Processes such as melting, boiling, and sublimation absorb sensible heat. Sensible heat is the heat required to change the temperature of a substance without a change in phase. When a substance undergoes these processes, it absorbs energy to break intermolecular forces and change its state.

What is the opposite of latent heat?
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
How do you calculate sensible heat if you know cfm and temperature difference?
To calculate sensible heat, you can use the formula: Sensible Heat (BTU/hr) = 1.08 x CFM x Temperature Difference (°F). Just multiply the CFM value by 1.08 and then by the temperature difference in Fahrenheit to get the sensible heat in BTU per hour.
What is the two states of heat?
The two states of heat are latent heat and sensible heat. Latent heat is the heat absorbed or released during a change of phase, such as melting or boiling. Sensible heat is the heat exchange that causes a change in temperature without a change in phase.
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.
Will tin foil absorb heat?
Tin foil does not absorb heat, but it can reflect heat if it is shiny and smooth. This can help to trap heat in or keep heat out, depending on how it is used.
Do flowers absorb heat?
Flowers do not absorb heat directly as they do not have the metabolic processes to generate heat. However, they can be affected by heat from their surroundings, which can impact their growth and development.
Is it true that in order for water at 60 degrees Fahrenheit to boil it must absorb both sensible and latent heat?
Yes, for water at 60 degrees Fahrenheit to boil, it must first absorb sensible heat to reach its boiling point of 212 degrees Fahrenheit. Then it must absorb latent heat to undergo the phase change from liquid to gas. This process of absorbing both sensible and latent heat is necessary for the water to transition from a liquid state to a gaseous state.
Do clear liquids absorb heat?
Clear liquids, like water, have the ability to absorb and retain heat. When exposed to heat, clear liquids will increase in temperature as they absorb the thermal energy. This property is utilized in various applications such as cooling systems and heat transfer processes.
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 processes are endothermic?
Examples of endothermic processes include melting of ice, dissociation of ammonium nitrate, and baking soda reacting with vinegar. These processes absorb heat from the surroundings to proceed.
What is the opposite of latent heat?
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
Do plants give off heat as part of their natural processes?
No, plants do not give off heat as part of their natural processes. They primarily absorb sunlight for energy through photosynthesis and release oxygen as a byproduct.
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.
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
Is freezing Endo or Exo?
Endothermic reactions absorb heat from their surroundings and feel cold, whereas exothermic reactions release heat into their surroundings and can feel warm. The sensation of freezing is typically associated with endothermic processes because they absorb heat during the reaction.
Is melting an ice cube an example of endothermic processes?
No, melting an ice cube is an example of an exothermic process because it involves the absorption of heat from the surroundings to overcome the forces holding the ice molecules together. Endothermic processes absorb heat from the surroundings, while exothermic processes release heat.
