Question

Происходит ли изменение внутренней энергии газа при его расширении?

Answer 1

При расширении совершается работа
значит расходуется внутренняя энергия
ОТВЕТ да

Answer 2

Does the internal energy of a gas change when it expands?

When a gas expands, its internal energy can change. According to the first law of thermodynamics, the change in internal energy of a gas is given by the equation:

$$ \Delta U = Q - W $$

Where: - ΔU represents the change in internal energy, - Q represents the heat added to the system, and - W represents the work done by the system.

The internal energy of a gas can increase or decrease depending on the amount of heat added to the system and the work done by the system during expansion.

In summary, the internal energy of a gas can change when it expands, and this change is influenced by the heat added to the system and the work done by the system
