When grains move closer together, eliminating spaces, they have compacted.
When you cool them down.
When ANY two objects move closer together, the gravitational forces between them become greater.
3 times closer
In terms of particles, "compression" means that particles move closer together.
When grains move closer together, eliminating spaces, they have compacted.
I would have thought that once the (dry) grains were removed from the constraints of a sack, gravity would make them spread out. The only other thing would be, is that the grains are moist. This moistness would tend to make them keep in a more upright clump!
No. When air cools air particles move closer together. When air warms air particles move father away from each other.
When a gas turns into a liquid, its called condensation. The particles slow down and move closer together.
When you cool them down.
Convergence.
No. They move closer together so they can share what little heat they have.
they move away from each other!
As you move them closer and closer together, the repellent force between them will get stronger and stronger.
When ANY two objects move closer together, the gravitational forces between them become greater.
The particles move closer together and are practically so close they cannot move.
Move the objects closer together.
