Specific Latent Heat

• What is specific latent heat?

  Energy required to change state without temperature change
• What happens to temperature when a substance changes state?

  Temperature remains constant during the change
• What is the specific latent heat of fusion?

  Energy to change solid to liquid
• What is the specific latent heat of vaporization?

  Energy to change liquid to vapor
• What is the formula to calculate energy change during a state change?

  Energy = mass × specific latent heat
• What is the specific latent heat of fusion of water?

  334,000 joules per kilogram
• What is the process of calculating energy change during a state change?

  • Use the formula: Energy = mass × specific latent heat
  • Substitute mass and specific latent heat values
  • Calculate the energy in joules
• What are the key differences between specific latent heat of fusion and vaporization?

  • Fusion: solid to liquid
  • Vaporization: liquid to vapor
  • Different energy values required
