Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a solid moves directly to a gas it is known as
A
condensation
B
sublimation
C
precipitation
D
freezing
Explanation: 

Detailed explanation-1: -Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.

Detailed explanation-2: -Sublimation is the transition of a substance directly from the solid phase to the gas phase without passing through the intermediate liquid phase (Table 4.8, Fig. 4.2). Sublimation is an endothermic phase transition that occurs at temperatures and pressures below the triple point of a chemical in the phase diagram.

Detailed explanation-3: -Sublimation is the change of state from a solid to a gas, without passing through the liquid state. Deposition is the change of state from a gas to a solid. Carbon dioxide is an example of a material that easily undergoes sublimation.

Detailed explanation-4: -Sublimation is the process in which solid directly changes to gas.

Detailed explanation-5: -Sublimation: The process in which a solid transforms into a gas phase without first melting to form a liquid phase. (Sublimation is not synonymous with evaporation; evaporation is a liquid-to-gas phase change.) Frequently happens with substances having a high vapor pressure at room temperature.
