Sensible heat refers to heat you can feel, or sense. This is any heat which can be measured on a thermometer, whether it’s heat from the sun shining on a sunny day, or the flame from a candle. When an object is heated, the object’s increase in temperature is sensible heat. Similarly, when heat is removed from an object and its temperature ...
Both sensible and latent heats are observed in many processes while transporting energy in nature. Latent heat is associated with changes of state, measured at constant temperature, especially the phase changes of atmospheric water vapor , mostly vaporization and condensation , whereas sensible heat directly affects the temperature of the atmosphere.
Diffusion constants [m 2 /s] for several gases in water. Great Sensible Heat Factor - GSHF The Great Sensible Heat Factor is the ratio sensible to total heat in a cooling coil. Heat Capacity The amount of heat required to change the temperature of a substance by one degree. Heating Water by Injecting Steam Water can be heated by injecting steam.
Sensible heat is literally the heat that can be felt. It is the energy moving from one system to another that changes the temperature rather than changing its phase. For example, it warms water rather than melting ice. In other words, it is the heat that can be felt standing near a fire, or standing outside on a [[sunny day.

Heat that results in a temperature change is said to be "sensible" (although this term is falling out of favor). This is because it can be "sensed" I assume. 1781 Wilcke comes up with the concept of specific heats. 1819 Objects have a heat capacity, while materials have a specific heat capacity (often just called specific heat) was first defined by...
A calorie is the energy needed to raise the temperature of one gram of water by one celsius degree. This turns out to be a terrible definition as the heat required to raise the temperature of any substance varies with temperature itself. The specific heat of liquid water varies with temperature. Thus, there are at least five different units that ar...
From the "mechanical equivalent of heat" to the "specific heat capacity of water" A British thermal unit (Btu or BTU and also known as a heat unit in the United States) is the energy needed to raise the temperature of one pound of water by one fahrenheit degree. Like the calorie, there are several different types of Btu, each based on a different i...
Mass specific heats vary significantly with material, but molar specific heats are rather similar. This empirical relationship is known as the Law of Dulong and Petit (1819) after its co discoverers Pierre Louis Dulong (1785–1838) and Aléxis Thérèse Petit(1791–1820) of France. (An interesting aside: Dulong accidentally lost an eye when he discovere...
Nov 6, 2015 · Heat added from point 3 to point 4 is sensible heat; when point 4 is reached, 180 Btu of heat will have been added from point 3. The water has been heated from 32°F to 212°F, which is a 180°F rise. Referring back to the definition of the Btu, you will see that it takes 1 Btu of heat energy to raise the temperature of 1 lb of water 1°F.
