Experiment a respect the first law of thermodynamic.

Materials:

2 cup of coca.

1m de wire.

kerosene.

1 boat with water.

1 syringe.

The object of experience:

Show in the concept practice one application for the first law about thermodynamic , where the cup will be the model on system close thermodynamic.

Application:

After introduce energy at system in the form of heat, the water stay inside the cup, start get hot when enter in ebullition, passing the state of liquid for boiling, grow up the quantity inside the cup, giving grow up together the press inside the cup, the only way to giving the press in for the role, cause the movement the cup.

With this having star the first law of thermodynamic, where the part of energy get start for realized work, and another part of energy get absolved for the system, turn energy inside do system(/\u).

Where:

/\u = 0

/\u = q - w

W > 0.
