs, convey lower back to boil and boil for extra 2 minutes, its in fact a similar. the two plenty have been in boiling water for 2 minutes. the 2d (greater team) of eggs will take longer to come again lower back to the boil however the version could be minimum as a results of indisputable fact that in the time of the two situations, the eggs would be cooked.

Answer 7

the surface area of any object controls the rate at which energy can be transferred from one material to another. that is why computer heatsinks have many slits with wide sides. they're trying to maximize surface area. the more surface area, the faster the heat transfer.
