Sensible Heat, Latent Heat and Radiation | The Science of Doom
Heat required to raise the temperature of water(say) is sensible heat and the What is the difference between evaporation and latent heat of vapourisation?. When water evaporates from liquid to gas, it gets energy from its surrounding. When water vapours change back from gas to a liquid, the latent heat is released. The most common forms of latent heat are fusion and gtfd.info Fusion is the passage of a body from solid state to liquid state. During.
It would be impolite.
Comparison between Sensible Heat and Latent Heat
The usual approach to teaching it starts with the shell model as the basic mechanism, and then tries to introduce convection as a minor modification to it.
This I believe to be wrong.

The effects of convection so dominate the result that it is in effect a completely different mechanism, and the intuition developed for the shell model is just misleading. But it persists, nevertheless. In a convective atmosphere, the surface temperature is controlled by the incoming energy, the average altitude of emission direct to space, and the lapse rate between that altitude and the surface. The atmosphere at the average emission altitude settles at the effective radiative temperature as any radiating body in a vacuum doesand then as air descends to the surface from that altitude driven by convection it is compressed by rising air pressure, and the compression increases its temperature.
The higher the altitude it descends from, the warmer the surface gets.
What is the difference between sensible and latent heat?
So in Atlanta the average altitude of emission to space is a bit higher than it is in Phoenix due to the extra H2O in the air, so air descending from this altitude has further to go and is compressed more. This energy is removed by the freezer system to keep the freezer cold.
Water vapor is a greenhouse gas located in the atmosphere and a very important component for cloud formation. If the air is dry, or unsaturated, clouds are not likely to form because there is minimal water vapor in the air.
If the air is moist, or saturated, the water vapor will condense to form clouds. When these gas molecules condense into liquid drops, latent heat is released into the atmosphere which warms the air surrounding the molecule.
This helps to add instability in the atmosphere and this warm air surrounding the molecule will want to rise. Warm air is less dense than cold air because molecules in warm air move around much faster and move further apart. Latent Heat in Thunderstorms and Hurricanes Latent heat plays a very important role in thunderstorms and hurricanes. Clouds form when warm air rises and the water vapor it contains condenses onto particles called cloud condensation nuclei.GEOG 141 SU17 (Video 09) Latent and Sensible Heat
At that point the air becomes saturated. When this air first begins to rise, the water vapor is in the gaseous phase. When the water vapor condenses to form clouds, it releases latent heat into the atmosphere.
The latent heat then warms the surrounding air around the new cloud droplet causing instability. The warm air around the cloud droplet will now want to rise and condense.

This increases the cloud height and depending on how unstable the atmosphere is, thunderstorms could form from these growing clouds. Latent heat is the work done in a system in order to hold the atoms or molecules of matter in the same phase.
What is Sensible Heat Sensible heat is the energy required to change the temperature of a substance with no phase change. In other words, sensible heat is the heat that can be felt. It is a type of energy that is either absorbed or released by a system. The changes in the temperature of systems cause changes in the sensible heat.
Unlike in latent heat, there is no change in phase of matter in the system when considering the sensible heat. It only describes the change in the temperature. Air conditioners work with the help of sensible heat For example, boiled water feels warmer than cold water.
This difference can be observed due to the sensible heat. In air conditioners, the cooling liquid or the refrigerant changes its temperature according to the sensible heat. Latent heat is the amount of energy that is either absorbed or released during a phase transition at a constant temperature.
Sensible heat is the energy required to change the temperature of a substance with no phase change.
