sublimaatiokäyrän

Sublimaatiokäyrä refers to the phase diagram boundary between the solid and gas phases of a substance. Along this curve, the solid and gas phases are in equilibrium, meaning that a substance can transition directly from solid to gas (sublimation) or from gas to solid (deposition) at a given temperature and pressure. The sublimation curve starts at absolute zero and extends to the triple point. At pressures below the triple point pressure, sublimation is the only possible phase transition between solid and gas. As pressure increases, the sublimation temperature also increases. The sublimation curve is a fundamental concept in thermodynamics and physical chemistry, helping to understand the behavior of matter under various conditions.
