Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

Cloud Formation Cloud A cloud is a visible mass of condensation droplets. Water moves into the atmosphere through the process of evaporation and transpiration. Water vapors join the dust particles in the atmosphere to form clouds.  Finally, water returns to Earth as precipitation in the form of rain, snow, and hail. Clouds cannot be formed…

Both Diamond and Graphite are different forms of carbon, known as allotropic forms. Despite sharing the same element, they display contrasting properties. Diamond is exceptional in conducting heat but lacks conductivity in electricity, whereas graphite struggles with thermal conduction but excels in electrical conduction. This variation in properties is a result of the distinct arrangement…

Jupiter is a gas giant. This means that it has a huge atmosphere, a liquid mantle, and a liquid / solid core, with no definite boundary between the layers. The core officiate is probably composed of liquid rock, at a temperature as high as 24,000 K (43,000 OF). The core is small relative to the…

“As we shall see, it is generally believed that the phenomenon of superfluidity is directly connected with the fact that the atoms of helium-4 obey Bose statistics, and that the lambda-transition is due to the onset of the peculiar phenomenon called Bose condensation” (Leggett, 1989). This is the phenomenon wherein the bosons (a type of…

Introduction: To acquire the consistent results in biomedical research, familial stableness is indispensable and it is achieved via cryopreservation technique. Technique of cryopreservation involves the saving of feasible cells, populating tissues, gametes, embryos, variety meats and besides some beings on chilling at low sub-zero temperatures, characteristically at -196A°C for a drawn-out clip to implement the…

That release ultra-violet radiation, x-rays and gammy rays. It’s an enormous explosion of hydrogen and helium above the sun surface. It’s a sudden rapid and intense variation in brightness that happens every eleven yearsB. They usually last an average of 20 minutes and are a remarkable phenomenon. Imagine gigantic blobs of materials held together by…

According to the kinetic molecular theory, gas particles are constantly in motion just like other forms of matter. However, their movement is distinct in that it is characterized by random translation. In solids, the particles primarily undergo vibrational motion. In liquids, they mainly vibrate and rotate, and also experience some translational motion. Gas particles move…
