It means at absolute zero tempcrature, the molecules are in a perfect statL of rest and have no kinetic energ'y.

But beforc the absolute zero tempcrature is reached, all gases change their state to liquids and solids. Thus, from equation ;i , thc mean kinetic cnerg'y of a molecule is directly proportional to the absolute tcmperature of a gas. When the tenpe;ture of the gas ir increased, the mean kinetic energy ofl the moleculcs increases. When heat is withdrawn from a gas, the mean kinctic energy of the moleculer decreases- Thus, at absolute.

В его ушах звучали слова Стратмора: Не звони, пока не добудешь кольцо. Внезапно он почувствовал страшный упадок сил. Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно. Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг. Он решил подумать об этом через минуту.

 Так не пойдет! - рявкнул Стратмор, - Мне нужен ключ. - У меня нет никакого ключа. - Хватит врать! - крикнул Стратмор.  - Где. Хейл сдавил горло Сьюзан. - Выпустите меня, или она умрет. Тревор Стратмор заключил в своей жизни достаточно сделок, когда на кону были высочайшие ставки, чтобы понимать: Хейл взвинчен и крайне опасен.

Он перезагрузил монитор, надеясь, что все дело в каком-то мелком сбое. Но, ожив, монитор вновь показал то же. Чатрукьяну вдруг стало холодно. У сотрудников лаборатории систем безопасности была единственная обязанность - поддерживать ТРАНСТЕКСТ в чистоте, следить, чтобы в него не проникли вирусы.
