Heat‚ Kinetic Energy and Temperature SCI 110 02/01/2013 The study of heat relate to Kinetic theory of matter is that universe is made up of matter and energy. Matter is made up of atoms and molecules. Atoms and molecules are always in motion because energy. Energy forces them to contact into each other or vibrate back and forth. When this happens molecules and atoms

Determining the Specific Heat of an Unknown Metal Objective: To determine the specific heat of an unknown metal through the use of a calorimeter. Background: The specific heat of any substance represents the quantity of heat energy in joules required to heat one gram of the substances by one °C. The specific heat of a substance is dependent upon the temperature; this means that there is a temperature range for which the specific heat of a substance applies. For metals and metallic substances

surface that absorbs less heat‚ and remains cooler. There are several factors that cause higher temperatures in urban area like dark rooftops‚ dark asphalt surfaces‚ and more buildings with more emitted heat from air conditioners and furnaces and denser traffic which cause elevated emissions of air pollutants. Dark roofs and dark asphalt surfaces have much lower albedos than rural areas‚ and this causes a buildup of heat in cities during the summer months and because the heat absorbed by the paved

sunlight to heat energy and retaining the heat for cooking. To make the process work‚ you cover as much of the box as possible with reflective material in order to catch as much sunlight as possible. In this case‚ you are using tin foil. The cooking surface is black construction paper because it retains heat very well. If you’ve ever worn a black shirt on a sunny day‚ or sat down on the black seat of a car in the summer‚ you know that black surfaces absorb and retain a lot of heat. Ouch! As heat is retained

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
