How do you find the latent heat of a mixture?

How do you find the latent heat of a mixture?

Determination of Latent Heat of Steam by the Method of Mixture

1. Following are the steps to determine the latent heat of vaporization of water:
2. m1= mass of calorimeter and stirrer.
3. m2 = mass of calorimeter, stirrer and water.
4. mw = m1 – m2 = mass of water only.
5. m3 = mass of calorimeter, stirrer, water and steam.
6. m= m3 – m2 = mass of steam only.
7. sc = specific heat capacity of a calorimeter.

How specific latent heat of steam is experimentally found?

Setup for measurement of latent heat of vaporization – definition. The experimental set up helps us to send steam with a measured temperature into a calorimeter with known mass of water. The mass of the steam condensed is equal to the increase in the mass of water in the calorimeter after the steam is sent into it.

What is latent heat of fusion and vaporization?

The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization. …

What is latent heat of fusion state its units?

When a solid is converted into liquid at constant temperature (melting point of the substance) the amount of heat absorbed by it is called the latent heat of fusion. Heat is a form of energy . Hence , latent heat is expressed in units joule, erg, calorie or kilocalorie. Get Link in SMS to Download The Video.

What is meant by the specific latent heat of fusion?

The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. 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)

What are the SI units of latent heat?

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. uses the SI unit joule per kilogram [J/kg].

What happens to the heat supplied to the substance?

Heat supplied to a substance during its change of state is called latent heat. It is used up in increasing the potential energy of the molecules of the substance and in doing work against external pressure if there is an increase in volume. Hence there is no change of temperature.

Where is water used as a heat reservoir?

(ii) As heat reservoir – In cold countries, water is used as a reservoir for wine and juice to avoid their freezing. The reason is that water can provide more heat to the bottles due to its high specific heat capacity. Hence, they do not cool down further to freeze.

What happens inside the nucleus that causes the emission of beta particle?

What happens inside the nucleus that causes the emission of beta particle? This is because during beta emission a neutron gets converted into a proton and hence total number of protons and neutrons remains constant i.e., mass number remains.

What happens to the heat supplied to a substance when the heat supplied causes no change in the temperature of the substance define the phenomenon with the formula?

Question 55: What happens to the heat supplied to a substance when the heat supplied causes no change in the temperature of the substance? Answer: This heat supplied is used in the change of state. This heat is known as Latent heat.
