Homework Statement
Suppose a lipid droplet is essentially a sphere with a diameter of 1 cm.
For A – D below, the area of a sphere is 4π r2, and volume is 4/3πr3.
For π, use a value of 3.14.
Show your calculations neatly in the space provided to receive credit for your answer.
Round all answers to the nearest tenth.B. Now, suppose that this sphere were emulsified into 100 essentially equal-sized droplets. What is the average surface area to volume ratio of each droplet?C. How much greater is the total surface area of these 100 droplets compared to the original single droplet?
D. How much did the total volume change as a result of emulsification?
Homework Equations
Surface Area / Volume
The Attempt at a Solution
What is the surface area to volume ratio of the droplet?
Answer: 6.0
Surface Area / Volume = 4 x (3.14) x .5^2 / (4/3) x 3.14 x .5^3 = 6.04 or 6.0I figured out A but am stuck on part B through D. Can you help? Thank you! Thank you!
I don't know how the equation evolves when the sphere is emulsified into 100 equal droplets. I know that the surface area
must increase but I cannot get it to work :(
