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.


Why you use ice in the hydrolysis of ethyl acetate?

Ice is used in the hydrolysis of ethyl acetate to help regulate the temperature of the reaction. The hydrolysis reaction is exothermic, meaning it produces heat. By adding ice, the temperature can be controlled to prevent the reaction from getting too hot and potentially boiling over or causing side reactions.


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.


A system that cools the air by spraying water into a tower is called?

The system you are referring to is known as an evaporative cooling tower. It works by using the latent heat of vaporization to cool the air as water is sprayed into the tower and evaporates, absorbing heat in the process.

What step changes liquid water to water vapor?

Vaporization is the change of liquid water to water vapor. Vaporization requires addition of the latent heat of vaporization to liquid water. The latent heat of vaporization supplies the liquid water molecules with enough energy to become vapor molecules. The latent heat of vaporization at 1.0 atmosphere pressure is about 1000 Btu per lbm ( 2260 kJ per kg ).


How your body cooled when you perspire?

Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.


Why does the temperature stops rising during melting and boiling point?

Because the latent heat of fusion and latent heat of vaporization are very high


Heat of vaporization of methyl acetate?

The heat of vaporization of methyl acetate is approximately 31.4 kJ/mol at its boiling point of 57.1°C. This value represents the energy required to convert 1 mole of liquid methyl acetate into vapor at constant temperature and pressure.


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 does L mean in the equation Heat equals mL?

L can either mean the latent heat of vaporization or condensation. The latent heat of vaporization is the energy required to completely turn 1 kilogram of a liquid into a gas at its boiling point. The latent heat of condensation is the energy required to completely turn 1 kilogram of a solid into a liquid at its melting point.


What is the amount of energy required to change a material from a liquid to a gas?

Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy over unit of mass, i.e., KJ/Kg.


What does the latent Of heat of vaporization represent?
