Let’s consider the following text as an example. A closing sentence can be safely omitted in short paragraphs dealing with rather simple and straight-forward ideas, but it is an essential element when discussing more complex topics. So don’t start with the details, start your paragraphs with the topic or main point and help your reader avoid the frustration!Īs the topic sentence is the optimal beginning of your paragraph, a closing sentence providing a brief summary or conclusion is the best way to wrap-up the contents of your paragraph and create a smooth transition to the next paragraph. ![]() Maybe you have read paragraphs like those before: when the paragraph finally comes to the point, you need to read it again to really understand it. If the topic you write about is complex (and I bet your research project is complex), this approach typically leads to a cognitive overload of your reader. On the other hand, if you omit the topic sentence and start out with details, your reader will need to keep everything in their mind until you finally provide the key to tie all those details together. Check out how it works with this article and its topic sentences. ![]() Moreover, the proper use of topic sentences allows the reader to gain an overview of the article content by just reading the first sentence of each paragraph. It gives the reader an idea of what the paragraph is going to be about - it provides context which enables the reader to easily follow the subsequent reasoning and understand the details even when they are complex. This topic sentence, the sentence containing the main point or introducing the topic of the paragraph, makes for the perfect beginning of your paragraph. If it is not possible to find an overarching theme for all the details contained in your paragraph, then you should either split the paragraph (if it deals with several different points) or think about what you want to say with that paragraph in the first place (if it seems like the paragraph is not making any point at all). To test whether a paragraph really contains a single topic is simple: try to express the topic of your paragraph in one sentence. A paragraph allows you to introduce, discuss, and conclude an idea in a “single package”, which makes the reader’s job as easy as it can get. The golden rule of writing great paragraphs is to discuss only one idea or topic per paragraph. But is this really a good criterion? If you have any doubts about how to best structure your scientific text in paragraphs, then this article is for you. How do you make paragraphs in your scientific texts? Do you proceed intuitively, as one researcher admitted to me recently? He reported to start a new paragraph simply when the current one gets “long enough”. If you feel like your manuscripts are hard to understand and lack a flow and logical structure, learning the art of paragraph writing might be just the solution you need. Carefully designed paragraphs are the key to well-structured and easy-to-read texts.

![]() The particles usually less than 1 micrometer in size, and they suspended in a liquid or gas. The Brownian motion most easily observed in a suspension of small particles in a fluid. The Brownian motion named after the botanist Robert Brown, who first observed the phenomenon in 1828. The particles constantly buffeted by the surrounding fluid molecules, and this movement results in a chaotic jittering motion. The Brownian motion describes the random movement of particles suspended in a fluid. The tiny particles constantly buffeted by the molecules around them, and this motion causes them to move around chaotically. The Brownian Movement is the movement of tiny particles (such as atoms or molecules) in a liquid or gas, caused by the random motion of the molecules in the liquid or gas. ![]() What is the Brownian Movement in Chemistry? This movement is caused by the thermal energy of the particles. The particles are constantly moving around and bouncing off of each other. Motion of the pollen grain in water, movement of dust particles in a room, diffusion of pollutants in air are the Brownian motion examples.The Brownian Movement is the random movement of particles in a fluid.Brownian motion of the particles in a fluid depends on the size of the particle, density, viscosity and temperature of the fluid.Brownian motion can be calculated by parameter diffusion constant, which is given by.The unbalanced random force due to molecules of the fluid on the suspended particles causes it to move in an irregular manner.It was discovered by Robert Brown in 1827.The random or irregular motion of particles suspended in a fluid is called Brownian motion.Size of the particles: Brownian motion of the particles of bigger size is less to that of the particles of smaller size.Density of the fluid: Brownian motion of the particles increases with the decrease in density of the fluid and vice versa.Viscosity of the fluid: Brownian motion of the particles decreases with the increase in viscosity of the fluid in which particles are suspended and vice versa.Temperature of the fluid: Brownian motion of a particle increases with the increase in temperature and decreases with the decrease in temperature of the fluid.These are the factors which affects Brownian motion of the particles in a fluid: Therefore, temperature of the surrounding is given by Radius of the Brownian particle, r = 1.2 x 10 -10 m ![]() Given, Fluid viscosity, ɳ = 18 x 10 -6 Psĭiffusion constant, D = 0.5 x 10 -6 m 2 /s k B = 1.38 x 10 -23 JK -1, is Boltzmann constant and,īut, mobility of the particle of radius r in a fluid of coefficient of viscosity ɳ, is given byĪlso, Boltzmann constant, k B= \(\frac\).µ = mobility of the particles in the fluid,.It is also known as Brown noise or Red noise.īrownian motion of the particles suspended in a fluid can be calculated by a parameter known as the Diffusion constant ( D) and it is given by A low frequency sound is produced during the brownian motion of the particles, which is known as Brownian noise.Hence, the particles are subjected to an unbalanced force at each instant, causing them to move randomly.For the smaller particles, the number of molecules striking the various sides of the particle at any instant may not be equal.If the size of the suspended particles are sufficiently large then, an equal number of molecules strike the particles from each side at each instant.The suspended particles are extremely large in size as compared to the molecules of the fluids and these particles are continuously bombarded with the molecules of the fluids from all sides.Brownian motion can be defined as the irregular or uncontrolled movement of particles in fluid because of their constant collision with other fast moving molecules. The variability in the Atlantic Coast distribution appears to be lower than in the California distribution. The Atlantic Coast distribution's median is lower than the California distribution's median. The Atlantic distribution appears to be devoid of outliers, whereas the California distribution appears to contain one. The distribution on the Atlantic Coast is skewed to the right, whereas the distribution in California is roughly symmetric. The Atlantic Coast distribution appears to have less variability than the California distribution, with data values ranging from 0.3 cm3 to 10.5 cm3, whereas data values for California range from 0.4 cm3 to 171 cm3. The median of the Atlantic Coast distribution (1.7 cm3) appears to be less than that of the California distribution (41 cm3). The median is the value in the middle of the sorted data set.
