【導(dǎo)讀】是兩個均勻系之間的熱交換的平衡，也是動態(tài)平衡。熱交換是能量傳遞的一種方式。溫度是決定一系統(tǒng)是否與其它系統(tǒng)處于熱平衡的物理量，溫度與分子的平均動能相聯(lián)系，它標(biāo)志著物體內(nèi)部分子無規(guī)則運(yùn)動的劇烈程度。按熱力學(xué)原理所確定的溫度。開爾文是熱力學(xué)溫度單位，定義為水三相點(diǎn)熱力學(xué)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(shù)值表示法。借助于某物質(zhì)的物理參量與溫度的關(guān)系，用實(shí)驗(yàn)方法或經(jīng)驗(yàn)公式構(gòu)成的溫標(biāo)。與相應(yīng)物理量的函數(shù)關(guān)系。按溫標(biāo)定義進(jìn)行的一組操作獲得溫標(biāo)。ITS-90國際溫標(biāo)子溫區(qū)間，同一內(nèi)插儀器由于實(shí)現(xiàn)溫。物理化學(xué)性質(zhì)完全相同，且成分相同的均勻物質(zhì)的聚集態(tài)稱為相。等溫壓縮系數(shù)三者發(fā)生突變的相變稱為二級相變。態(tài)轉(zhuǎn)變?yōu)槌瑢?dǎo)態(tài)均屬于此類相變。晶體物質(zhì)從固相向液相轉(zhuǎn)變時的相變溫度。依靠流體的運(yùn)動，把熱量由一處傳遞到另一處的現(xiàn)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(jì)。
