Question

Над газом внешние силы совершили работу 300Дж, а его внутренняя энергия увеличилась на 100Дж. В этом процессе газ объясните как делать эти задания

Answer 1

Задача решается через 1 закон ТД
ΔU=A+Q
A- работа внешних сил
ΔU изменение внутренней энергии
Q количество теплоты
Q=ΔU-А=100-300=-200 Дж
количество теплоты отрицательное
газ отдал 200 Дж теплоты  Ответ

Answer 2

Understanding the Problem

In this problem, external forces have done 300 J of work on a gas, and its internal energy has increased by 100 J. We need to explain what happens to the gas in this process.

Answer

When external forces do work on a gas, the gas can either gain or lose energy. In this case, the external forces have done 300 J of work on the gas, which means that the gas has gained 300 J of energy from its surroundings.

At the same time, the internal energy of the gas has increased by 100 J. Internal energy refers to the total energy of the gas, including its kinetic energy and potential energy due to the motion and interactions of its molecules Therefore, the total energy of the gas has increased by 100 J.

To summarize: - External forces have done 300 J of work on the gas, increasing its energy by 300 J. - The internal energy of the gas has increased by 100 J.

Additional Information

It's important to note that the change in internal energy of a gas can be influenced by various factors, such as changes in temperature, pressure, and volume. The relationship between these factors can be described by different laws, such as the ideal gas law or the laws of thermodynamics.
