ASA (American Sociological Association) is a professional organization for sociologists that promotes the advancement of sociology as a scientific discipline and serves as a resource for professionals in the field. As such, ASA has established a set of guidelines for writing and formatting sociological research papers and essays that are known as the ASA style.

The ASA style is a widely used citation and formatting style in the field of sociology and social sciences. It is similar to the APA (American Psychological Association) style, but there are some important differences. One of the key differences is that ASA style requires the use of parenthetical citations in the text of the paper, rather than footnotes or endnotes. In addition, ASA style requires a specific format for the reference list at the end of the paper.

When writing a research paper or essay in ASA style, it is important to follow the guidelines for formatting and citation. This includes using appropriate margins, font, and font size, as well as properly citing sources in the text and in the reference list.

One of the key elements of ASA style is the use of parenthetical citations in the text of the paper. This means that when you refer to a source in your paper, you include the author's name and the year of publication in parentheses at the end of the sentence. For example, "According to Smith (2020), sociological research has shown that social media use has a significant impact on people's relationships and communication patterns."

Another important aspect of ASA style is the reference list at the end of the paper. This list should include all of the sources that you cited in the text of your paper, and should be organized alphabetically by author's last name. Each entry in the reference list should include the author's name, the year of publication, the title of the work, and the publication information.

Overall, ASA style is a useful tool for writers in the field of sociology and social sciences, as it helps to ensure that research papers and essays are properly formatted and that sources are properly cited. By following the guidelines for ASA style, writers can ensure that their work is professional and scholarly, and that it adheres to the standards of the discipline.

9 Latent Heat Examples in Daily Life

latent heat of milk

Some of these models have been based on thermodynamic principles, while others were strictly empirical. Water is added to the calorimeter until it is about 2-inches away from being completely full. Water has the greatest influence on the specific heat. Therefore, in a quantitative analysis of a thermodynamical system, specific latent heat is preferred over latent heat. . The cup was removed from the insulated container and placed on the platform balance.

As the pressure is reduced, the boiling point decreases, and the latent heat value increases. At atmospheric pressure, water boils at 100 ̊C and the latent heat of vaporisation is 2257 kJ kg-1. Heat exchangers are commonly used for the purposes of heating and cooling foods. Because it takes more energy to convert a substance from one physical state to another solid to liquid, or liquid to gas , those transitions require a larger amount of energy. Do you know why does a pressure cooker cooks faster than an ordinarily covered pot? Following the comparison of the calculated Lf from the experiment with the actual value Lf of milk, which is 2. Both sensible and latent heats are observed in many processes while transporting energy in nature.

Using the specific heat value of the unknown metal and its density, it was determined that the unknown metal was Tin. A schematic DSC thermogram showing an endothermal, first-order phase transition, for example, melting. DTA measures temperature of a sample and a reference as a function of temperature. Here, we will learn about latent heat, different types of latent heat along with the formula and dimension of latent heat. . This information is significant in proving that the mass of the object is not an impactful factor in the amount of heat given off or the duration of the combustion of the object.

At reduced pressures below atmospheric, water boils at lower temperatures as shown in Chapter 14 Fig. The decreasing trends of springiness and gumminess with an increase in TNP and porosity could be explained by stress—strain analysis. It is a method of cooking that works on moist heat. It keeps the head bobbing back and forth for a while, and as the water evaporates, latent heat of vaporization causes condensation of the vapors present in the head. Examples are The term was introduced around 1762 by latere to lie hidden.

During vaporization, the energy obviously no longer benefits the increase of the kinetic energy of the molecules, which would otherwise mean an increase in temperature see also article Figure: Vaporization of water in a pot on a hotplate During vaporization, the transferred energy leads to an increase in the broken by the added heat energy, thus allowing the transition to the gaseous state. . Conclusion: The data obtained from the experiment was able to give an approximate value for the latent heat of fusion for milk. If the amount of heat needed for a phase change is 300 kcal, calculate the latent heat of a 5 kg material. The freezing point of milk is of considerable interest, because it is also used to detect any dilution of the milk. The input energy required to change the state from liquid to vapor at constant temperature is called the latent heat of vaporization. The second error was the equipment used.

Thus, the Lf for the milk used in trial 1 would most likely have an Lf value that is different to the average of 2. This makes chocolate bars taste "cool". The evaluation of the experimental data shows that about 120 kJ of heat are necessary to vaporize 48 g of water. Add some more energy, and the molecule breaks down into ions and electrons, giving the plasma phase. Generally speaking, slow freezing—slow transport of latent heat—causes fewer nuclei to form per a given volume and time, which allows more space for each crystal to grow in and results in larger crystals. A condensing furnace comes with a second heat exchanger after the first. Fouling is a common occurrence in thermal operations and its impact on heat transfer can be determined with appropriate expressions.

Summary The heating has two effects. There is a growing interest in modeling the heat transfer during HP processing of food products by means of computational fluid dynamics CFD technology Ghani and Farid, 2007; Knoerzer and Chapman, 2011. This has important implications in unit operations which involve conduction of heat through food to remove water e. In this chapter, we will try to learn the thermal properties of milk and milk products. Experiments with Long exposure and lights-033 Analysis: From the concept of thermal equilibrium the latent heat of fusion for milk was calculated from the data obtained from the experiment. In order to make sure this error was minimised, it was decided that the group would choose one member to take all measurements with the thermometer to ensure consistency.

This allows furnaces that would normally extract 80 to 85% of the heat of combustion to reach efficiencies of 90 to 95%. From the above experiment, we can say that heating has two effects. The reason is that energy must be expended to change the state from solid to liquid or from liquid to gas. Milk has highest specific heat 0. Once all the water is turned into vapor, a further transfer of heat will simply increase the temperature again. At 20°C, a piece of metal has a density of 60g. Unfortunately the situation for foods is more complex.

Composition data for foods are readily available in the literature. Consequently, thermal conductivity of frozen foods will be three to four times higher than that of unfrozen foods. Unit operation of various dairy and food. On this basis, Lamb suggested the following equation to determine the latent heat value of food. . It contains 90% of water. From the trials, the most accurate trial presented the Lf of milk as 2.

One such way to correct this issue is to ensure all equipment was accurate and in perfect While the smallest percentage error was 0% 2. Loss of water might lead to the compression of muscle fibers and increase of the concentration of the interstitial fluid, and thus enhance the adhesive power and strength McDonald et al. The largest percentage error out of the three experiments was approximately. Later, when the ice is completely melted, a further increase in heat will raise the temperature again until it reaches 100 ºC. .
