Answer:

$W = 3542.7 J$

Explanation:

As per ideal gas law we know that

PV = nRT

so we have

$P = 1.01 \times 10^5 Pa$

$n = \frac{92}{28} = 3.28 moles$

T = 200 K

now we have

$(1.01 \times 10^5) V = 3.28 (8.31)(200)$

$V_1 = 0.054 m^3$

Now we know that if pressure remains constant

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

$\frac{0.054}{200} = \frac{V_2}{70}$

$V_2 = 0.0189 m^3$

Now work done in this process is given as

$W = P \Delta V$

$W = (1.01 \times 10^5)(0.054 - 0.0189)$

$W = 3542.7 J$

kirill [66]

The variables that Madison will have to deal with to test her hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals are as follows:

Independent variable: concentration of salt
Dependent variable: corrosion of metal

<h3>What are independent and dependent variables?</h3>

In an experiment, the independent variable is the variable that is changed or manipulated in a series of experiments.

On the other hand, a dependent variable is that outcome measured to see the effectiveness of the treatment.

According to this question, Madison makes an hypothesis that an increased concentrations of salt in the air speeds the corrosion of certain metals, the variables she should look out for are as follows:

Independent variable: concentration of salt
Dependent variable: corrosion of metal
