<p><b>Neue Seite</b></p><div>{{navi|Wärmemenge|spezifische Wärmekapazität}}<br />
Beim Temperaturausgleich zwischen zwei Körpern stellt sich eine Mischungstemperatur ''T''<sub>m</sub> ein, es gilt:<br />
<br />
<br />
<br />
Die Wärmemenge ''Q'' ist die '''Wärmeenergie''' in [[Joule]], die vom wärmeren auf den kälteren Körper übertragen wird.<br />
<br />
Die Wärmemenge ist umso größer, je ...<br />
* schwerer der Körper ist ([[Masse]])<br />
* höher die Temperaturdifferenz Δ''T''<br />
* größer seine [[spezifische Wärmekapazität]] ''c'' ist, zusammengefasst:<br />
<br />
<br />
{{Formel|1=''Q'' = ''c''{{*}}''m''{{*}}Δ''T''}}<br />
<br />
<br />
== Beispiel ==<br />
<br />
In eine Tasse aus Porzellan (21 °C, 300 g) wird 0,3 L 95°C-heißes Teewasser eingeschenkt. Welche Mischungstemperatur stellt sich ein?<br />
* Gegeben: ''m'' = 200 g; Δ''T'' = 70 [[Kelvin|K]]; ''c''(Wasser) = 4,18 J{{*}}g<sup>-1</sup>{{*}}K<sup>-1</sup> (s. Tabelle der [[spezifische Wärmekapazität|spezifischen Wärmekapazität]]en)<br />
* Gesucht: Wärmemenge ''Q'' in [[Joule|J]]<br />
* Lösungsformel: ''Q'' = ''c''{{*}}''m''{{*}}Δ''T''<br />
* Einsetzen: ''Q'' = 4,18 J{{*}}g<sup>-1</sup>{{*}}K<sup>-1</sup>{{*}}200 g{{*}}70 [[Kelvin|K]]<br />
* Ausrechnen: ''Q'' = 58.520 [[Joule|J]]<br />
* Antwort: Für die Zubereitung einer Tasse Kaffee ist unter den gegebenen Umständen eine Wärmemenge von 58,52 kJ erforderlich.<br />
