What is the usefulness of latent heat of vaporization?
Because the heat of vaporization is so large, steam carries a great deal of thermal energy that is released when it condenses, making water an excellent working fluid for heat engines. Latent heat arises from the work required to overcome the forces that hold together atoms or molecules in a material.
What is latent heat How is latent heat an important source of atmospheric energy?
When the molecules return to a liquid state the latent heat is released as sensible heat (heat you can feel basically). It is important in the atmosphere because it is the primary factor involved in the formation of convective clouds and the stability/instability of the atmosphere.
What is latent heat give its units with the help of a suitable graph explain the terms latent heat of fusion and latent heat of vaporization?
Latent heat can be defined as the amount of heat energy required by a matter to change its state without changing its temperature. Latent heat of the solid means that amount of heat energy absorbed when 1 kg of a substance changes from solid to liquid at its melting point is called latent heat of fusion of the solid.
How is latent heat an important source of atmospheric energy?
How is latent heat an important source of atmospheric energy? When water vapor condenses into clouds, latent heat is released into the atmosphere. This provides a tremendous amount of heat in storms, such as thunderstorms and hurricanes.
Why latent heat is important for the redistribution of energy?
(See Figure E) The energy that must be added to or removed from water as it changes phases is called latent heat. The latent heat absorbed or released by water is necessary because the water molecules must change their chemical bonding patterns and internal energy to change phase.
What is meant by latent heat explain the role of latent heat in the change of state of a substance?
During the phase change of a substance, its temperature does not increase and hence its kinetic energy. Thus, the heat supplied during phase transformation is used up in increasing or decreasing the potential energy and this heat energy is known as latent heat.
How is latent heat an important source of atmospheric energy quizlet?
What is the role of latent heat in thunderstorms?
Latent heat plays a very important role in thunderstorms and hurricanes. When the water vapor condenses to form clouds, it releases latent heat into the atmosphere. The latent heat then warms the surrounding air around the new cloud droplet causing instability.
Why is latent heat important in the water cycle?
The latent heat absorbed or released by water is necessary because the water molecules must change their chemical bonding patterns and internal energy to change phase. Thus, latent heat refers only to the energy that must be added to or removed from water to cause phase changes.
Does water absorb or release latent heat during evaporation?
Water also absorbs heat when it evaporates. This heat supplies the energy needed to break the hydrogen bonds that hold molecules together. Because it is used to break the hydrogen bonds between individual molecules, this heat does not raise the temperature of the liquid water.
What is the formula of latent heat of vaporisation?
What is the formula for latent heat of vaporization? The latent heat of vaporization for water is 22.6 x 10^5 J/kg. This means that 22.6 x 10^5 J of heat energy must be added to turn one kilogram of water from liquid to gas at 100 degrees Celsius. This graph shows how the temperature of water changes with added heat.
What is the cause of latent heat?
The heat that causes these changes is called latent heat. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air.
Why does the latent heat of vaporization represent?
The heat energy required to change a unit mass of a substance from liquid to a gaseous state at its boiling point without a change in its temperature is called the latent heat of vaporization. It is represented by H v. Its S.I unit is J/kg. Its formula is given as:
