latent heat

• Quantidade de energia térmica absorvida ou liberada por uma substância durante uma mudança de fase (como fusão, solidificação, vaporização ou condensação) a temperatura e pressão constantes.

The amount of heat energy absorbed or released by a substance during a phase change (such as melting, freezing, vaporization, or condensation) at a constant temperature and pressure.

1. Hidden thermal energyC1formal

   The amount of heat absorbed or released by a substance during a phase change (e.g., melting, boiling) without a change in temperature.

   Calor latente

   • The latent heat of fusion is the energy needed to melt ice into water.
   • During condensation, latent heat is released into the atmosphere.
   • Engineers calculate latent heat to design efficient cooling systems.
