I am trying to achieve an understanding of this occurances to be able to recognize them myself. Thanks. <br> Terry Holbrook </b> <p><b></b></p> </dt> <dd> When trying to classify a process as exothermic or endothermic, watch how the temperature of the surroundings changes. An exothermic process releases heat, and causes the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings. Can you think of a way to test the classification of each of these processes? <p></p> <table cellpadding="10" border="1" cellspacing="0"> <tbody> <tr bgcolor="GAINSBORO" align="CENTER"> <td><b>Exothermic processes</b></td> <td><b>Endothermic processes</b></td> </tr> <tr valign="TOP"> <td>making ice cubes</td> <td>melting ice cubes</td> </tr> <tr valign="TOP"> <td>formation of snow in clouds</td> <td>conversion of frost to water vapor</td> </tr> <tr valign="TOP"> <td>condensation of rain from water vapor</td> <td>evaporation of water</td> </tr> <tr valign="TOP"> <td>a candle flame</td> <td>forming a cation from an atom in the gas phase</td> </tr> <tr valign="TOP"> <td>mixing sodium sulfite and bleach</td> <td>baking bread</td> </tr> <tr valign="TOP"> <td>rusting iron</td> <td>cooking an egg</td> </tr> <tr valign="TOP"> <td>burning sugar</td> <td>producing sugar by photosynthesis</td> </tr> <tr valign="TOP"> <td>forming ion pairs</td> <td>separating ion pairs</td> </tr> <tr valign="TOP"> <td>Combining atoms to make a molecule in the gas phase</td> <td>splitting a gas molecule apart</td> </tr> <tr valign="TOP"> <td>mixing water and strong acids</td> <td>mixing water and ammonium nitrate</td> </tr> <tr valign="TOP"> <td>mixing water with an anhydrous salt</td> <td>making an anhydrous salt from a hydrate</td> </tr> <tr valign="TOP"> <td>crystallizing liquid salts (as in sodium acetate in chemical handwarmers)</td> <td>melting solid salts</td> </tr> <tr valign="TOP"> <td>nuclear fission</td> <td>reaction of barium hydroxide octahydrate crystals with dry ammonium chloride</td> </tr> <tr valign="TOP"> <td>mixing water with calcium chloride</td> <td>reaction of thionyl chloride (SOCl<sub>2</sub>) with cobalt(II) sulfate heptahydrate</td> </tr> </tbody> </table> <p><font size="-1"> Author: <a href="https://web-archive-org.translate.goog/web/20161119015855/http://antoine.frostburg.edu/chem/senese/index.shtml?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB">Fred Senese</a><a href="https://web-archive-org.translate.goog/web/20161119015855/mailto: senese@antoine.frostburg.edu?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB"> senese@antoine.frostburg.edu</a></font></p> </dd> </dl><p></p></font></td> </tr> <tr valign="TOP"> <td><font face="geneva,Helvetica,Arial,sans-serif" size="-2"></font></td> <td></td> <td><br clear="all"><p><a name="bottom"></a></p> <hr noshade><font size="-2" face="geneva,Helvetica,Arial,sans-serif"><a href="https://web-archive-org.translate.goog/web/20161119015855/http://antoine.frostburg.edu/chem/senese/101/index.shtml?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB">General Chemistry Online!</a> What are some examples of exothermic and endothermic processes? <p>Copyright 漏 1997-2010 by <a href="https://web-archive-org.translate.goog/web/20161119015855/http://antoine.frostburg.edu/chem/senese/index.shtml?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB">Fred Senese</a><br> Comments & questions to <a href="https://web-archive-org.translate.goog/web/20161119015855/mailto:fsenese@frostburg.edu?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB">fsenese@frostburg.edu</a><br> Last Revised 08/17/15.URL: <a href="https://web-archive-org.translate.goog/web/20161119015855/http://antoine.frostburg.edu/chem/senese/101/thermo/faq/exothermic-endothermic-examples.shtml?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" target="_TOP">http://antoine.frostburg.edu/chem/senese/101/thermo/faq/exothermic-endothermic-examples.shtml</a><br></p></font></td> </tr> </tbody> </table></font> <script>function gtElInit() {var lib = new google.translate.TranslateService();lib.translatePage('en', 'en', function () {});}</script> <script src="https://translate.google.com/translate_a/element.js?cb=gtElInit&hl=en-GB&client=wt" type="text/javascript"></script> </body> </html>
