Решение. Для решения необходимо использовать уравнение Клаузиуса Клапейрона:

Молекулярная масса олова 119.

ж = 6,988 г/см3.

тв, учитывая, что Qпл = 7,2 кДж/моль и r

Найти плотность твердого олова r

 (1/2-00). Зависимость температуры плавления Sn от давления (в бар) передается выражением: t(`С) = 231,8 + 0,0032(P 1).
