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.

How is the number of neutrons and in nucleus of an atom calculated
Sav [38]
The number of neutrons in an atoms nucleus can be calculated by subtracting the atomic number of that atom from its mass number.

(mass number  -  atomic number = number of neutrons)
