Answer:
Colloidal dispersion or emulsion
Explanation:
The colloid of a liquid in liquid (both dispersed phase and dispersion medium are liquids) is known as emulsion or colloidal dispersion.
We know that oil and water are immiscible liquids. In order to make them miscible we have have add emulsifying agents.
An emulsifying agent has a long non polar hydrocarbon chain (in general) and a polar head.
For example salts of fatty acids.
The polar head is hydrophilic and non polar tail is hydrophobic.
It causes the miscibility of the two polar and non polar liquids
means 0.5 raise to the power of n. "To the power of" means an action of multiplication of 0.5 to n times.
The different values of n are given in the table. Substituting these values:
For A:
n = 1 (given)
For B:
n = 2 (given)
For C:
n = 3 (given)
For D:
n = 6 (given)
For E:
n = 8 (given)
Hence, the values are:
A = 0.5
B = 0.25
C = 0.125
D = 0.015625
E = 0.00390625
The temperature that the balloon will expand to 3.50 l is 463.56 K
<em><u> calculation</u></em>
by use of Charles law formula
that is V1/T1 = V2/T2 where;
V1 = 2.25 l
T1= 298 k
V2= 3.50 l
T2=?
make T2 the subject of the formula T2 =(V2 xT1) /v1
T2= (3.50 l x 298 K) /2.25 L = 463.56 K
