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.
Is latent heat of vaporisation fixed?
No, the latent heat of vaporization is not fixed and can vary depending on the substance. It represents the amount of energy required to change a unit mass of a substance from liquid to gas at a constant temperature and pressure.
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.
What energy is required to create a phase change without changing the temperature?
The energy required to create a phase change without changing the temperature is known as latent heat. This energy is needed to break the intermolecular forces holding the molecules in a particular phase, such as solid to liquid or liquid to gas, without increasing the temperature of the substance.
Is specific latent heat of ice is same for water or not?
The specific latent heat of ice and water is not the same. The specific latent heat of fusion for ice (the heat required to convert ice to water at 0°C) is approximately 334 kJ/kg, while the specific latent heat of vaporization for water (the heat required to convert water to vapor at 100°C) is significantly higher, around 2260 kJ/kg. Thus, the energy required for phase changes differs between ice and water.
What is specific latent heat of vaporisation?
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
What physical properties are size indepentent?
There are very many. Some are:Density (and specific gravity), electrical conductivity, thermal conductivity, boiling point, latent heat of vaporisation, melting point, latent heat of melting, elasticity, malleability, ductility, electronegativity (though that could be considered a chemical property), temperature.
Why do you feel cool after you perspire?
Because as water evaporates it absorbs latent heat of vaporisation
Why the time needed to vaporize a sample is greater than the time needed to melt a sample?
The amount of time depends on the latent heat of vaporisation and the latent heat of melting.
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.
Is latent heat of vaporisation fixed?
No, the latent heat of vaporization is not fixed and can vary depending on the substance. It represents the amount of energy required to change a unit mass of a substance from liquid to gas at a constant temperature and pressure.
What do you call the heat energy that is released or absorbed during a change of state of water?
The heat energy released or absorbed during a change of state of water is called latent heat. This energy is used to break or form intermolecular bonds without changing the temperature of the substance.
What is the name of the process in which liquid water turns into water vapour?
this process is called evaporation. it occurs when the bonds break, due to the average amount of energy, the temperature, going up enough to provide the latent heat of vaporisation. the latent heat of vaporisation is merely the name of the energy amount that it takes to break the bonds.
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.
What is the relationship between specific heat and latent heat in the context of thermal energy transfer?
Specific heat and latent heat are both properties of a substance that determine how it absorbs or releases thermal energy. Specific heat refers to the amount of heat required to raise the temperature of a substance by a certain amount, while latent heat is the amount of heat needed to change the state of a substance without a change in temperature. In thermal energy transfer, specific heat affects the temperature change of a substance, while latent heat is involved in phase changes such as melting or boiling.
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.
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
