Investigation into transition metals as catalysts

Hydrogen peroxide decomposes slowly to form water and oxygen gas. Transition metal oxides will catalyse this reaction. A catalyst speeds up a reaction without being used up. The best catalyst for a reaction increases the rate of reaction the most. The rate of reaction can be measured by the amount of product formed divided by… View Article

Estimated Heat Distribution by Convection in Water

Introduction This report assesses the distribution of heat by convection in water to estimate the heat conductivity of water. The transfer of heat from a heating coil to a fluid is conduction but the heat transfer within the fluid is convection. This is basically fluid flow of particles arising from nature, heat, chemical or kinetics…. View Article

Determination of Density

Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size, the denser one may feel heavier. If their densities are close together, it can be… View Article

Investigatory Project “ Kaymito Leaves Decoction as Antiseptic Mouthwash ”

Introduction 1.1 Problem Statement Fractures are prevalent in natural and synthetic structural media, even in the best engineered materials. We find fractures in bedrock, in sandstone aquifers and oil reservoirs, in clay layers and even in unconsolidated materials (Figures 1.1 to 1.4). Fractures are also common in concrete, used either as a structural material or… View Article
