Basic cooking principle CONDUCTION Conduction occurs in two ways: 1. When heat moves directly from one item to another part of item example‚ from the top of the range to a soup pot placed on it‚ from the pot to the broth inside‚ and from the broth to the solid food items in it. 2. When heat moves from one part of something to an adjacent part of the same item for example‚ from the exterior of a roast to the interior‚ or from a sauté pan to its handle. Different materials conduct heat at different

Given the unknown colourless liquid it is essential that the structure is derived. Firstly it is important to determine the percentage composition of elements to work out the empirical formula. The empirical formula was found to be C10H12O and the mass of the unknown was 148.09 m/z which when calculating the molecular weight of the empirical formula it did equal 148.09 g mol -1. This means that the empirical formula is also the molecular formula. As 12.01x10 carbons +1.008x12 hydrogens + 16= 148

indicator lamps in many devices and are increasingly used for other lighting. Appearing as practical electronic components in 1962‚[7] early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness. When a light-emitting diode is switched on‚ electrons are able to recombine with holes within the device‚ releasing energy in the form of photons. This effect is called electroluminescence and the color of

Astronomy: Discovery of Uranus by William Herschel in 1781 William Hershal was a telescope maker and with the invention of the telescope was the motivation that led to the discovery. Because the calculated orbit of Uranus did not compare accurately with the observed orbit‚ astronomers concluded that a disturbing influence was present. A study of this irregularity led to the discovery of Neptune in 1846. (Columbia Electronic Encyclopedia‚ 6th Edition. Q2 2016‚ p1-1. 1p.) At first it was thought

Tomas BSIT-4B TRANSMISSION MEDIA The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications. Infrared Infrared transmission is usually limited to a small area‚ e.g. one room‚ with the transmitter pointed towards the receiver. The hardware is inexpensive and does not require an antenna.

The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the

Finally this catalyst is being characterized using three methods which are the infrared spectra‚ X-ray diffraction as well as the TGA and DTA methods. 2.0 Introduction Catalyst is a substance that causes the change in rate of a chemical reaction. This reaction is known as catalysis and unlike other reagents that take
