Question

Газ совершил работу 18 дж и получил кол-во теплоты 4 дж. Внутренняя энергия газа какая?

Answer 1

Уменьшилась на 14 дж

Answer 2

Calculation of Internal Energy

To calculate the internal energy of the gas, we can use the equation:

U = Q + A (Equation 1)

Where: - U represents the internal energy of the gas - Q represents the amount of heat absorbed or released by the gas - A represents the work done by or on the gas

From the given information, we know that the gas performed work equal to 18 J and absorbed 4 J of heat. We need to find the internal energy of the gas.

Using Equation 1, we can substitute the values:

U = 4 J + 18 J

Therefore, the internal energy of the gas is 22 J.

Conclusion

The internal energy of the gas is 22 J.
