Question

The speed of the gas molecules contained in a closed vessel at fixed temperature and pressure in the same. ( true or fase )​

Answer 1

Explanation:

When gases in containers are heated, their molecules increase in average speed. This means that they exert a greater force when they collide with the container walls, and also collide with the walls more frequently. The gas is therefore under greater pressure when its temperature is higher.

Answer 2

Answer:

The speed of the gas molecules contained in a closed vessel at fixed temperature and pressure in the same - this is a false statement.

Explanation:

• When gases in containers are heated, the average speed of their molecules increases. As a result, they hit the container walls harder and more frequently, and they also do so with higher power.
• When placed in a closed container, gas expands. The container continues to be filled as the molecules circulate. Each time they hit the container's sides, pressure is created.
• The number of collisions and thus the pressure rise as the number of molecules does. Similar to this, a higher average molecular velocity results in a higher gas pressure.
• It is exceedingly unlikely that every molecule in a larger vessel will move at the same pace. By virtue of collisions, their speeds will disperse in accordance with the Boltzmann distribution law.

Thus, the speed of the gas molecules contained in a closed vessel at fixed temperature and pressure will not be the same.
