Question

Газ получал количество теплоты 95 Дж и совершил работу 35 Дж.На сколько изменилась внутренняя энергия газа? Она увеличилась или уменьшилась?​

Answer 1

Ответ:

Увеличилась на 60 Дж

Объяснение:

Q=95 Дж    A=35 Дж    ΔU=?

===

ΔU=Q-A=95-35=60 Дж

===================

Answer 2

Calculating Change in Internal Energy of Gas

To calculate the change in internal energy of the gas, we can use the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

Given: - Heat added to the gas, Q = 95 J - Work done by the gas, W = 35 J

Using the first law of thermodynamics: Change in internal energy, ΔU = Q - W

Substitute the given values: ΔU = 95 J - 35 J = 60 J

So, the change in internal energy of the gas is 60 J.

Conclusion

The change in internal energy of the gas is 60 J. Since the heat added to the gas is greater than the work done by the gas, the internal energy of the gas has increased.
