    Flow chart is as shown in the figure. Reaction: C2H5OH Catalyst: Æ CH3CHO + H2 Cu -Co-Cr2o3 Temperature: 280 – 3500 C. Process description: The raw material i.e.‚ ethanol is vaporized and the vapors‚ so generated‚ are heated in a heat exchanger to the reaction temperature by hot product stream. The product stream is cooled to –100 C and in doing it‚ all unreacted ethanol and acetaldehyde are condensed. The out going gaseous stream‚ containing hydrogen mainly‚ is scrubbed with dilute

    Glow Stick Lab – Informal Hypothesis: I believe the glow sticks will become ultimately brighter in the warmer temperature beaker as heat cause molecules and particles to move faster and rapidly thus producing energy where as when the glow stick is the cold temperature beaker I believe it will dim in light as energy id being taken away as particles are moving much slower and are closer to each other. Materials: * Hot plate * Two beakers (200mL) * Two glow sticks * Water * Thermometer

    Theory: To most people heat and temperature are generally the same thing. But really in a scientific sense there is still a similarity between them but they are different concepts. Temperature is the measure of the average energy of molecular motion in a substance. Heat is the total energy of molecular motion in a substance. Temperature is not energy like heat is‚ it is just measure of it. Now there is also a difference between heat and thermal energy. Heat is an energy that is transferred

    or not. It is the second law of thermodynamics which provides the criterion as to the probability of various processes through the statements of Clausius that ‘’Heat does not pass from a body at low temperature to one at high temperature without an accompanying change elsewhere’’ and Kelvin that ‘’No cyclic process is possible in which heat is taken from a hot source and converted completely into work’’. The aim of this essay is to prove if there equivalence between these two statements and it will

    Thermodynamics: Entropy

    • 953 Words
    • 4 Pages

    Thermodynamics is the branch of science concerned with the nature of heat and its conversion to any form of energy. In thermodynamics‚ both the thermodynamic system and its environment are considered. A thermodynamic system‚ in general‚ is defined by its volume‚ pressure‚ temperature‚ and chemical make-up. In general‚ the environment will contain heat sources with unlimited heat capacity allowing it to give and receive heat without changing its temperature. Whenever the conditions change‚ the thermodynamic

    without glass plate‚ cold jet of air impinges INTRODUCTION: Solar ray collectors transform solar radiation into heat and transfer that heat to water. Then solar heat can be used for heating water‚ to back up heating systems. The heart of a solar collector is the absorber‚ which is usually composed of several narrow metal strips. The carrier fluid for heat transfer flows through a heat-carrying pipe‚ which is connected to the absorber strip. In plate-type absorbers‚ two sheets are sandwiched together

    work. I predict that for temperature‚ it will not be a case of an increase in x = an increase in y. I predict that there will be a peak where photosynthesis happens the quickest at around 40-50°C. Chlorophyll is an enzyme‚ therefore it requires some heat to work‚ but if it is overheated it stops working. Enzymes work rather like a lock and key. It is important that they are a very specific shape for their purpose (in this case chlorophyll joins
