Heat transferred - Study guides, Class notes & Summaries

Conduction - Answer-direct transfer of energy from molecule to molecule via direct molecular collsions What are the best and worst conductors? - Answer-Worst= gases Best= metals Convection - Answer-heat transfer by physical motion; only takes place in fluids and gases. Heat energy is transferred AWAY from the source. Radiation - Answer-transfer of energy by electromagnetic waves. Radiation can travel through a hard vacuum. Ex: energy from sun specific heat - Answer-c, amount of he...

4 basic laws of thermodynamics - ANSWER zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp system one unless additional work is done 3rd law: states that as a t...

how is heat transferred from place to place? - Answer conduction, convection, radiation What surface is better at absorbing heat? - Answer dark matt surfaces what surface is better at reflecting heat? - Answer light shiny surfaces what objects emit infared radiation? - Answer all objects. the hotter it is, the more it emits. what does infared radiation involve? - Answer waves! not particles what can radition pass through? - Answer vaccum particles in solids, l...

what is the purpose of the CPU? to process data by following the fetch-decode-execute cycle, it's incharge of searching, sorting, calculating and decision making what happens at the fetch stage? the CPU fetches data and instructions from RAM and then stores them in it's own temporary memory called registers Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:00 Full screen what happens at the decode stage? the CPU und...

Praxis 5442 - Physical Science Latest Update Graded A+ [Ca(NO3)2] calcium nitrate 1st law of thermodynamics The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed. 2nd law of thermodynamics The principle whereby every energy transfer or transformation increases the entropy of the universe. Ordered forms of energy are at least partly converted to heat, and in spontaneous reactions, the free energy of the system also...

How Can you lose your license? - Answer Drinking on the job, sleeping, negligence, unsafe work, failing to renew license, signing a falsified licensing application. What must you do if you change jobs? - Answer You must notify City Hall if you change jobs, change address or retire Why should you do rounds? - Answer To find and correct problems, prevent breakdowns, keeping permanent records will make it easier to forecast most breakdowns because you will get to know your equipment. ...
