rate of amylase reaction. Research title The effect of temperature on amylase activity. Word count-1025 Background research Enzymes are catalysts which speed up reactions in living organisms. Enzymes function by decreasing the activation energy for a reaction. Amylase is an enzyme found in human saliva and catalyses the hydrolysis of starch .Amylase like all other proteins have secondary and tertiary structures which are affected by temperature, pH and other factors. Due to the fact…

Material selection The main purpose of outer material is to provide enough insulation. So minimum heat transfer coefficient is required for the outer material. Other selection criteria are: 1. Cost 2. Environment friendly 3. Availability Alternatives along with heat transfer coefficient are: • Wood : 0.19 w/m/k • Plastics: 0.29 w/m/k • Polystyrene foam: 0.04 w/m/k • Polyurethane foam: 0.03 w/m/k From the above alternative more suitable outer materials are Polystyrene foam and Polyurethane…

GEOTHERMAL ENERGY 1.1 INTRODUCTION AND DEFINITION Geothermal energy is the utilization of heat present in the deep earth for the purpose of power generation or other direct use application. In general terms, geothermal energy consists of the thermal energy present in the Earth’s crust. Thermal energy in the earth is distributed between the constituent host rock and the natural fluid that is contained in its fractures and pores at temperatures above ambient levels. Globally, the most commonly…

Heat conduction mechanism represents the energy loss at the particle surface due to the collisions with the surrounding gas molecules. There is no simple theory to explain the cooling mechanism of the particles. During the laser pulse, the particle achieves the peak temperature and emit thermal signal. After the laser pulse duration, the particle starts to cool down. The cooling of the particles is characterized by a decay function. The decay of LII signal provides information about the primary…

The storage modulus, (E՛) is proportional to the energy stored per cycle, the loss modulus; (E″) is proportional to the lost or dissipated energy per cycle. The storage modulus characterizes the elastic behavior of the material, and the loss modulus characterizes the viscous behavior of the material. The ratio of energy dissipated to energy stored is the tangent of the phase angle, δ, called tanδ, which is given by tan⁡δ=(E^" (ω))/(E^' (ω)) In…

calorimeter heat energy was pushed out. Then we took it another step further by modifying our calorimeter to capture even more energy. The overall purpose was to capture as much energy as possible. “Energy is the ability to do work, or the ability to elicit change in matter.” (Castro) Energy can be defined in different ways as well. Kinetic energy is energy that results from movement. (Castro) An example would be water flowing through a hydro dam. (What is…) Potential energy is energy that is…

The procedure of the experiment includes two parts: 1. Determination of the Freezing Point of Glacial Acetic Acid: to record the temperature of acetic acid every 30 seconds until it reach 300 seconds (5 minutes). 2. Determination of the Molar Mass of an Unknown Compound: to record the temperature of the mixture between unknown solid and glacial acetic acid. After that, put the ice-water mixture into the tube and record the temperature every 30 seconds. Pre lab questions: 1. Solute: dissolved…

Power Plant. His job place always dealing with radiation around him and his co-workers. But we don’t know deep details about radiation. Let’s start by talking about the thermal radiation. Thermal radiation is energy where it transfers by the emission of electromagnetic waves. The waves hold energy away from releasing object. For a normal temperature, the radiation is in the infrared region of the electromagnetic spectrum. The relationship ,conducting the net radiation from a hot object is…

There are two main reasons people buy a hot tub: for relaxation and health. Moreover, if you choose to install an outdoor hot tub, you can already consider it the centerpiece of a get-together with family and friends. Actually, it's all about relaxation. On the other hand, when it comes to health, the hot tubs have the ability to relieve pain and tension in your body. However, in order to help you, we have gathered some of the finest hot tubs for your outdoor relaxation. Softub T220 Have you…

Winterize Your Home’s Plumbing Before It’s Too Late Winter can be a problematic time for homeowners. You run the risk of having pipes in your home that freeze, causing the water inside to expand and the pipe to burst. Not only do you have a plumbing repair that needs to be done as a result, but you will have water damage in your home. The same thing can happen outside of your home as well when you don’t take preventative steps before winter comes. Thankfully, winterizing your home’s plumbing is…
