In a rotary tablet press, both upper and lower punches do what to the powder to form the tablet?

Explanation:
Compression of the powder into a solid tablet is what happens. In a rotary tablet press, the powder fills the die between the upper and lower punches, and as the machine operates, both punches move toward each other. The resulting compressive force rearranges particles, causes them to deform and bond, and reduces porosity so a cohesive, solid tablet is formed. This is different from dissolving (which would require a solvent), melting (which needs heat to liquefy), or evacuating (which would remove air or material rather than create a solid compact). Compression is the mechanism that creates the tablet.
