A substance changes from the liquid state to the gas state when enough heat is added for the temperature to be equal or greater than its boiling point. Example: Water begins turning into a gas when it reaches 100 degrees C, which is the boiling point of water
The liquid to gas phase transformation (evaporation) is an endothermic process. It requires heat to be accomplished. The gas to liquid phase transformation (condensation) is an exothermic process. The vapor releases heat while condensing into a liquid.
To melt refers to the transformation from solid to liquid (think ice to water) To condense refers to the transformation from gas to liquid (think steam to water)
Dry ice is the solid form (state of matter) of carbon dioxide (CO2).Under normal circumstances, it will change state from a solid directly to a gas. It does this without melting (changing state to a liquid). We call the direct transformation of a solid to a gas sublimation, and dry ice is said to sublime when going directly from its solid state to a gas.
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. Evaporation is the releasing of molecules from the surface of a liquid and transformation in a gas.
a liquid turns into gas when it is heated...
The transformation of a liquid to a gas is called evaporation. This occurs when the molecules in a liquid gain enough energy to escape into the air as gas.
Evaporation - or boiling.
Condensation is the transformation of a gas in a liquid.
From boiling water, we can observe a transformation of a substance from a liquid to a gas.
The liquid to gas phase transformation (evaporation) is an endothermic process. It requires heat to be accomplished. The gas to liquid phase transformation (condensation) is an exothermic process. The vapor releases heat while condensing into a liquid.
Evaporation
Evaporation is the transformation of a liquid in a gas.
Evaporation if the transformation is at the surface of the liquid and boiling if the transformation involves the entire volume.
Solid--> liquid--> gas.
The transformation of a liquid to a gas.
Evaporation is the transformation of a liquid in a gas.
To melt refers to the transformation from solid to liquid (think ice to water) To condense refers to the transformation from gas to liquid (think steam to water)
