Which of these actions a sustainable practice?
tia_tia [17]
<h2>Hello!</h2>

A sustainable practice is B. Setting usage limits on a resource

<h2>Why? </h2>

Sustainable practices are those that aim to reach an equilibrium between the use of natural resources for human development, and the preservation of the environment for future generations.

Setting usage limits on a resource is a sustainable practice because it allows for taking advantage of the resource, while providing constraints to its use, forcing the industry to be creative and develop alternative methods that take better advantage of that resource, or that use different resources (e.g. limiting fossil fuel emissions, forcing the industry to find alternative ways to generate power like solar energy).

Have a nice day!

An ideal gas described by Ti=291K, Pi=1.50bar, and Vi=13.3L is heated at constant volume until P=15.0bar. It then undergoes a re
Salsk061 [2.6K]

Answer:

W=-4601.4J

Explanation:

Hello,

In this case, the steps are:

291K,1.50bar, 13.3L \rightarrow 15.0bar 13.3L,T_2\rightarrow T_2, V_2, 1.50bar\rightarrow 291K,1.50bar, 13.3L

In such a way, the work per mole (w) for that isothermal process turns out:

w=RTln(\frac{P_1}{P_2} )=8.314\frac{J}{mol*K}*291K*\frac{1.50bar}{15.0bar} \\\\w=-5570.8\frac{J}{mol}

In addition, if the moles are required, since it is an ideal gas:

n=\frac{PV}{RT}=\frac{1.50bar*13.3L}{0.083\frac{bar*L}{mol*K}*291K} =0.826mol

So the work is:

W=-5570.8\frac{J}{mol} *0.826mol=-4601.4J

Best regards.
