Which liquid has highest latent heat of vaporization?
water
The heat of vaporization of water is the highest known. The heat of vaporization is defined as the amount of heat needed to turn 1 g of a liquid into a vapor, without a rise in the temperature of the liquid.
What is the specific heat of liquid nitrogen?
Specific heat capac- ity of liquid nitrogen is equal to cp ≈ 2 kJ∙kg-1∙K-1, latent heat of vaporization at these temperatures is about L ≈ 200 kJ∙kg-1 [1, 2].
What is the latent heat of vaporization from liquid to gas?
The enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas.
What is latent heat of vaporization?
Latent heat of vaporization is the heat consumed or discharged when matter disintegrates, changing state from fluid to gas state at a consistent temperature. The heat of vaporization of water is the most elevated known.
Which substance has highest latent heat?
Ice has a latent heat of fusion of 334 kJ/kg and is the highest. Was this answer helpful?
How do you calculate latent heat of vaporization?
Latent heat calculation The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .
What is the latent heat of liquid nitrogen?
PL-2) The accepted value for the latent heat of vaporization of liquid nitrogen is 199,200 J/kg.
What is the latent heat of nitrogen?
Specific heat of Nitrogen is 1.04 J/g K. Latent Heat of Fusion of Nitrogen is 0.3604 kJ/mol. Latent Heat of Vaporization of Nitrogen is 2.7928 kJ/mol.
What is latent heat of vaporization with example?
The latent heat of vaporization, which is the heat required to transition matter from the liquid to the vapor phase without changing the temperature. Example: bringing a water kettle to boil; liquid water particles transition to water vapors.
Which liquid has highest latent heat of fusion?
Ice has a latent heat of fusion of 334 kJ/kg and is the highest.
Which substance has the largest latent heat of fusion?
ice
0 °C is the latent heat of fusion and is 80 calories per gram of ice. Water’s latent heat of fusion is the highest of all common materials.
What is the latent heat of vaporization of steam?
As the latent heat of steam at atmospheric pressure is 2257 kJ/kg the amount of flash steam produced will be 299/2257 = 0.133 kg/kg of condensate.
