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.
When would you see a change in behavior resulting from latent learning?

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.
Why is water an excellent material to use in the calorimeter?
because water has a very high specific heat capacity compared to most liquids
What materials have high latent heat capacity?
water
What late heat mean in HVAC?
All pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat. Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat. Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
How much heat can a central air conditioner remove?
It`s rated capacity in sensible and latent heat.
Difference between latent heat from sensible heat?
Two forms of heat are relevant in air conditioning:1. Sensible Heat2. Latent HeatSensible heatWhen an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.Latent heatAll pure substances in nature are able to change their state.

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.
What does 2.5 ton ac mean?
Cooling capacity of 30,000 btu per hour. That is the nominal total of both sensible and latent heat.
What is the difference of heat capacity and latent heat?
Specific heat capacity (equation Q=mc��T) is the measure of the energy required in Joules to raise 1kg of a substance by 1.0 K (numerically equivalent to 1 C)Whereas, specific latent heat (equation Q=mL) is the amount of energy needed to change to the state of a substance either from solid to liquid, liquid to gas without changing its temperature.
