Example;
Let's suppose an example of a thermodynamic system to explain the working of the calculatorology thermodynamics calculator.
Type of Process: Isothermal Expansion
Pressure (P): 2 atm
Temperature (T): 300 K
Volume (V): 5 L
Solution
Step 01: Calculate the Work Done
W = nRTln VfVi
- n = number of moles of the gas (assuming 1)
- R = ideal gas constant = 8.314 l/(mol.K)
- T = temperature
- Vf= final volume
- Vi= initial volume
For an isothermal process, the change in internal energy for an ideal gas is zero.
U = 0
In an isothermal process, the heat added to the system equals the work done by the gas.
Q = W
Let's calculate the work done for an isothermal expansion with an initial volume of 2 L and a final volume of 5 L:
Step 02: Inputting the values:
W = nRTln VfVi
W = 1 x 8.314 x 300 x ln VfVi
W = 1 x 8.314 x 300 x ln 52
Step 03: Compute the logarithm:
ln 52 ln(2.5) 0.916
Now calculate the work:
W = 8.314 x 300 x 0.916 2276.6 J
For an isothermal process with an ideal gas:
U = 0
Heat Added (Q):
Q = W = 2276.6J
Results
Work Done (W): 2276.6 J
Change in Internal Energy (ΔU): 0 J
Heat Added (Q): 2276.6 J
During the isothermal expansion of an ideal gas, the work done by the gas is 2276.6 J, there is no change in internal energy, and the heat added to the system is also 2276.6 J.
