Answer:
Q = 62 ( since we are instructed not to include the units in the answer)
Explanation:
Given that:
![n_{HCl} = 3 \ kmol\\n_{Ar} = 7 \ k mol](https://tex.z-dn.net/?f=n_%7BHCl%7D%20%3D%203%20%5C%20kmol%5C%5Cn_%7BAr%7D%20%3D%207%20%5C%20k%20mol)
![T_1 = 27^0 \ C = ( 27+273)K = 300 K](https://tex.z-dn.net/?f=T_1%20%3D%2027%5E0%20%5C%20C%20%3D%20%28%2027%2B273%29K%20%3D%20%20300%20K)
![P_1 = 200 \ kPa](https://tex.z-dn.net/?f=P_1%20%3D%20200%20%5C%20kPa)
Q = ???
Now the gas expands at constant pressure until its volume doubles
i.e if ![V_1 = x\\V_2 = 2V_1](https://tex.z-dn.net/?f=V_1%20%3D%20x%5C%5CV_2%20%3D%202V_1)
Using Charles Law; since pressure is constant
![V \alpha T](https://tex.z-dn.net/?f=V%20%5Calpha%20T)
![\frac{V_2}{V_1} =\frac{T_2}{T_1}](https://tex.z-dn.net/?f=%5Cfrac%7BV_2%7D%7BV_1%7D%20%20%3D%5Cfrac%7BT_2%7D%7BT_1%7D)
![\frac{2V_1}{V_1} =\frac{T_2}{300}](https://tex.z-dn.net/?f=%5Cfrac%7B2V_1%7D%7BV_1%7D%20%20%3D%5Cfrac%7BT_2%7D%7B300%7D)
![T_2 = 300*2\\T_2 = 600](https://tex.z-dn.net/?f=T_2%20%3D%20300%2A2%5C%5CT_2%20%3D%20600)
mass of He =number of moles of He × molecular weight of He
mass of He = 3 kg × 4
mass of He = 12 kg
mass of Ar =number of moles of Ar × molecular weight of Ar
mass of He = 7 kg × 40
mass of He = 280 kg
Now; the amount of Heat Q transferred = ![m_{He}Cp_{He} \delta T + m_{Ar}Cp_{Ar} \delta T](https://tex.z-dn.net/?f=m_%7BHe%7DCp_%7BHe%7D%20%5Cdelta%20T%20%20%2B%20m_%7BAr%7DCp_%7BAr%7D%20%5Cdelta%20T)
From gas table
![Cp_{He} = 5.9 \ kJ/Kg/K\\Cp_{Ar} = 0.5203 \ kJ/Kg/K](https://tex.z-dn.net/?f=Cp_%7BHe%7D%20%3D%205.9%20%5C%20kJ%2FKg%2FK%5C%5CCp_%7BAr%7D%20%20%3D%200.5203%20%5C%20%20kJ%2FKg%2FK)
∴ Q = ![12*5.19*10^3(600-300)+280*0.5203*10^3(600-300)](https://tex.z-dn.net/?f=12%2A5.19%2A10%5E3%28600-300%29%2B280%2A0.5203%2A10%5E3%28600-300%29)
Q = ![62.389 *10^6](https://tex.z-dn.net/?f=62.389%20%2A10%5E6)
Q = 62 MJ
Q = 62 ( since we are instructed not to include the units in the answer)
