500 mL of He at 98 kPa expands to 750 mL. Find P2.

Explanation:

According to Boyle's law, which mathematically describes the thermodynamic process in which the pressure of a gas has the tendency to increase as the volume of the container decreases, we have:

(1)

Where:

is the initial pressure of Helium (He)

is the initial volume of Helium (He)

is the final volume of Helium (He)

is the final pressure of Helium (He)

Now, we need to isolate from (1):

(2)

(3)

Finally:

This is the final pressure of Helium

what's the
