Question

reset the simulation. having observed the relationship between temperature and pressure of heavy gas particles, follow these steps to observe the relationship between temperature and pressure of the light gas particles:

1. add 50 \light\ particles to the container. observe the pressure.
2. increase the temperature of the container to approximately 400 k, observing the resulting pressure on the gauge.

which statements describe what you observed? choose two correct answers.

• increasing the temperature of the container resulted in an increase in pressure.
• increasing the temperature of the container resulted in a decrease in pressure.
• the pressure at 400 k was 2.5 atm.
• the pressure at 300 k was 5.8 atm.

Explanation:

Analyze the relationship between temperature and pressure

Using the Pressure-Volume-Temperature Relationships and Gas Laws knowledge points

$$ P \propto T \quad (\text{at constant } V, n) $$

An increase in temperature from approximately \(300\text{ K}\) to \(400\text{ K}\) must result in an increase in pressure.

Determine the quantitative pressure values

Using the Gas Laws knowledge point

$$
LATEXBLOCK0
$$

Thus, the pressure at \(300\text{ K}\) is \(5.8\text{ atm}\), and it increases as temperature increases.

Answer:

• Increasing the temperature of the container resulted in an increase in pressure. (Correct answer)
• Increasing the temperature of the container resulted in a decrease in pressure.
• The pressure at 400 K was 2.5 atm.
• The pressure at 300 K was 5.8 atm. (Correct answer)
