The ligament on the inside of the knee becomes stretched and if the force is great enough, some or even all of the fibres will tear.
As moist air is lifted and cooled, water vapor eventually condenses, which then allows for huge amounts of latent heat energy to be released, feeding the storm. 1  Condensation is a warming process. 2  Latent heat of fusion describes both changing from solid to liquid and from liquid to solid.
Because the condenser is maintained at a lower energy level relative to the product ice, the vapors condense and turn back into solid form (ice) in the condenser. The sublimated ice accumulates in the condenser and is manually removed at the end of the freeze drying cycle (defrost step).
