Physics - Thermodynamics - Latent heat - Latent Heat Explained

A 5-step lesson. Step 1: 'Latent heat is the energy needed to change the state of a substance WITHOUT changing its temperature. Q = mL.' Two types: Latent heat of fusion (Lf, solid↔liquid) and Latent heat of vaporization (Lv, liquid↔gas). Step 2: 'For water: Lf = 334,000 J/kg (melting/freezing). Lv
