Sublimasi (kimia): Perbedaan antara revisi

'''Sublimasi''' adalah perubahan wujud dari padat ke gas tanpa mencair terlebih dahulu. Misalkan [[es]] yang langsung menguap tanpa mencair terlebih dahulu. Pada At normal pressures, most chemical compounds and elements possess three different states at different temperatures. In these cases the transition from the solid to the gaseous state requires an intermediate liquid state. However, for some elements or substances at some pressures the material may pass directly from a solid into the gaseous state. This can occur if the atmospheric pressure exerted on the substance is too low to stop the molecules from escaping from the solid state.
