The Akedah Gained Prominence in the Late Roman Period. The Akedah, orâBinding of Isaacâ, is the account in the book of Genesis (22: 1-19)of Abraham, at the command of God, taking his son, Isaac, to be offered as a sacrifice on Mount Moriah.
Sublimation is the scientific process in which solids are changed to gases without passing through the liquid phase. Sublimation occurs when temperatures and pressures are below the triple point. The triple point is the temperature and pressure at which substances can coexist in solid, liquid and vapor forms.
For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water. The opposite of sublimation is deposition, where water vapor changes directly into iceâsuch a snowflakes and frost. It is not easy to actually see sublimation occuring, at least not with ice. One way to see the results of sublimation is to hang a wet shirt outside on a below-freezing day.
