What is the relationship between energy and phase changes?
Adding or removing energy in the form of heat causes the phase change. The amount of heat to be added or removed is called latent heat. It changes the state of a substance without changing it's temperature. There are two types of latent heat. The latent heat of fusion, and the latent heat of vaporization. The latent heat of fusion must be added to change phase from solid to liquid, and removed to change from liquid to solid. The first change is endothermic and the second change is exothermic. The latent heat of vaporization must be added to change phase from liquid to vapor, and removed to change from vapor to liquid. Again the first change is endothermic and the second change is exothermic.
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
What is the latent heat of fission?
Latent heat of fission is analogous to latent heat of fusion (see http://en.wikipedia.org/wiki/Enthalpy_of_fusion) except that it applies to the state of change from liquid to gas. Also see http://en.wikipedia.org/wiki/Latent_heat.
Are state changes physical or chemical changes?
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Explain why the temperature of Wax remains constant during solidification?
it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only
What are two changes of state for water that cause latent heat to be released?
liquid and gas
What is energy that is stored or released during a change of state of water?
latent heat
What are two changes in state the require the addition of latent potential energy?
Melting of solids and vaporization of liquids.
What is latent state?
Herpes virus that latent in the nerves
What is chronic latent state?
Herpes virus that latent in the nerves
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.
The form of energy related to the change of the state of water?
The energy which must be transferred to or from a sample of water in order to change it's state is called the Latent Energy or Latent Heat - for example Latent Heat of Evaporation or Latent Heat of Freezing.
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.
Does melting cause a change in state?
Yes, the material changes from a solid state to a liquid state.
When a substance changes from one state of matter to another it is call?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
What is the difference of heat and heat capacity?
Heat capacity is the amount of heat something can take before it changes temperature by a degree. If we use water as an example, it is said to have a high heat capacity as you need to heat it a lot before it changes temperature at all. Latent means not yet existing. Latent heat is therefore referring to the amount of heat it would take something for it to change state. Water is said to have a high latent heat of vaporisation. That means that it takes a lot of heat to vaporise water. While heat capacity talks about how much heat something can take, latent heat talks about how much heat something requires to cause a change. Similar concepts but they have slight differences.
When a liquid changes to to soil it is called?
then the liquid solidify 's (Cause it changes from a liquid state to a solid)
