Which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant? 1. An increase in pressure causes particles to move closer together, increasing the volume.

2. An increase in pressure causes particles to move closer together, decreasing the volume.

3. An increase in pressure causes particles to move farther apart, increasing the volume.

4. An increase in pressure causes particles to move farther apart, decreasing the volume.

Explanation:

Because the pressure in the air, it’s causes particles to move farther apart from each other.

it breaks and dirupture other materials and other sencews from the bottom

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
