Does a liquid give off energy or absorb energy when it turns into a gas?
It absorbs energy, the latent heat of vaporisation. This can be stated as so many Joules or calories per kilogram. When the gas condenses heat is given out.
Latent heat energy levels?
The latent heat energy levels refers to the heat absorbed during a change phase at a constant pressure and temperature.
What is sensible and latent heat?
Sensible heat is potential energy in the form of thermal energy or heat. The thermal body must have a temperature higher than its surroundings. The thermal energy can be transported via conduction, convection, radiation or by a combination thereof. The quantity or magnitude of sensible heat is the product of the body's mass, its specific heat capacity and its temperature above a reference temperature. In many cases the reference temperature is inferred from common knowledge, i.e. "room temperature". latent heat is the amount of energy in the form of heat released or absorbed by a substance during a change of phase (i.e. solid, liquid, or gas) Two latent heats (or enthalpies) are typically described: latent heat of fusion (melting), and latent heat of vaporization (boiling). The names describe the direction of heat flow from one phase to the next: solid → liquid → gas. The change is endothermic, i.e. the system absorbs energy, when the change is from solid to liquid to gas. It is exothermic (the process releases energy) when it is in the opposite direction
What information does the latent heat of fusion give?
latent heat of fusion tells us about the amount of energy that must be taken off from water at 00C to fuse it into ice at 00C . Actually this in this phase temperature remains constant and this energy is (either latent heat of fusion or latent heat of vaporization is the potential energy which is possessed by the states by their virtue.
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 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.
When water freezes it absorbs what?
Nothing, it gives off latent heat of freezing
When water evaporate it absorbs heat energy?
Evaporation is an endothermic process.
Does a liquid give off energy or absorb energy when it turns into a gas?
It absorbs energy, the latent heat of vaporisation. This can be stated as so many Joules or calories per kilogram. When the gas condenses heat is given out.
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 do endothermic reactions absorb heat?
a process or reaction in which the system absorbs energy from the surroundings in the form of heat.
How do you define latent heat and What is its relationship to potential energy?
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.
What is a reaction that absorbs energy?
The type of reaction that absorbs energy is endothermic. This process takes the energy from its surroundings, absorbs it, and creates heat.
Latent heat energy levels?
The latent heat energy levels refers to the heat absorbed during a change phase at a constant pressure and temperature.

Why is latent heat of vapourisation higher than latent heat of fusion?
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.
Why do you feel cool after you perspire?
Because as water evaporates it absorbs latent heat of vaporisation
