Answer:
Work = - 4175.23 J
Heat Transfer = -4175.23 J
Explanation:
The work done in an isothermal process, is given by the following formula:
W = RT ln (P1/P2)
where,
W = Work done
R = Universal Gas Constant = 8.314 J/mol.k
T = Constant Temperature = 300 K
P1 = initial pressure = 150 KPa
P2 = final pressure = 800 KPa
using these values, we get:
W = (8.314 J/mol.K)(300 k) ln (150/800)
<u>W = - 4175.23 J</u>
Here, negative sign shows that work is done on the system.
In isothermal process, from 1st law of thermodynamics:
Heat Transfer = Q = W (Since change in internal energy is zero for isothermal processes)
<u>W = - 4175.23 J</u>
Here, negative sign shows that heat is transferred from the system to surrounding.
