Under some conditions, the liquid phase is skipped, and the substance passes directly from the solid to the gas. This is called sublimation. As example Dry ice, CO2.The rate of sublimation depends on temperature, air pressure, and the solid in question. CO2 molecules are attracted to each other only by a very weak force called the "van der Waals" force. Since the molecules are very weakly attracted to each other, CO2 molecules will go from the solid state to the gas state at low temperatures.

Matter passes from a solid to a gas without passing through a liquid phase?
When A Solid Changes Directly To A Gas With Out Going To A Liquid First It Is Called Sublimation. There is one common object that performs sublimating, and that is dry ice.
The process by which ice changes directly into a gas?
It can sublimate (go directly from a solid to a gas). This could be explained if the ice is moved from an extremely cold environment into an extremely hot environment wihout time to melt.
When did the penitentes form?
If you mean when did they form then the answer is all the time!!If you mean how did they form, then (I did write this myself):Made of compressed snow and ice, these pinnacles only form above 4000m, through the process of sublimation. Sublimation is when a substance goes from the solid phase to the gas phase without passing through the liquid phase. This happens due to the dry air in high altitudes. Some areas sublimate faster than others are, resulting in random depressions in the surface of the snow. Sunlight is focused on these curved areas, causing them to sublimate even faster, forming the tall spikes (penitents).
What are examples of sublimation besides dry ice?
Water can sometimes sublimate from solid ice to water vapor. Iodine sublimates from a solid to gas form when heated and does not often enter the liquid stage. Arsenic and naphthalene are other substances that are prone to sublimation, and other substances can sublimate in certain unusual circumstances.
How does wax change when it melts?
While during the time it melts, wax is very viscous and 'sloppy'. After melting, it is just as fluid as most liquids are.
Is the amount of water the same after the solid ice change phase to its initial form as an ice water?
A phase change does NOT chance the total number of molecules. There will be some evaporation and sublimation too. During the time that ice melts there will some molecules that sublimate to water vapor and also some water molecules evaporate to vapor. But the total mass and number of molecules will not change.
Is a snowman liquid solid or gas?
A snowman is a solid when it's done being built, and is a liquid when it melts away. The only time that it would turn gas was if you poured boiling water over it.

What is the difference between casting and forging?
casting is that in which the metal melts in liquid form by heating and drawn in the mould. after some time it takes a shape of mould. forging is that in which the metal heated (at that point in which it is in a solid form) and took the shape by hammering, punching, pressing etc.

Is lolly pops a solid or a liquid?
When we suck it, it is solid but after some time it becomes liquid
