Everything has matter. Matter makes up everything in the universe. Matter is anything that has volume or mass. I will be discussing the details of matter and other topics of science. All matter has all four general properties. They are mass‚ weight‚ volume‚ and density. The most important property of matter is mass. Mass is how much stuff‚ or matter‚ there is in any given object. Mass is the reason an object has‚ the second property‚ weight. When gravity pulls on an object it forms the weight. Weight

Energetics Practical 2: To Determine the Enthalpy Change of a Reaction Background Calcium Carbonate‚ CaCO₃‚ decomposes with heat to form CaO and CO₂. The objective of this practical was to determine the enthalpy change for this reaction by using an indirect method based upon the foundation of Hess’ Law. Both calcium oxide and calcium carbonate react readily with 2 mol/dm3. The reaction can be demonstrated as so: CaCO₃ (s) -> CaO(s) + CO₂ (g) Results: Raw Data Calcium Carbonate Mass of CaCO₃

Loft insulation Loft insulation is needed to save heat energy and contain it within the building. It reduces heat because hot air is lighter than cool air therefore hot air rises. Therefore the hot air that rises will stay at the top. Meanwhile the air below begins to gain heat and in turn rises while the hot air above loses heat and falls. This cycle is called convection. Loft insulation acts like a blanket‚ helping prevent heat escaping through the roof. Insulating your home isn’t a one

effect also contributes to the induced Polarization. If the dielectric permittivity of a material is very high‚ it usually implies that its structure allows for a mode of ionic displacements‚ which is very sensitive to external poling perturbations. BaxSr1-xTiO3 is a classical material used in microwave technology due to its high dielectric permittivity and appreciable dielectric nonlinearity. In this material‚ one of the polar optical phonon modes is responsible for its enhanced dielectricof

COULOMB’S LAW INTRODUCTION The magnitude of the force of attraction or repulsion between two electric charges at rest was studied by Charles Coulomb. He formulated a law‚ known as "COULOMB’S LAW". STATEMENT According to Coulomb’s law: The electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of charges. The electrostatic force of attraction or repulsion between two point charges is inversely proportional to the square of

Altering the Time in Which Spaghetti is Hydrated in Boiling Water and Observing the Mass Increase Introduction Mass is defined as a body with a particular amount of matter contained within it. The mass of a particular object is always stationary‚ but due to the gravitational pull on different surfaces‚ the weight of an object may change. In this investigation‚ I will be discussing and observing the mass increase of raw spaghetti when spaghetti is hydrated in boiling water. In each trial‚ the

Numerical Simulation of Marangoni-Driven Boundary Layer Flow Over a Flat Plate with an Imposed Temperature Distribution Abstract: A numerical algorithm is presented for studying Marangoni convection flow over a flat plate with an imposed temperature distribution. Plate temperature varies with x in the following prescribed manner: where A and k are constants. By means of similarity transformation‚ the original nonlinear partial differential equations of flow are transformed to a pair of nonlinear

Floating Balloon Purpose : To demonstrate the principle of buoyancy of warm air. Additional information : The density variation between warm and cool air can be used to explain why warm air possesses higher buoyancy. As hot air contain atoms and molecules with higher kinetic energy than cold air‚ it has a lower density and rises up while the colder air goes downwards
