Air tight piston experiment. In this experiment, volume was constant inside the container and a small piece of paper was inserted. A force was applied to the piston increasing the pressure inside the container causing the paper to ignite. Since force was applied on the piston, the change in work W was positive. There was a change in heat Q that occurred inside too since there was a spark of ignition. By applying the 1st law of thermodynamics deltaU = Q - W, we can say that there is a positive internal energy that occurred inside the container.
Equation for the air-tight piston experiment.
Graph of isochoric process where in pressure is constant, volume b
Graph of Isothermal Process where in temperature is constant, pressure vs. volume
Graph of isobaric process where in pressure is constant, pressure vs. volume
Prediction before running the simulation.
