transferred by warm liquids or gases. Warm air is less dense than cold air because particles have more energy so they spread further. So the hot air rises and transfers heat and the cold air replaces it Radiation: all objects give out and take in thermal radiation which is also called infrared radiation. The hotter an object is the more infrared radiation it emits. It travels in waves not involving any particles‚ which is why the heat from the sun can travel through space. If the body gets to hot

of Part A in this experiment‚ it can be determined that Sodium Chloride had the highest amount of conductivity tested by all groups. On the graph above‚ the data shows that NaCl (sodium chloride) held the highest amount of electrical conductivity for all groups and on the table it reads the highest numbers across its row. Also as seen in the data above‚ ethanol had the lowest amount of conductivity with sucrose‚ acetic acid‚ ammonia‚ and MgCl2 following in ascending order. It can also be determined

of the wire increases every 10°C until the highest temperature is reached and the measurements are recorded. Conclusion The hypothesis that when the temperature of a wire increases‚ the resistance value of the wire will also increase and the conductivity of the wire will reduce is proven to be true. The temperature of the wire increases due to its power loss‚ which is calculated as I2x R.‚ where “I” is the current in the wire and R is the resistance. The higher the current in the wire or the higher

Latent Heat Thermal Storage Using Phase Change Materials (PCM) Aniruthan .M.E ABSTRACT Department of Mechanical Engineering‚ Anand Institute of Higher Technology‚ Chennai. Various methods are employed in production of energy throughout the globe. Some prove as perennial resource‚ however many of them undergoes many loses in the intermediate conversion process from initial stage to the final stage of power production. Also supply and demand don’t quite meet their ends often. To reduce this mismatch

How H-P Used Tactics of the Japanese to Beat Them at Their Game 1) Before introducing its inkjet printers‚ did H-P have to estimate the demand curve for them? Why or why not? Answer: In 1984 HP came up with first Inkjet Printer‚ which was quite far from the perfect to be a complete knock-out. HP was not only the inventor of the Inkjet printer it was as well the manufacturer of the low cost inkjet printers. Before HP has launched its Inkjet printers there were no market existed for it

Thermal Imaging This article is about the infrared imaging technique. For the printing technique called thermography. Thermogram of a traditional building in the background and a "passive house" in the foreground Infrared thermography (IRT)‚ thermal imaging‚ and thermal video are examples of infrared imaging science. Thermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9‚000–14‚000 nanometers or 9–14 µm) and produce images of that radiation

Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3 Na2CO3 + CO2 + H2O 2NaHCO3 Na2O + 2CO2 + H2O Variables: Independent: Original
