【導讀】是兩個均勻系之間的熱交換的平衡，也是動態平衡。熱交換是能量傳遞的一種方式。溫度是決定一系統是否與其它系統處于熱平衡的物理量，溫度與分子的平均動能相聯系，它標志著物體內部分子無規則運動的劇烈程度。按熱力學原理所確定的溫度。開爾文是熱力學溫度單位，定義為水三相點熱力學溫度的1/。是攝氏溫度的單位，符號為℃。它的大小等于開爾文。溫度的數值表示法。借助于某物質的物理參量與溫度的關系，用實驗方法或經驗公式構成的溫標。與相應物理量的函數關系。按溫標定義進行的一組操作獲得溫標。ITS-90國際溫標子溫區間，同一內插儀器由于實現溫。物理化學性質完全相同，且成分相同的均勻物質的聚集態稱為相。等溫壓縮系數三者發生突變的相變稱為二級相變。態轉變為超導態均屬于此類相變。晶體物質從固相向液相轉變時的相變溫度。依靠流體的運動，把熱量由一處傳遞到另一處的現象。一種含鐵量約為%原子百分比的銠鐵合金絲繞制成的溫度計。
