This equation is known as the general ideal gas law, and because it relates the specific conditions or state, that is, the pressure, volume, and temperature of agiven mass of gas, it is called the equation of state of an ideal gas. Real gases do not interact without energy exchange, and therefore do not follow the laws of Boyle and of Gay-Lussac and Charles as ideal gases are assumed to do.

The energy required to reduce the size of particles is inversely proportional to the size raised to some power.

Mechanisms of Comminution
Mills are equipments designed to impart energy to the material and cause its size reduction. There
are three main methods of effecting size reduction.

Pin mill: https://pharmatech-rx.com/pin-mill/

is a method of comminution that acts by producing particle impact and attrition. Particle size reduction occurs by impaction with the pins and by attrition between pins as the particles travel outwards under the influence of centrifugal force.

Why tetracycline should not be taken with antacids, milk and iron?

Milk and other dairy products, antacids containing polyvalent cations, and various iron salts form complexes with tetracycline derivatives, making them insoluble and poorly absorbable. This interaction can reduce the absorption of tetracyclines by 50 to 90%, or even more.
