The latent heat of vaporization measures the amount of energy required to convert a unit mass of a substance from a liquid to a gas at a constant temperature and pressure. This energy is necessary to overcome the intermolecular forces holding the liquid molecules together, allowing them to escape into the gaseous phase. It is a crucial property in processes such as boiling and evaporation and plays a significant role in climate and weather patterns.
The energy required to boil a substance
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.
the answer is latent Latent heat is correct, but specifically the latent heat of evaporation of (whatever is evaporated, in this case water) water. When the evaporated water condenses, it releases this latent heat as it precipitates, which is why it tends to feel warmer during rainstorms (unless the water is running down your neck in which case it feels horrible).
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.
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
The energy required to boil a substance
No, latent heat cannot be measured directly with a thermometer. Latent heat is the energy absorbed or released during a phase change (e.g. melting, boiling) without a change in temperature. The amount of latent heat can be calculated using specific equations and constants for each substance.
The symbol for latent heat is ( L ).
yes
Latent heat of evaporation of water to steam is 2270 KJ/Kg
Latent
A thermometer measures temperature by detecting the average kinetic energy of the particles in a substance, rather than the energy involved in phase changes, such as latent heat. Latent heat is the energy absorbed or released during a phase change, like melting or boiling, and does not directly affect the average kinetic energy of the particles that the thermometer detects.
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
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.
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.
dimensions are just the measurements of Length, width and Height so i think to measure the dimension you just measure the object and record the distance
Latent heat is the heat required to achieve a change of phase - for example, to melt ice and convert it to water. As to the relationship with potential energy, latent heat IS a type of potential energy.
