Question

define the latent heat of vaporization of water ? Give it value under normal pressure.​

Answer 1

Answer:

LATENT HEAT OF VAPORIZATION IS THE AMT OF HEAT ENERGY REQUIRED TO CONVERT ONE KG OF LIQUID TO GAS

Answer 2

Answer:

When a material in liquid state(l) is given energy, it changes its phase from liquid (l) to vapor (v) ; the energy absorbed in this process is called heat of vaporization( Lv) . The heat of vaporization of water is about Lv (water )= 2,260 kJ/kg, which is equal to Lv(H2O) = 40.8 kJ/mol.
