Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance . It could either be from a gas to a liquid or liquid to solid and vice versa. Latent heat is related to a heat property called enthalpy.
What do you mean by latent heat explain with example?
Latent heat of the solid means that amount of heat energy absorbed when 1 kg of a substance changes from solid to liquid at its melting point is called latent heat of fusion of the solid. example : Change if ice into water requires a certain heat level so, that it can broke its compactly arranged particles.
What is latent heat Short answer?
Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance . It could either be from a gas to a liquid or liquid to solid and vice versa. Latent heat is related to a heat property called enthalpy.
What is mean by latent?
: existing in hidden or dormant form : as. a : present or capable of living or developing in a host without producing visible symptoms of disease a latent virus a latent infection.
What is meant by latent heat How will the state?
Latent heat of a body is the amount of heat required to change the state of unit mass of the body from solid to liquid or from liquid to gas without any change in temperature .
Why it is called latent heat?
Latent heat, also called heat of transformation, is the heat given up or absorbed by a unit mass of a substance as it changes from a solid to a liquid, from a liquid to a gas, or the reverse of either of these changes. It is called latent because it is not associated with a change in temperature .
What are two types of latent heat?
Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling) . These names describe the direction of energy flow when changing from one phase to the next: from solid to liquid, and liquid to gas.
What are three types of latent heat?
- Latent Heat of Fusion,
- Latent Heat of Vaporization,
- Latent Heat of Sublimation.
How can you detect latent heat?
Measuring latent heat
Latent heat can be measured from a heating or cooling curve line graph . If a heater of known power is used, such as a 60 W immersion heater that provides 60 J/s, the temperature of a known mass of ice can be monitored each second. This will generate a graph that looks like this.
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.
What is an example of latent?
The definition of latent is something present but invisible or hidden. An example of latent is an ability to swim that will become clear with a first lesson . An example of latent is a psychological tendency that you are not fully aware of. An example of latent are fingerprints which cannot be seen.
What are latent skills?
Becoming a modern leader comes from tapping into and realizing latent skills — the majority of skills that you possess outside your default strengths that with focus and practice become new pillars of success .
What is a latent person?
present but not visible, apparent, or actualized ; existing as potential: latent ability. Pathology. (of an infectious agent or disease) remaining in an inactive or hidden phase; dormant. Psychology. existing in unconscious or dormant form but potentially able to achieve expression: a latent emotion.
What is meant by sensible heat?
When 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.
What is meant by latent heat of fusion?
The amount of heat required to convert one unit amount of substance from the solid phase to the liquid phase — leaving the temperature of the system unaltered — is known as the latent heat of fusion. ... It is also equal to the enthalpy difference between the solid and liquid phases, ΔH SL .
What is difference between temperature and heat?
Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).
