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.
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.
What is the difference between sensible heat gain and latent heat gain?
When an object is hot, the temperature rises as heat is added. This increase in heat is called sensible heat. Solids can become liquids and liquids can become gases but changes like this require the addition or removal of heat. The heat that causes these changes is called latent heat.
How would you calculate how much heat energy is required to raise the temperature of coal?
The same as you would calculate for any other substance. You have to multiply all of the following: • The desired temperature difference. • The mass of the sample. • The specific heat, in this case, of coal.
Is energy only transferred by heating if there is no temperature difference?
Heat can only be transferred if there IS a temperature difference. (If two objects have the same temperature, nothing will happen).

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 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 are the factors considered for heat load calculation?
Which of the following variables are used to calculate the sensible heat load of a product? Group of answer choices Respiration heat, specific heat, and temperature change. Latent heat, product weight, and temperature change. Latent heat, product weight, and respiration heat. Product weight, specific heat, and temperature change.

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.
What does temperature indicate?
The hotness or coolness of a body in regards to its sensible heat and is measured by a thermometer.
Is energy only transferred by heating if there is no temperature difference?
Heat can only be transferred if there IS a temperature difference. (If two objects have the same temperature, nothing will happen).
What is the difference beween heat energy and temperature?
Heat energy is "energy" and temperature is not "energy".
Does heat is NOT related to temperature differences?
Heat is the amount of energy transferred between objects where a difference in temperature is present. So in that sense, heat is related to temperature differences, but is not the same. The temperature difference is caused by the difference in the avg. speed of particles between the two objects.
