What Is The Example Of Latent Heat?

What are the three sources of heat?

In the end, if you’re wondering where the heat in your home comes from, it’s almost certainly one of the three main sources: combustion, electric resistance, or the outdoor air, ground, or water..

What are the five sources of heat?

Heating Energy SourcesGas Fired Water Heater. Here at Radiantec we often recommend the use of domestic water heaters instead of expensive boilers. … Oil Fired Boilers or Water Heaters. Oil can be less expensive than gas in some locations at this time. … Wood or Coal Heaters. … Solar Collectors. … Radiant Retrofit. … Electric Heat. … Geothermal.

Can you measure latent heat?

The specific latent heat (L) of a material… is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. is defined through the formula Q = mL. is often just called the “latent heat” of the material.

What is Latent Heat Class 9?

The latent heat of fusion or melting of solid is the quantity of heat in joules required to convert 1 kg of solid to liquid,without any change in temperature. … The heat which is going into ice but not increasing its temperature,is the energy required to change the state of ice from solid to liquid.

What is sublimation class 9th?

Class 9 Chemistry Matter In Our Surroundings. Sublimation. Sublimation. The phenomenon of change of solid directly to gas or conversion of gas directly to liquid without changing into liquid state is called sublimation. For instance, camphor also called capoor when kept for a long time vanishes.

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.

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.

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.

What is latent heat of fusion?

The enthalpy of fusion of a substance, also known as (latent) heat of fusion is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

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 are the examples of heat?

Everyday Examples of Heat EnergyThe biggest example of heat energy in our solar system is the sun itself. … When the burner of a stovetop is very hot, it is a source of heat energy. … Automobile fuels such as gasoline are sources of heat energy, as is the hot engine of a racecar or a school bus.More items…

What are the applications 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 are 4 examples of radiation?

Radiation Examplesultraviolet light from the sun.heat from a stove burner.visible light from a candle.x-rays from an x-ray machine.alpha particles emitted from the radioactive decay of uranium.sound waves from your stereo.microwaves from a microwave oven.electromagnetic radiation from your cell phone.More items…•

What is the difference between latent heat and specific latent heat?

Specific heat: = energy required to change a unit mass of a material by 1°C. Units: energy per unit mass per degree. Latent heat = energy required to change the state (gas, liquid, solid) of a unit mass of material. Units: energy per unit mass.

What is Latent Heat describe its type with example?

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).

How do you describe 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.

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).

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 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.
