He was totally drunk, and began yelling and swearing at people for no reason. Liquid metal coming in contact with such a surface forms a crust of solidified metal over it, and this crust thickens up to a certain point, namely, until the heat from within the furnace just overbalances that lost by conduction through the solidified crust and the cathode material to the flowing water. Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Given a certain allowable heat transmission, the principal points to be considered in connexion with insulation are, first cost, durability, weight and space occupied, the two last named being specially important factors on board ship. The conduction through the amputated cell branches continues unimpaired for many hours. - The theory of conduction of heat by diffusion in gases has a particular interest, since it is possible to predict the value on certain assumptions, if the viscosity is known.

He also determined the effect of change of temperature distribution on the rate of generation of heat by the current; and on the external loss of heat by radiation, convection and conduction. Conduction, often called thermal conduction or heat conduction, is the transfer of heat through a temperature gradient. Heat conduction: Students can gather different types of coins, pieces of fabric and other materials to see which can hold heat best by recording the temperature of each after a set amount of time. Conduction is the transfer of energy through matter from particle to particle --- or from atom to atom within a substance. conduction of experiments. Wilson considers that convection currents in the upper atmosphere would be quite inadequate, but conduction may, he thinks, be sufficient alone. Conduction aphasia, also called associative aphasia, is an uncommon form of difficulty in speaking ().It is caused by damage to the parietal lobe of the brain. Though sound traveling through the air is the most common example of conduction, it happens when sound travels through a solid surface like the wall of a room as well. Heartbeat abnormalities such as tachycardia (rapid heart rate) and heart block (impaired conduction of the heart's cardiac impulses) are common occurrences. It simplifies the theory, and gives a possible relation between the constants, but it does not appear to remove the complication above referred to, which seems to be inseparable from any conduction theory.

While it seems clear that the conduction in this case is carried on by ions similar to those of solutions, since Faraday's laws apply equally to both, it does not follow necessarily that semi-permanent dissociation is the only way to explain the phenomena. Frequent Predecessors. An example of a sentence with the word would be: "The metal material was a great choice for a conduction … The fact that conduction occurred preponderantly in certain directions was explained by appeal to a hypothetical resistance to conduction which, for reasons unascertained, lay less in some directions than in others. ABSTRACT Repetition is viewed typically as a primary deficit in conduction aphasia. Conduction definition is - the act of conducting or conveying. In ordinary cases conduction and convection suffice to dissipate the heat generated by the brake, but when a great deal of lowering has to be rapidly performed, or heavy loads have to be lowered to a great depth, special arrangements have to be provided. The patient wears headphones when air conduction is tested and a vibrating earpiece behind the ear next to the mastoid bone or along the forehead when bone conduction is tested. 3. The presence of these threads between all the cells of tfie plant shows that the plant body must be regarded as a connected whole; the threads themselves probably play an important part in the growth of the cell-wall, the conduction of food and water, the process of secretion and the transmission of impulses. the process by which sound waves travel through another material, The conduction of sound through the air is what allows us to hear all of the noise around us, since we wouldn’t hear anything if the sound didn’t travel to our ears from its source. Conduction, however, is generally understood to include diffusion of heat in fluids due to the agitation of the ultimate molecules, which is really molecular convection. Relevance. Graham showed that the diffusion was approximately proportional to the difference in concentration, and on these lines a theory of diffusion was founded on the lines of Fourier's treatment of the conduction of heat. In addition to the systems of wireless or space telegraphy depending upon conduction through earth or water, and the in ductive system based upon the power of a magnetic Eelson. Conduction can occur in liquid, gaseous or solid objects. The charges moving in a conductor constitute a conduction current, while those moving in a vacuum constitute a convection current.

Thomson's calculations on the conduction of heat showed that at some time between twenty millions and four hundred millions, probably about one hundred millions, of years ago, the physical conditions of the earth must have been entirely different from those which now obtain. Similarly, from a hydrogeological point of view, rapid convection of meteoric waters is known from intermontane rift basins. Favorite Answer. •When you touch one hot surface to another, the hot molecules bump into the other molecules which makes them start to move faster. Thomson has shown (see CONDUCTION, ELECTRIC, § III.) See more. For conduction to occur between atoms within the same object, they must also be touching (or nearly touching). The subject is dealt with in Electrolysis and Electric conduction: § dealt with the relations between the properties of an ideally dilute solution, we now turn to the consideration of the general case where the simplifying assumption of great dilution is not made. Wilson supposes that by the fall to the ground of a preponderance of negatively charged rain the air above the shower has a higher positive potential than elsewhere at the same level, thus leading to large conduction currents laterally in the highly conducting upper layers.
