In the virtual lab demo, a student adds particles to a container. While the temperature is held constant the initial volume of the container is 10.0 nm. The pressure fluctuates around what amount?

When the container volume is changed to half its volume (5.0 nm), the pressure pressure is now about:

To analyze the situation in the virtual lab demo regarding the behavior of particles in a container while maintaining constant temperature, we can apply the principles outlined in the ideal gas law, which states:

\[ PV = nRT \]

Where:

  • \( P \) is the pressure,
  • \( V \) is the volume,
  • \( n \) is the number of moles of gas,
  • \( R \) is the universal gas constant,
  • \( T \) is the temperature.

When the temperature is held constant in this experiment (isothermal conditions), we can observe the relationship between pressure and volume as described by Boyle's Law:

\[ P_1 V_1 = P_2 V_2 \]

Where:

  • \( P_1 \) and \( V_1 \) are the initial pressure and volume,
  • \( P_2 \) and \( V_2 \) are the final pressure and volume.
  1. Initial Conditions:

    • Volume (V1) = 10.0 nm
    • Since we don't have a specific value for pressure \( P_1 \), we can call this initial pressure \( P_1 \).
  2. Final Conditions with Volume Halved:

    • New Volume (V2) = 5.0 nm

Using Boyle's Law, we can express the final pressure \( P_2 \):

\[ P_1 \cdot 10.0 , \text{nm} = P_2 \cdot 5.0 , \text{nm} \]

Rearranging this gives:

\[ P_2 = P_1 \cdot \frac{10.0 , \text{nm}}{5.0 , \text{nm}} \]

\[ P_2 = 2 \cdot P_1 \]

This indicates that when the volume of the container is halved, the pressure will approximately double.

To summarize:

  • If the initial pressure fluctuates around \( P_1 \) when the volume is 10.0 nm, when the volume is changed to 5.0 nm, the pressure is expected to fluctuate around \( 2P_1 \).

If you have a specific initial pressure value in mind, you can multiply that by 2 to find the approximate new pressure.
