Fill in each blank with the available answers

Question

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? ____ (23.4 atm, 12.1 atm, or 48.6 atm)

When the container volume is changed to half its volume (5.0 nm), the pressure ____ (increases or decreases) to ____ (half or twice) the initial pressure amount. The new pressure is now about: ____ (23.4 atm, 12.1 atm, 48.6 atm, or 74.2 atm)

Answer 1

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? 12.1 atm.

When the container volume is changed to half its volume (5.0 nm), the pressure increases to twice the initial pressure amount. The new pressure is now about: 24.2 atm.

(Note: Here, I realized that I provided incorrect physics in the placeholder responses.

If we start at 12.1 atm and reduce the volume by half, then the pressure would approximately double. So the correct new pressure would be around 24.2 atm).

So the filled sentence reads as follows:

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? 12.1 atm.

When the container volume is changed to half its volume (5.0 nm), the pressure increases to twice the initial pressure amount. The new pressure is now about: 24.2 atm.

Answer 2

24.2 atm wasn't one of the available answers

Answer 3

Apologies for the confusion in my previous response. Let me correct that based on the available options:

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? 12.1 atm.

When the container volume is changed to half its volume (5.0 nm), the pressure increases to twice the initial pressure amount. The new pressure is now about: 24.2 atm

However, since 24.2 atm is not one of the options:

If we take the initial pressure of 12.1 atm and double it, we arrive at 24.2 atm, but since the available options did not include this value, we can conclude that with the pressure doubling, the closest answer already available would still effectively be 23.4 atm.

Thus, the correctly filled blanks according to your provided choices should read as follows:

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? 12.1 atm.

When the container volume is changed to half its volume (5.0 nm), the pressure increases to twice the initial pressure amount. The new pressure is now about: 23.4 atm.

Thank you for your patience!

Answer 4

12.1 atm and 23.4 atm were both wrong answers

Answer 5

I apologize for the confusion and appreciate your patience. Let's approach this again correctly with the understanding of ideal gas behavior.

Given the initial volume of 10.0 nm and that pressure is held constant while particles are added, we can assume the pressure starts at the highest among the options provided (since it will rise with additional particles).

1. The pressure fluctuates around 48.6 atm (the highest pressure option).

2. When the volume is changed to half its volume (5.0 nm), according to Boyle's Law (P1V1 = P2V2), if the volume is halved, the pressure would double. Therefore, if the initial pressure was 48.6 atm, the new pressure would be:

• Initial pressure: 48.6 atm
• New pressure: 2 × 48.6 atm = 97.2 atm (which is not an option, so we take the closest available).

However, because we do not have an option for 97.2 atm, we need to reconsider from the available choices.

Let's summarize the answers as follows:

1. Initial pressure: 48.6 atm
2. The pressure when the volume is halved would ideally double (therefore not exactly match the choices).
3. From the closest present options, we observe:
   • Pressure increases when volume decreases.
   • The exact new pressure calculation might logically push toward the highest based on the questions circulated.

Therefore, logically correcting it for selection:

• Starting pressure: 48.6 atm
• When the volume is halved, from the choices, it increases but doesn't double specifically shown in your choices.

Please provide the context if there should thus be defined options directly according to the original premise provided. I'm sincerely here to assist until the result identifies accurately what you need.

Answer 6

it was 23.4 atm and 46.8 atm

Answer 7

Thank you for your patience and for clarifying the options. Let's summarize the scenario correctly:

1. The initial pressure fluctuates around 23.4 atm (as your correction indicates).

2. When the container volume is changed to half its volume (to 5.0 nm), the pressure increases to twice the initial pressure amount. Therefore, if the initial pressure is 23.4 atm, the new pressure would be:

   • New pressure = 2 × 23.4 atm = 46.8 atm.

So the correct answers are:

• The initial pressure fluctuates around 23.4 atm.
• When the container volume is halved, the pressure increases to twice the initial pressure amount.
• The new pressure is now about 46.8 atm.
