Question

В двух цилиндрах под подвижным поршнем находятся водород и кислород.Сравнить работы,которые совершают эти газы при изобарном нагревании,если их массы,а также начальные и конечные температуры равны.

Answer 1

А1=m*R*(T2-T1)/M1 - работа водорода

А2=m*R*(T2-T1)/M2 - работа кислорода

A1/A2=M2/M1=32*1`0^-3/2*10^-3=16

работа водорода в 16 раз больше работы кислорода

Answer 2

Comparing Work Done by Hydrogen and Oxygen During Isobaric Heating

When comparing the work done by hydrogen and oxygen during isobaric heating, it's important to consider the initial and final temperatures, as well as the masses of the gases.

Initial and Final Temperatures: - The initial and final temperatures of the gases are equal, which means that the change in temperature during the process is the same for both hydrogen and oxygen.

Masses of the Gases: - The masses of the gases are not provided in the search results. Without this information, it's not possible to directly compare the work done by hydrogen and oxygen during isobaric heating.

Work Done by the Gases: - The work done by a gas during isobaric heating can be calculated using the formula: \[ W = P \cdot \Delta V \] where \( P \) is the constant pressure and \( \Delta V \) is the change in volume.

Comparison: - Without the masses of the gases, it's not possible to directly compare the work done by hydrogen and oxygen during isobaric heating. The work done by each gas would depend on its individual mass and the specific conditions of the process.

In conclusion, while the initial and final temperatures are equal for both hydrogen and oxygen, without the masses of the gases, a direct comparison of the work done by the gases during isobaric heating cannot be made.

If you have the specific masses of the gases and additional details about the process, I can help you calculate the work done by each gas.
