saul85 [17]
A micelle refers to an aggregate of a surfactant molecule, which a dispersed in a liquied colloid. In an aqueous liquid, a micelle is arranged in such a way that its hydrophillic head region will be in contact with the surrounding solvents while the hydrophobic tail region will be embedded in its center. 
The three dimensional shape of a micelle is A SPHERE.

A balloon is filled with helium gas has a volume of 1.0 L at a pressure of 1.0 atm. The
stiv31 [10]

Answer:

<h2>2.5 L</h2>

Explanation:

The new volume of the balloon can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{1 \times 1}{0.4}  =  \frac{1}{0.4}  \\  = 2.5

We have the final answer as

<h3>2.5 L</h3>

Hope this helps you
