Force Table Lab
Force table simulation to study the composition and decomposition of forces and analyze/understand vectors. Choose the masses and angles and seek the system equilibrium.
Thermodynamics
Linear Interpolation for Steam Tables
Perform single or double linear interpolations to determine thermodynamic properties on the gaps of steam tables. Although it is built for steam tables, it is valid for any data table.
Thermodynamic properties of ideal gases
Calculate the internal energy, enthalpy and entropy of various substances in the ideal gas condition. Use the available database or use your own constants.
Interpolation and thermodynamics properties calculator (Excel) (in portuguese)
Excel workbook to aid thermodynamics classes, there is a sheet for interpolations, ideal gas enthalpy, ideal gas entropy (temperature), and saturation pressure. Unfortunately, in Portuguese.
Simple Water Steam Property Calculator
Thermodynamic properties of water by IAPWS (International Association for the Properties of Water and Steam) formulations.
Water Specific Heat Capacity Lab (Excel) (in portuguese)
Excel simulation of an experiment to determine the specific heat of the water. Heat water using electrical resistance, specify the potential difference and turn on agitation. Measure temperatures over time, and analyze the data to determine the specific heat of the water. Unfortunately, in Portuguese.
Reversible Work Interactive Animation (Geogebra)
GeoGebra for reversible work demonstration. Divide a block of mass m and compress or expand a piston-cylinder in n steps. The greater the number of steps, the greater the expansion work and the less compression work. In the limit of infinite steps, we determine the reversible process.
Carnot Cycle Animation(without menu) press F11 for fullscreen
Carnot Cycle Animation, visualize the four transformations of the cycle and the path taken by the system in a pressure-volume (Pv) diagram.
EOS Properties Calculator
Calculator for thermodynamic properties of pure substances. Determine the value of the compressibility factor Z, fugacity coefficient φ, specific volume, and residual internal energy, enthalpy, and entropy. Use the available database or use your constants.
EOS Properties Calculator (Google Colab) in portuguese

Find the ideal gas properties and saturation temperature or pressure. Use the available database or use your constants. In Google Colab. Unfortunately, in Portuguese.
Water-Ethanol Mixture Volume Lab (Excel) in portuguese
Excel simulation of the mixture between a given mass of water and ethanol. Check mixing volume. Is volume additive? Unfortunately, in Portuguese.
Molecules Interaction Simulation
It is a simple colliding balls simulation to show the effect of the concentration of different species in a mixture. It counts the number of times a cyan ball collides with a blue or a red ball.
Mixture Properties
Geogebra that shows the pure substance enthalpy, partial molar enthalpy, enthalpy of mixture and the mixture enthalpy.
Water-Ethanol Gas-Liquid Equilibria Lab (Excel) (in portuguese)
Excel simulation of an experiment to determine the constants of an activity model. The experiment was developed to determine the constants of the van Laar activity model. Unfortunately, in Portuguese.
