Phase Change

#Physics #Chemistry

$\displaystyle Q=mL$

• $\displaystyle Q$ is the heat gained or lost from the material during the phase change
• $\displaystyle m$ is the mass of the material
• $\displaystyle L$ is the heat of transformation or latent heat of the substance

Types of Phase Change

• Solid to liquid: fusion/melting
• Liquid to solid: freezing or solidification
• Liquid to gas: boiling, evaporation, or vaporization
• Gas to liquid: condensation
• Solid to gas: sublimation
• Gas to solid: deposition
