Question

Внутренняя энергия газа увеличилась на 29 Дж при подведении к нему 44 Дж.определить работу,совершенную газом.

Answer 1

 Из первого начала термодинамики A=Q-dU=44-29=15 Дж

Answer 2

Calculation of Work Done by the Gas

To determine the work done by the gas, we need to know the change in internal energy of the gas and the heat added to the gas. In this case, the internal energy of the gas increased by 29 J when 44 J of heat was added to it.

The work done by the gas can be calculated using 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:

ΔU = Q - W

Where: - ΔU is the change in internal energy of the gas - Q is the heat added to the gas - W is the work done by the gas

Given that ΔU = 29 J and Q = 44 J, we can rearrange the equation to solve for W:

W = Q - ΔU

Substituting the values, we get:

W = 44 J - 29 J = 15 J

Therefore, the work done by the gas is 15 J.
