more thermal energy tend to go upwards and I assumed that the heat would make the gas particles inside the bottle expand and inflate the glove when there is no more space in the bottle My second hypothesis was also correct. I had a hypothesis of the glove deflating when the flask was put in ice because I knew that when gasses were cooled, the particles would start attracting each other more. When the gas particles that were in the glove start contracting, they would end up leaving the glove and…

The atom is the smallest unit of matter. The name “atom” comes from the Greek word atomos, which means “uncuttable.” Atomic theory states that all matter is made up of these small particles, and that these atoms, and the matter made from them, cannot be created nor destroyed, merely reshaped and reformed. Modern chemistry unofficially began in the eighteenth century. French scientist Antoine Lavoisier discovered the law of the conservation of mass c. 1785. This law states that “The total mass…

rotation in later modules. Momentum We define the linear momentum (p) of a particle of mass m travelling at a velocity v as: p ⃗ = mv ⃗ Momentum is a vector quantity, and its unit is kg-m/s. A particle either at rest or in constant velocity motion, will maintain a constant momentum. But if the particle is at rest or in constant velocity motion, there are no forces acting on it (Newton’s 1st law). When a force acts on the particle, its momentum will change over…

factors for sodium laurly sulphate dispersion. 1.2 Solution to the question: Introduction of colloids: Colloids are homogeneous non-crystalline substances. Here one substance is divide into more minute particles called colloidal particles and then it dispersed through a second particle. It includes emulsions, gel, sol. Colloids helpful for arising the problems in the preparation and dispersion of emulsions, suspensions, ointments, powders and other compresses dosage forms. In this the…

is divided into two types: crystalline solid is a solid that is made up of crystals and its particles are arranged in a regular pattern. When a crystalline solid is heated, it melts at a specific temperature. The second type is the amorphous solid, the particles aren`t arranged in a regular pattern. Different of a crystalline solid, the amorphous solid doesn`t melt…

a) Explain 2 key ideas in quantum mechanics. Two of the key ideas involved in quantum mechanics are wave particle duality and the Observer effect. These two ideas have changed the way that scientists think about the world. Firstly, wave particle duality is the fact that every elementary particle exhibits the properties of both particles and waves. This idea started with Thomas Young’s 1803 double-slit experiment. With a ripple tank he showed how water waves interfere with each other, and then…

effect of the intra-particle diffusion is examined by means of effective mass transfer coefficient. It can be obtained by similarity with heat transfer by conduction. Finally, the criterion for choosing the optimum switching time is set. 4.1. Fluidized Bed Model 4.1.1. Model Assumptions 1- The bed is perfectly mixed hence; all particles have the same temperature and moisture content at any given time. Air temperature and humidity changes are functions of time. 2- Intra-particle diffusion…

Neutrinos are one of the most abundant particles in the universe second only to photons, yet they are one of the most elusive particles known to man. The neutrino is essentially a near massless subatomic particle possessing a neutral charge. Neutrinos scarcely interact with normal matter as a consequence of having a neutral charge and a mass of almost zero. There are three flavors of neutrinos: electron, tau, and muon; many neutrinos oscillate between these flavors. Neutrinos can be produced in…

properties of fundamental particles that we are not able to observe with today’s technology. EPR argument also mentions an important topic in the discussion of action at a distance “element of reality” (1935). This states that if an observable property of a system, then it must correspond with an element of reality. In addition to this, EPR offered a proof that states the existence of two things that cannot coexist. One of them is that there are hidden variables present or particle attributes,…
