Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What phase change is demonstrated when a substance is changed from a liquid to gas?
A
freezing
B
vaporization
C
deposition
D
sublimation
Explanation: 

Detailed explanation-1: -Temperature changes during a phase change. The process of a liquid becoming a gas is called sublimation.

Detailed explanation-2: -Evaporating: The transition from the liquid phase to the gas phase.

Detailed explanation-3: -Condensation: the substance changes from a gas to a liquid.

Detailed explanation-4: -Vaporization-Liquid to gas (included boiling and evaporation) Sublimation-Solid to gas. IonizationGas to plasma.

Detailed explanation-5: -All phase changes are accompanied by changes in the energy of a system. Changes from a more-ordered state to a less-ordered state (such as a liquid to a gas) are endothermic. Changes from a less-ordered state to a more-ordered state (such as a liquid to a solid) are always exothermic.
