Since it depends on vaporization, this technique is best suited to compounds that can be vaporized without suffering decomposition.
Thermal energy required to break up the hydrogen bonds and to permit vaporization is available only at the higher boiling temperatures.
Medical cannabis is most frequently administered either by smoking or vaporization or in the form of edible preparations.
The research he performed during the early 1920s elucidated the theory of the entry of high-speed bodies into the atmosphere and was fundamental to the understanding of ablation, the peeling back of meteor surfaces during vaporization.
The cold-batch method ensures a very low emission of decomposition, vaporization, and carryover products; in addition, batches containing fluorides can be melted generally with little or no escape of toxic fluorine.
The manifold hydrogen bonds among water molecules mean that water has a high boiling point and a high latent heat of vaporization compared with other liquids; that is, it takes considerable heat to turn liquid water into steam, which is available when the steam is condensed.
The cuckoopint (Arum maculatum), which has a metabolic level unequaled among plants, spreads its odour over a wide area by an elevation of temperature that increases the vaporization rate of the volatile odour substance.
Sharp and colleagues argued that hydrogen in Earth processes prevented the differential vaporization of chlorine that took place in lunar magmas, and they concluded that the Moon was thus essentially anhydrous.
Special challenges to homogenization can be posed by residual unmelted material from the batch, particularly sand grains, as well as devitrification products, material from the refractory lining of the melting tank, foreign matter such as bottle caps, and vaporization of the various glass constituents, particularly of boric oxide and alkali.
