- давление, вызываемое паром. Если пар содержится герметично над жидкостью или твердым телом так, что он может накапливаться над веществом при постоянной температуре, то давление пара достигает максимума, называемого давлением насыщенного пара. Примечание. Для специфической жидкости или твердого тела при постоянном объеме пара над ними давление пара зависит только от температуры.
