HYBRID gas density for railroad

HYBRID gas density for railroad

Relative particle density for a solid, liquid and gas. When a liquid changes into a gas, the spacing between the particles increases significantly. This means that the gas takes up a lot more space than the liquid, so its volume increases dramatically. When a gas condenses to form a liquid, its volume...
