The latent heat of vaporization of light diesel oil typically ranges from approximately 200 to 300 kJ/kg, depending on its specific composition and temperature. This is the amount of energy required to convert diesel oil from liquid to vapor without changing its temperature. The exact value can vary based on the specific formulation of the diesel and environmental conditions.

What are the applications of latent heat of fusion and latent heat of vapourisation?
The latent heat of fusion is the amount of heat required to change a substance from solid to liquid at its melting point, while the latent heat of vaporization is the amount of heat required to change a substance from liquid to gas at its boiling point. These concepts are important in processes like melting and boiling of substances, refrigeration, and even in weather phenomena like cloud formation and rain.
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
What is latent heat of vapourization?
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
What is heat called that is stored in the atmosphere as a result of evaporation?
the answer is latent Latent heat is correct, but specifically the latent heat of evaporation of (whatever is evaporated, in this case water) water. When the evaporated water condenses, it releases this latent heat as it precipitates, which is why it tends to feel warmer during rainstorms (unless the water is running down your neck in which case it feels horrible).
What is the heat that is released when water condenses and changes to liquid form?
The heat released when water condenses and changes to liquid form is called the latent heat of condensation. This heat is released because the water vapor loses energy as it transitions to a liquid state, leading to a release of thermal energy.
Why is latent heat of vapourisation higher than latent heat of fusion?
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
What are the factors that affect specific latent heat of fusion of a substance?
The amount of energy needed to change the "state of matter" is termed as "latent heat". This is not same for vapourisation (liquid to vapour) or for fusion (solid to liquid). For example, latent of fusion is 79.7 cal whereas latent heat for vapourisation is 541 calories. The latent depends on how closely the atoms and molecules in the matter are closely packed.
Why do people wear cotton clothes in summer?
as cotton absorbs sweat, sweat is mainly made up of water and some salts this water takes the heat energy from our body and undergoes latent heat of vapourisation (changing of state of matter) .Due to latent heat of vapourisation water changes its form to water vapour and goes in the surrounding's. this makes the body cool and comfortable.
What is the Latent heat of vapourisation of ethanol?
The latent heat of vaporization of ethanol is approximately 38.6 kJ/mol at its boiling point of 78.37°C. This is the amount of energy required to transform a liquid into a gas at a constant temperature.
What are the applications of latent heat of fusion and latent heat of vapourisation?
The latent heat of fusion is the amount of heat required to change a substance from solid to liquid at its melting point, while the latent heat of vaporization is the amount of heat required to change a substance from liquid to gas at its boiling point. These concepts are important in processes like melting and boiling of substances, refrigeration, and even in weather phenomena like cloud formation and rain.
What is the symbol for latent heat?
The symbol for latent heat is ( L ).
How is steam created?
steam is created by the vapourisation of water (gaseous state of water is the steam). Steam is the result of a liquid changing to a gas. Liquid+heat=latent point of vaporization+additonal heat=steam. I could give you the delta change formula but lets use the kiss method
How many kg of oil are needed to turn 150 kg of water at 100C into steam the burning of 1 pound of oil provides 5.74x10raised to the 6th power calories of heat?
Latent heat of vapourisation of Water is 2257 KJ/Kg = 2257*0.24 kcal/Kg = 541.68 kcal/kg Since the temp of water is 100 deg C, and the boiling point is 100 it is sufficient if we provide the latent heat of vapourisation. The total amount of heat required is =150 *541.68 = 81252 kcal… Energy we get by burning 1 pound of oil = 5.74 * 10^6 cals =5740 kcals Total quantity of oil required =81252/5740 = 14.155 pounds = 6.4 kgs
What is latent heat evaporation?
Latent heat of evaporation of water to steam is 2270 KJ/Kg
What is the heat stored in the atmosphere as a result of evaporation?
Latent
What is the opposite of latent heat?
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
