Formula of solid pressure, liquid pressure and gas pressure What does the letter mean

Solid: P = f / SP: pressure, F: pressure, s: force area of object, gas and liquid: P = ρ GHP: pressure, ρ: density of liquid or gas, G: constant, i.e. 9.8n/kg, H: height

How are gases, solids and liquids converted

Gases liquefy into liquids and condense into solids
Liquid is exothermic and solidifies into solid, endothermic and vaporizes into gas
A solid absorbs heat, melts into a liquid and sublimates into a gas
