Latent heat of ethanol?
Specific heat of ethanol: 2.46 g/mol*degree CSpecific heat is the heat required to raise the temperature of a given mass by 1 degree Celsius.The formula is Q = cmΔTQ = Heat addedc = Specific heatm = MassΔT = Change in temperature
Why is latent heat important to the atmosphere?
Latent heat is an important form of atmospheric energy. Latent heat is a property of water vapor in the atmosphere and when water vapor condenses it releases latent heat. Latent heat must be supplied to evaporate liquid water and this heat affects the behavior of the weather.
What is the heat of reaction for ethanol fermentation from glucose?
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
Why does steam at 100 degrees Celsius do more damage to the skin than water at 100 degrees Celsius?
The heat content of steam is much greater than of liquid water at the same temperature. That makes that the speed of heat penetration INTO the (deeper parts of the) skin is higher and thus it's effects are more severe. Condensation on skin adds a lot of (condensation) heat to that.
What process releases the latent heat of water vapor to make the air warmer?
1. Process that release "Latent Heat" : a. Freezing, b. Condensation, - (Greatest amount of released Latent Heat.) c. Deposition. 2. Process that absorbs "Latent Heat" : a. Melting, b. Evaporation, - (Greatest amount of absorbed Latent Heat.) c. sublimation.
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 applications of latent heat of fusion and latent heat of vapourisation?
the application of latent heat fo fussion is ice is used to put in drinks to make cool because ice has hih specific heat capcity
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.
Latent heat of ethanol?
Specific heat of ethanol: 2.46 g/mol*degree CSpecific heat is the heat required to raise the temperature of a given mass by 1 degree Celsius.The formula is Q = cmΔTQ = Heat addedc = Specific heatm = MassΔT = Change in temperature
The latent heat of vaporization of ethanol is 200 calories gram. This means that?
about 200 calories of heat must be added to 1 gram of ethanol to convert it from a liquid to a gas
Give you an example of heat transformation?
heat of fusion and heat of vapourisation.
Can latent heat be zero?
No, latent heat can never be zero.Because latent heat is the hidden heat so there has to be heat more than zero.
Draw and discuss the relationship of heat of fusion and heat of vaporization?
There is no relationship between heat of fusion and heat of vapourisation
Heat that causes a substance to change form is called?
latent heat :)
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
