Internal energy

important to give a brief introduction of the concept of energy to then fathom the topics of thermodynamics, entropy, and enthalpy, and their relation to biology. Energy is a seemingly intuitive…

Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a rigid body Similarities - Conservation of energy -…

Graph 3.1 shows the rate of heat transfer due to ventilation, through the window, door and wall over a period of 7 days. The total rate of heat transfer for all components are also plotted in the graph. The rate of heat loss fluctuated with respect to time for all components and recorded maximum and minimum rates at similar times. The rate of heat transfer through the door is not only the highest in values but also in variation in temperatures. A more detailed representation of the data…

maintain the generated heat within their systems to maintain their bodies at a constant temperature. If temperatures increase or decrease above or below the desired constant temperature or thermo neutral zone, these organisms have to do work and spend energy in order to reach a constant metabolic rate. The metabolic activity seen among both endothermic and ectothermic organisms varied in the different environmental…

Nuclear Fusion Ten million years after the shock wave, the star is officially born when it reaches an internal temperature of 10 million degrees Kelvin. At this pivotal temperature, the individual hydrogen protons are unable to repel each other any longer, and collide into each other forming a helium atom. This process not only forms a higher element, but also releases energy. It is this energy that we see as sunshine or light, and can feel as heat. By the time it has reached this…

Energy production Jigsaw Project individual Selena Xu 1. Second law of thermodynamics: ❖ What is the second law of thermodynamics? Well, this law talks about the quality of energy, while the quantity of energy and matter stays constant. This law tells us that heat will flow from a hotter object to a colder object, due to Newton’s second law and that when energy is transferring and transforming, some of the useful energy might be lost . ❖ Cyclic process of energy transfer is a when a series…

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…

flow. In other words, it is the “thickness” or “thinness” of a fluid. The internal friction or resistance it has as well as the temperature in which the fluid is at determines the viscosity of the substance as well. If there is more internal resistance or friction, then the particles of the substance won’t slid past each other as easily and therefore make the substance more viscous. On the other ha2145nd, if there is less internal resistance or friction, then the particles of the substance will…

with the environment (Akin, 2011; Kemp & Krockenberger, 2002;). In Biomimicry, through studying thermoregulation, human beings can apply nature’s techniques to architecture when designing buildings. Present temperature systems are using a lot of energy, especially to control heat and cooling loads. (Carpi 2010). Thermoregulatory mechanisms include passive thermoregulation and active thermoregulation; by studying butterflies and birds more effective climate systems can be developed, leaving a…

The Effect Of Temperature On The Rate Of Maggot Movement. Environmental Systems and Societies ---Planning Lab--- Gaurav Iyer Research Question To what extent does the temperature affect the movement of Maggots? Introduction The Experiment aims to analyze the behaviour of the maggots. In this case, behaviour is defined as the way organisms respond to their environment. In the experiment, the orientation of the movement of organisms and gametes in response…
