Latent heat has the ability to do something in a given time period. Take a water heated radiator, latent heat has the ability to make the radiator warm or hot according to the temprature of the water. It will continue to do this until the water stops flowing through the radiator and the radiator begins to cool.

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. 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.
No, latent heat can never be zero.Because latent heat is the hidden heat so there has to be heat more than zero.
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.

pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam.

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.
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 an object is hot, the temperature rises as heat is added. This increase in heat is called sensible heat. Solids can become liquids and liquids can become gases but changes like this require the addition or removal of heat. The heat that causes these changes is called latent heat.

what is latent heat
when a liquid evaporates,it gives its latent heat of vaporisation.if no heat is supplied from outside this results in cooling.
