Sistema holatini o‘zgartirish - Changes of state of a system - In the
approach through equilibrium states of the system, a process can be described
in two main ways. In one way, the system is considered to be connected to
the surroundings by some kind of more or less separating partition, and
allowed to reach equilibrium with the surroundings with that partition in
place. Then, while the superlative character of the partition is kept
unchanged, the conditions of the surroundings are changed, and exert their
influence on the system again through the separating partition, or the
partition is moved so as to change the volume of the system; and a new
equilibrium is reached. For example, a system is allowed to reach
equilibrium with a heat bath at one temperature; then the temperature of the
heat bath is changed and the system is allowed to reach a new equilibrium; if
the partition allows conduction of heat, the new equilibrium is different from
the old equilibrium.
