Difference Between Latent Heat and Sensible Heat | Definition, Different Types
The most common forms of latent heat are fusion and junkgenie.info Fusion is the passage of a body from solid state to liquid state. During. For example, in a cooling system condensation forms due to removal of latent heat, and the refrigerant (cooling liquid) changes temperature. What is the difference between SENSIBLE AND LATENT HEAT. Conversely, if you cool off some water vapor, it can condense into liquid.
Sensible heat is related to changes in temperature of a gas or object with no change in phase. Why do I care? Latent heat released during any kind of storm increases instability in the atmosphere potentially causing severe weather.
Sensible heat causes change in temperature due to contact with colder or warmer air of surfaces. I should already be familiar with: If a substance is changing from a solid to a liquid, for example, the substance needs to absorb energy from the surrounding environment in order to spread out the molecules into a larger, more fluid volume. If the substance is changing from something with lower density, like a gas, to a phase with higher density like a liquid, the substance gives off energy as the molecules come closer together and lose energy from motion and vibration.
For example, when water is boiled over a stove, energy is absorbed from the heating element and goes into expanding the water molecules into a gas, known as water vapor. When liquid water is put into ice cube trays and placed in the freezer, the water gives off energy as the water becomes solid ice.
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.
Comparison between Sensible Heat and Latent Heat
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.

- Difference Between Latent Heat and Sensible Heat
Clouds form when warm air rises and the water vapor it contains condenses onto particles called cloud condensation nuclei. 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.
Comparison between Sensible Heat and Latent Heat
When the phase of matter is changed, it either requires energy or releases energy in the form of heat. This exchanged energy is called latent heat.
The three main phases of matter are solid phase, liquid phase and gas phase. The value of latent heat varies with the nature of matter.
Given below are examples. When a liquid is converted into its solid phase, it is known as the latent heat of fusion. When a liquid is converted into its gaseous phase, it is known as the latent heat of vaporization. When a solid is converted into its gaseous phase, it is known as the latent heat of sublimation.
Phase Transition of Matter Latent heat is defined for a system with constant temperature.

Therefore, this term describes the change of phase regarding the internal energy of the system. 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.
