Question

Газу передано 4*104Дж количества теплоты, его внутренняя энергия увеличилась на 2*104Дж. При этом газ совершил работу равную:

Answer 1

Q=ΔU+A     первое начало термодинамики

A=Q-ΔU=4*10^4-2*10^4=2*10^4 Дж

 

Answer 2

Calculation of Work Done by the Gas

To calculate the work done by the gas, we need to use the equation:

Work (W) = Change in Internal Energy (ΔU) - Heat Transferred (Q)

Given that the heat transferred (Q) is 4 * 10^4 J and the change in internal energy (ΔU) is 2 * 10^4 J, we can substitute these values into the equation:

W = (2 * 10^4 J) - (4 * 10^4 J)

W = -2 * 10^4 J

Therefore, the work done by the gas is -2 * 10^4 J.

Note: The negative sign indicates that work is done on the gas, rather than by the gas.
