What Do You Understand By The Term Latent Heat What Are The Two Types Of Latent Heat?

What do you mean by the term latent?


present but not visible, apparent, or actualized; existing as potential: latent ability.


(of an infectious agent or disease) remaining in an inactive or hidden phase; dormant.

existing in unconscious or dormant form but potentially able to achieve expression: a latent emotion..

What is the synonym of latent?

dormant, quiescent, inactive, untapped, unused. undiscovered, hidden, unrevealed, unexpressed, concealed, unapparent, indiscernible, imperceptible, invisible, inert, covert, unseen, veiled, masked, lurking, undeveloped, unrealized, unfulfilled, potential, not activated, inoperative, in abeyance, suppressed, repressed.

What is difference between sensible heat and latent heat?

Latent heat is related to changes in phase between liquids, gases, and solids. Sensible heat is related to changes in temperature of a gas or object with no change in phase.

How do you get latent heat?

Latent Heat Of Fusion FormulaL = specific latent heat of fusion of substance.The total amount of heat absorbed or liberated by the material is.Let c be the specific heat of the metal.Heat gained by the metal.Q = 60 × c × (100 – 20)Q = 60 × c × 80 cal.Heat given is equal to Heat taken.0.5 × 540 = 60 × c ×80.

Can you feel latent heat?

If it condenses on its own, it will give off (sensible) heat and get warmer. Therefore sensible heat can be felt while latent heat is the type of heat that cannot be felt.

Why is latent heat of vaporization important?

Closely related to water’s unusually high heat capacity are its high latent heat of melting and latent heat of vaporization. … All the heat energy is being used to break all of the bonds (e.g. between polar water molecules) required to complete the change of state.

What is Latent Heat Class 9?

The heat energy which has to be supplied to change the state of a substance is called latent heat. Latent heat does not raise the temperature.

What is latent heat and its types?

Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling).

What is Class 9 boiling point?

NCERT Class 9 Science Lab Manual – Melting Point of Ice and Boiling Point of Water. … Boiling Point: The temperature at which the liquid boils and changes into gaseous state at the atmospheric pressure is called boiling point. For example, water boils at 100°C to form water vapour (at 76 cm pressure).

What is latent heat of condensation?

Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. An identical amount of calories (about 600 cal/g) is released in this process as was needed in the evaporation process.

What are latent abilities?

Latent abilities are additional abilities a unit can learn. To unlock and awaken these abilities, go to “Units” menu from home screen, click on “Awaken Abilities” button, then select “Latent Abilities”.

What are the application of latent heat?

Answer. The specific latent heat of vaporisation for water is large. Plates filled with food are able to absorb heat from the hot steam. The condensation of steam at the base of the plate releases a large quantity of heat and thus enables food such as cakes,fish, eggs and others to be steamed.

What do you understand by latent heat?

Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. … The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state.

What is Latent Heat Short answer?

The heat energy which has to be supplied to change the state of a substance is called its latent heat. Latent heat does not increase the kinetic energy of the particles of the substance, so the temperature of a substance does not rise during the change of state. …

What does latent effect mean?

latent, dormant, quiescent, potential mean not now showing signs of activity or existence. latent applies to a power or quality that has not yet come forth but may emerge and develop. a latent desire for success dormant suggests the inactivity of something (such as a feeling or power) as though sleeping.

What is the difference between heat and latent heat?

Specific heat is the amount of heat required to raise the temperature of a substance a certain amount. Latent heat is the amount of heat released during a change of state, i.e. the boiling of water or the melting of ice.

Why is latent heat important?

Latent heat is an important source of energy in the development of thunderstorms and hurricanes. Water vapor strongly absorbs infrared radiation, making it an important gas in the Earth’s heat-energy balance. In fact water vapor is the largest contributor to the greenhouse effect on Earth.
