Using A Thermodynamics Calculator

Our thermodynamics calculator is a great tool in the world of energy transformation. It is so simple that anyone can use it effortlessly. You just need to enter details about the material in your system, such as pressure, volume, temperature, etc. The calculator will provide you with instant results.

  1. Enter the type of Process: There are three types of thermodynamic systems isothermal (constant temperature), diabatic (no heat transfer), isobaric (constant pressure), and isochoric (constant volume). So enter any one of them.
  2. Enter the Pressure: In the second step, enter the pressure of the fluid (liquid or gas) that you are using in your system.
  3. Enter the Temperature: Now, enter the present temperature of the system.
  4. Enter the Volume: Enter the volume of the whole system. 

Click the calculate or submit button to process the information. The calculator will use the provided details to perform the necessary computations and display the results.

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.
