href="/wiki/Fasediagram" title="Fasediagram">fasediagram</a>. De gestippelde groene lijn geeft het bijzondere gedrag van <a href="/wiki/Water" title="Water">water</a> weer.</figcaption></figure> <p>Een <b>tripelpunt</b> is een toestand waarbij een stof tegelijkertijd voorkomt in de drie <a href="/wiki/Fase_(stof)" title="Fase (stof)">"hoofdfasen"</a> (<a href="/wiki/Vaste_stof" title="Vaste stof">vast</a>, <a href="/wiki/Vloeibaar" class="mw-redirect" title="Vloeibaar">vloeistof</a> en <a href="/wiki/Gas_(aggregatietoestand)" title="Gas (aggregatietoestand)">gas</a>) die onderling in <a href="/wiki/Evenwicht" title="Evenwicht">evenwicht</a> zijn. Het tripelpunt kan omschreven worden als het <a href="/wiki/Smeltpunt" title="Smeltpunt">smeltpunt</a> van de stof onder haar eigen <a href="/wiki/Dampdruk" title="Dampdruk">dampdruk</a>. </p><p>Het bekendste is het tripelpunt van <a href="/wiki/Water" title="Water">water</a>: als vloeibaar water naast <a href="/wiki/Ijs_(water)" class="mw-redirect" title="Ijs (water)">ijs</a> en <a href="/wiki/Waterdamp" title="Waterdamp">waterdamp</a> voorkomt, is de temperatuur <i>T</i> per definitie 0,01 graden <a href="/wiki/Celsius" title="Celsius">Celsius</a> of 273,16 <a href="/wiki/Kelvin_(eenheid)" title="Kelvin (eenheid)">kelvin</a> (de tripelpunttemperatuur) bij een druk <i>P</i> van 611,73 <a href="/wiki/Pascal_(eenheid)" title="Pascal (eenheid)">pascal</a> (ongeveer 0,006 <a href="/wiki/Atmosfeer_(eenheid)" title="Atmosfeer (eenheid)">atmosfeer</a>, de tripelpuntdruk). </p><p>Het bijzondere van het tripelpunt is, dat voor <a href="/wiki/Zuivere_stof" title="Zuivere stof">zuivere stoffen</a> daar de temperatuur en de druk vastliggen. Volgens de <a href="/wiki/Fasenregel" title="Fasenregel">fasenregel</a> is het systeem dan invariant: noch <i>P</i>, noch <i>T</i> kan gekozen worden. Alleen de verhoudingen van de verschillende fasen, dat wil zeggen de verhouding aan vaste stof, vloeistof en gas, kan variëren. Bijvoorbeeld, veronderstel een afgesloten vat met ijs, water en waterdamp. Bij toevoer van warmte aan dit vat zal een deel van het ijs smelten, en omdat het waterniveau hetzelfde blijft, zal het water niet verdampen. De druk en de temperatuur blijven dan gelijk. Pas als al het ijs is gesmolten, zal de toevoer van warmte het water in temperatuur doen toenemen, en daarmee de druk langs de kooklijn. </p><p>Wanneer ijs bij een druk boven de tripelpuntdruk wordt bewaard, en er dus geen waterdamp is, dan zal het bij verwarmen alleen <a href="/wiki/Smelten_(faseovergang)" title="Smelten (faseovergang)">overgaan</a> in vloeibaar water. Wanneer ijs bij een temperatuur beneden de tripelpunttemperatuur wordt bewaard, dan zal het bij de sublimatiedruk (rode lijn in figuur hiernaast) in evenwicht zijn met de gasfase. Wanneer de druk verlaagd wordt komt de vloeibare fase niet meer voor, het water zal dan direct vanuit de vaste fase <a href="/wiki/Sublimatie" title="Sublimatie">sublimeren</a> naar de gasfase, totdat al het ijs verdwenen is. </p> <div class="mw-heading mw-heading2"><h2 id="Tripelpunt_van_verschillende_stoffen">Tripelpunt van verschillende stoffen</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Tripelpunt_(natuurkunde)&veaction=edit&section=1" title="Bewerk dit kopje: Tripelpunt van verschillende stoffen" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Tripelpunt_(natuurkunde)&action=edit&section=1" title="De broncode bewerken van de sectie: Tripelpunt van verschillende stoffen"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Van enkele eenvoudige stoffen staan hieronder de temperatuur en druk van het tripelpunt, gesorteerd op temperatuur. </p> <table class="wikitable"> <tbody><tr> <th>Stof </th> <th>Temperatuur<br />(K) </th> <th>Druk<br />(kPa) </th></tr> <tr> <td><a href="/wiki/Waterstof_(element)" title="Waterstof (element)">waterstof</a> </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">0</span>13,8033 </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">00</span>7,04 </td></tr> <tr> <td><a href="/wiki/Neon_(element)" title="Neon (element)">neon</a> </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">0</span>24,5561 </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">0</span>43,2 </td></tr> <tr> <td><a href="/wiki/Dizuurstof" title="Dizuurstof">zuurstof</a> </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">0</span>54,3584 </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">00</span>0,152 </td></tr> <tr> <td><a href="/wiki/Argon" title="Argon">argon</a> </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">0</span>83,8058 </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">0</span>68,8 </td></tr> <tr> <td><a href="/wiki/Koolstofdioxide" title="Koolstofdioxide">kooldioxide</a> </td> <td>216,5<span style="visibility:hidden;color:transparent;" aria-hidden="true">000</span> </td> <td>518,5 </td></tr> <tr> <td><a href="/wiki/Water" title="Water">water</a> </td> <td>273,1598 </td> <td><span style="visibility:hidden;color:transparent;" aria-hidden="true">00</span>0,61173 </td></tr></tbody></table> <div class="mw-heading mw-heading2"><h2 id="Toekomst">Toekomst</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Tripelpunt_(natuurkunde)&veaction=edit&section=2" title="Bewerk dit kopje: Toekomst" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Tripelpunt_(natuurkunde)&action=edit&section=2" title="De broncode bewerken van de sectie: Toekomst"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Volgens de <a href="/wiki/Herdefinitie_van_de_basiseenheden" class="mw-redirect" title="Herdefinitie van de basiseenheden">herdefinitie van de basiseenheden</a> krijgt de <a href="/wiki/Kelvin_(eenheid)" title="Kelvin (eenheid)">kelvin</a> een nieuwe definitie, gebaseerd op een bepaalde exacte waarde van de <a href="/wiki/Boltzmannconstante" title="Boltzmannconstante">Boltzmannconstante</a>.
