Sublimation;0

Have you ever wondered about Astronaut Food??? This type of food has to do with Sublimation! Sublimation is when a solid goes straight to a gas without going through the liquid phase. Food happens when the temperature increase to be above 32 decrees F. The surround pressure must be below 0.06 atmosphere. When this happens the water inside liquid melts and it lacks the pressure to become a liquid becoming a gas!!!
