Natalka [10]

Answer:

the value of change in entropy for freezing process of 1 mole of liquid methanol is -18.07 J/mol.k

Explanation:

Entropy is defined as the measure of possible arrangement of the atoms or molecules. Entropy change for the the freezing process mole of 1 liquid methanol at -97.6 degree celcius and 1 atm will be -18.07 J/mol.

The entropy change can be calculated by the given formula:

 

Thus, the value of change in entropy for freezing process of 1 mole of liquid methanol is -18.07 J/mol.k

Given the function f(x) = 3(x – 2)2 + 4 with a restricted domain of x ≥ 2, which of the following represents f–1(x)?.
Debora [2.8K]

The inverse of the function is f^{-1}x= \sqrt{\frac{x-4}{3} } + 2

<h3 /><h3>Domain and Range of functions</h3>

Given the function

f(x) = 3(x - 2)^2 + 4

To get the inverse, you will follow the same step as shown:

Rewrite the equation to have:

y= 3(x - 2)^2 + 4

Replace x with y

x = 3(y - 2)^2 + 4

<h3>Make y the subject of the formula</h3>

x = 3(y - 2)^2 + 4\\x-4=3(y - 2)^2\\\frac{x-4}{3} = (y-2)^2\\ y-2=\sqrt{\frac{x-4}{3} } \\y = \sqrt{\frac{x-4}{3} } + 2

Hence the inverse of the function is f^{-1}x= \sqrt{\frac{x-4}{3} } + 2

What does the evolution in how we understand the identities of superman suggest about how society's view of identity changed ove
wlad13 [49]

There has been several evolution overtime. The one that tells  how we understand the identities of Superman suggests that society's view of identity is known to be subjective.

  • Here, the society takes identity at face value instead of the use of other form of evidence.

<h3>Why a subjective view?</h3>

From the study of the Superman's secret identity and its evolution, it therefore shows how the society really see the idea about identity.

Note that Clark Kent in the story has the same resemblance to Superman but they are of two identities types.

People often can see and accept one of the identity type they conform to them and ignore any kind of anomaly such as that of superman.  So we can say that they are two different persons living two different lives.
