Bod topenia medi je kritick\u00fd rovnov\u00e1\u017eny stav. Ozna\u010duje prechod z pevnej l\u00e1tky do kvapaliny. T\u00e1to premena prin\u00e1\u0161a v\u00fdznamn\u00e9 zmeny v \u0161trukt\u00fare kovov a chemick\u00fdch l\u00e1tok. Zvy\u010dajne sa vyjadruje v \u00b0C a \u00b0F.<\/p>\n\n

R\u00f4zne zliatiny medi v\u0161ak maj\u00fa r\u00f4zne teploty topenia v z\u00e1vislosti od ich zlo\u017eenia.
