P LANNING Aim: Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance‚ which alters the speed‚ or rate of a chemical reaction but is chemically unchanged at the end of the reaction. The two factors that we can change are the temperature and the concentration. We chose to vary the concentration of hydrogen peroxide. The catalyst to speed up the reaction without affecting the result will be manganese

The Chemistry of Decomposition Decomposition is defined as the biological and chemical changes a body undergoes after death. It is the decay of tissues and structures. There are two types of decomposition: abiotic and biotic. Abiotic decomposition is defined as the degradation of a substance by chemical or physical processes; such as hydrolysis‚ reduction‚ or oxidation. Biotic decomposition is the metabolic breakdown of materials into simpler components by living organisms. This is typically

Hydrogen has a high specific energy‚ high flame speed‚ wide range of flammability‚ and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development. In the early 1990s‚ FSEC conducted research on using hydrogen in an ICE. This work resulted in the development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue

of how good a material is at conducting heat is known as its thermal conductivity. Thermal conductivity is defined as the rate at which heat flows through a certain area of a Object of the experiment is to determine the thermal conductivity of metals and insulation body.materials and also to demonstrate that heat flow is directly proportional to temperature differences between faces and to cross sectional area. Thermal conductivity is defined as:

PHYSICS FORM: 4D & 4E TOPIC: THERMAL PHYSICS Temperature determines the direction of net heat flow. It is the property o f an object. It’s the amount of kinetic energy a body possesses. Example Brass rod made hot at one end by placing it in a Bunsen flame‚ while other end is kept away at room temperature‚ there is a net transfer of energy from the high temperature region to the low temperature end.

Experiment 1: Thermal Linear Expansion Abstract: The thermal linear expansion of copper and aluminum is the focus of this experiment where the two metals have a tendency to expand their length in response to the change of temperature. Each metals have their own coefficient of linear expansion which describes how the size of an object changes with a change in temperature while the pressure is held constant. We ’re able to determine the theoretical coefficient of linear expansion of the two metals
