joules

## What is latent heat of vaporization?

**Latent heat of vaporization** is a physical property of a substance. It is defined as the **heat** required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg. … The **heat of vaporization** of water is about 2,260 kJ/kg, which is equal to 40.

## Is latent heat of fusion?

Overview. The ‘**enthalpy’ of fusion** is a **latent heat**, because during melting the **heat** energy needed to change the substance from solid to liquid at atmospheric pressure **is latent heat of fusion**, as the temperature remains constant during the process. … The liquid phase has a higher internal energy than the solid phase.

## What are three types of latent heat?

**There are three different types of latent heats,**

**Latent Heat**of Fusion,**Latent Heat**of Vaporization,**Latent Heat**of Sublimation.

## What is another name of latent heat?

Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-**temperature** process — usually a first-order phase transition.

## What is Latent Heat Class 9?

The term latent heat of vaporisation can be defined as the amount of heat needed for the conversion of 1kg of liquid at its **boiling** point to **gas** at same **temperature**. It differs among different liquids. Particles of water vapour at 100oC (373K) have more energy than liquid water at same **temperature**.

## How do you calculate latent heat?

**Latent heat calculation** The specific **latent heat** is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J ./span>

## What is specific latent heat?

**Specific latent heat** is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. … **latent heat** of vaporisation – the amount of energy needed to boil or condense the material at its boiling point.

## What are the two types of specific latent heat?

**Each substance has two specific latent heats:**

- latent heat of fusion (the amount of energy needed to freeze or melt the substance at its
**melting**point) - latent heat of vaporisation (the amount of energy needed to evaporate or condense the substance at its
**boiling**point)

## What is specific latent heat of fusion?

**Specific latent heat of fusion**, lf, of a substance is defined as the amount of **heat** required to change a unit mass of the substance from solid to liquid state, without any change in the temperature./span>

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

Hi Shrawani **Latent heat capacity** is the **heat** required by a substance without the change in temperature. **Specific heat capacity** is the **heat** required by a substance of unit mass to change the temperature by 1 degree C./span>

## How do you calculate latent heat of fusion?

Eh means energy, equals m for mass, times l. l is the **specific latent heat of fusion** for that material. So the **formula** tells us how much **heat** energy is needed to go into a material to change it from a solid to a melted liquid. If you apply **heat** to ice, it will melt.

## What is the latent heat of fusion of ice?

The value of **latent heat of fusion of ice** is 80 cal/g.

## What is CP of water?

The **specific heat capacity** often varies with temperature, and is different for each state of matter. Liquid **water** has one of the highest specific heats among common substances, about 4182 J/(K kg) at 20 °C; but that of ice just below 0 °C is only 2093 J/(K kg).

## What is Q MCP ∆ T?

**Q** = **mc∆T**. **Q** = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) **∆** is a symbol meaning “the change in”

## What is CP and CV?

So, **Cp** represents the molar heat capacity, C when pressure is constant. … In other words, **Cv** is the heat energy transfer between a system and its surrounding without any change in the volume of that system. **Cv** represents the molar heat capacity C when volume is constant.

## Is CP a CV?

**Cp** is greater than the molar specific heat at constant volume **Cv** because energy must now be supplied not only to raise the temperature of the gas but also for the gas to do work. … More heat would be required at constant pressure to cause the same temperature rise and **Cp** will be greater than **Cv**.

## What is CV for ideal gas?

The molar specific heat capacity of a **gas** at constant volume (Cv) is the amount of heat required to raise the temperature of 1 mol of the **gas** by 1 °C at the constant volume. Its value for monatomic **ideal gas** is 3R/2 and the value for diatomic **ideal gas** is 5R/2./span>

## What is CP CV ratio?

**Cp**/**Cv ratio** is defined as the **ratio** of two specific heat capacities. (i.e.) Heat Capacity **ratio** = **Cp**/**Cv** = Heat capacity at constant pressure/ Heat capacity at constant volume.

## What is K in specific heat?

The **specific heat** ratio of a gas (symbolized as gamma “γ” but also known as “**k**”) is commonly defined as the ratio of the **specific heat** of the gas at a constant pressure to its **specific heat** at a constant volume (see Equation 1).

## What is r in thermodynamics?

The ideal gas law is: pV = nRT, where n is the number of moles, and **R** is universal gas constant. The value of **R** depends on the units involved, but is usually stated with S.I. units as: **R** = 8.

## What is Gamma for CO2?

. For linear polyatomic gases (such as **CO2** or N2O ): γ≈1.
