Sensible heat is the heat required to raise the temperature of a substance.
When determining the heat of a vapor, moisture must be considered as it removes heat from the vapor (in order to heat the moisture [water vapor] to the ambient temperature). Dry steam has no moisture. Dry air has no moisture (a physical improbability).
Air normally has moisture determined as relative humidity. This humidity [water vapor] must be heated with the air. Then the moisture heat absorption must be subtracted from the whole to determine the heat absorption of the air without moisture, expressed as heat per unit per degree (often 0.24 btu per dry standard cubic foot per degree F for air). Any moisture in the air increases the heat necessary to raise the temperature by about 1 btu per pound of moisture per degree F. (0.004 btu per gram of moisture per degree F).
This increased heat requirement becomes more evident as air is compressed, and the moisture is removed by condensation.

How much heat does it take to raise the temperature of a substance one degree?
The amount of heat required is called the specific sensible heat for the substance. Sensible, in this context, means something which can be sensed. This is in contrast to latent heat which is used to change the phase of a substance without a change in temperature.
Sensible heat involves a change in a substance's?
Sensible heat refers to the heat that is exchanged by a body or thermodynamic system. It involves a change in a substance's temperature.
Where does the heat and moisture of hurricanes come from?
The heat and moisture comes from warm ocean water. The heat that warms the ocean water ultimately comes from the sun.
What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.
How does moisture evaporating from major bodies of water effect weather patterns?
the moisture provides heat to the oceans so without it, the water is cool and usually results in sea breeze, thus cooling the atmosphere
What is room sensible heat factor?
It is the ratio of room sensible heat to the total heat.
What is meant by sensible heat factor?
Sensible Heat Ratio - SHR - is defined as the sensible heat or cooling load divided by the total heat or cooling load.
What is the meaning of phosphorescent?
Shining with a phosphoric light; luminous without sensible heat., A phosphorescent substance.
Difference between sensible heat and latent heat?
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.

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. 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.
What is sensible heat?
Sensible heating is the process of changing the temperature of an object. The increase and removal of heat are considered sensible heating.
Why does a grill not conduct heat?
Grilling does not conduct heat because it is a known as dry heat cooking. It is where the heat goes to the food without having any moisture.
Sensible heat involves a change in a substance's?
Sensible heat refers to the heat that is exchanged by a body or thermodynamic system. It involves a change in a substance's temperature.
What is the best way to change the sensible heat level of the evaporator?
what is the best way to change the sensible heat level of the evaporator
What is released as sensible heat during the formation of clouds?
Latent heat.
Can sensible heat and latent heat transfers be read with a thermometer?
yes
