Activation energy

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…

In his podcast, “Hallelujah,” Malcolm Gladwell explains that the difference between being a conceptual innovator and an experimental innovator is essentially time and experience. Experimental innovators, Gladwell explains, are like marathoners. They take their time and work slowly towards their goals; no matter how long it takes them, they know at some point that there will be an end, they just don’t know when their work will end and stop changing. Conceptual innovators on the other hand, are…

the Tesla Model S will be used. It will not be completely accurate because many modifications to the car will be made, but it will serve as a decent sample. The car itself will depend on three main power sources: solar power, wind power, and kinetic energy recovery, or more commonly known as regenerative braking. The solar panels will cover the top of the car, which is about 105.214 feet squared, or about 9.775 meters squared (Model S). However, the windows cannot have solar panels on them as…

In addition, higher SGR of V. parahaemolyticus was observed as the temperature increases. The MPD values of V. parahaemolyticus varies from the lowest 7.00 to the highest 8.91, regardless of the type of V. parahaemolyticus strain at the 3 different temperatures. The differences in LT values were increased as the temperature was increased. At 20 °C, the shortest LT was observed with the (tlh+) strain, followed by (tdh+/trh+), the mixture, the (tdh+) and the (trh+). At 25°C the strains likely kept…
