A gas occupies a volume of 2000 cm³ at a certain pressure. If the pressure is reduced to 1/5 of its original value while the temperature remains constant, what is the new volume?

Step 1: Identify the given values and the relevant gas law.
The initial volume is $V_1 = 2000 \text{ cm}^3$.
The final pressure is $P_2 = \frac{1}{5} P_1$.
The temperature remains constant ($T_1 = T_2$).
We need to find the new volume $V_2$.
Since the temperature and mass of the gas are constant, we use Boyle's Law, which states $P_1V_1 = P_2V_2$.

Step 2: Substitute the given values into Boyle's Law.
