Answer:
the pressure of the gas in container A will remain constant as the temperature is lowered
Step-by-step explanation:
To answer the question, we need to consider the gas laws and how they relate to changes in temperature, pressure, and volume of a gas.
Based on the information given, we know that the temperature of the gas in container A is being lowered from 298 K to 100 K, while the container is kept rigid, meaning its volume cannot change.
The gas law that applies to this scenario is Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature. Since the volume is constant in this case, we can conclude that the pressure of the gas must also remain constant.
Therefore, the answer to the question is: the pressure of the gas in container A will not change.
The following changes will occur to the gas in container A as the temperature is lowered from 298 K to 100 K:
- The average kinetic energy of the gas particles will decrease.
- The gas particles will move more slowly and have less momentum.
- The frequency of the gas particle collisions with the container walls will decrease, leading to a decrease in the force exerted by the gas on the container walls.
- The density of the gas will increase (assuming the number of gas particles remains constant), since the same number of particles will be occupying a smaller volume due to the decrease in temperature.
In summary, the pressure of the gas in container A will remain constant as the temperature is lowered, while the other properties of the gas will change.
