15.9 Example 9

A certain gas have a volume of 5 liters, at 10 C and 750 mmHg of pressure. What will be the volume at 100 C and 3 atmospheres of pressure?

Solution with FisicaLab

Select the Thermodynamics group and, inside this, the Calorimetry and gases module. Erase the content of the chalkboard. And add one element Gas PV/T, as show the image below:

To this element, with the corresponding conversion factors, we have:

Pi

750 @ mmHg

Vi

5 @ L

Ti

10 @ C

Pf

3 @ atm

Vf

Vf @ L

Tf

100 @ C

Now click in the icon Solve to get the answer:

Vf = 2.162 L ;
Status = success.
