Question

В процессе изобарного расширения газа была совершена работа , равная 400 Дж.При каком давлении совершался процесс, если объем газа изменился с 0,3 м3 до 600 л.

Answer 1

P=const
V1=0.3 m3
V2=0.6 m3
ΔV=V2-V1=0.3 m3
работа газа равна А=pΔV. работа и изменение объема нам известны
р = А/ΔV=400/0.3=1333.3 Па ну или 1,3 кПа

Answer 2

Calculation of Pressure during Isobaric Expansion

To determine the pressure during the isobaric expansion of a gas, we can use the formula:

P1 * V1 = P2 * V2

Where: - P1 is the initial pressure of the gas - V1 is the initial volume of the gas - P2 is the final pressure of the gas - V2 is the final volume of the gas

In this case, we are given that the work done during the process is 400 J, and the volume of the gas changes from 0.3 m^3 to 600 L.

First, let's convert the final volume from liters to cubic meters: - 600 L = 0.6 m^3

Now, we can substitute the given values into the formula and solve for P2:

P1 * V1 = P2 * V2

P2 = (P1 * V1) / V2

Substituting the values: - P1 = unknown - V1 = 0.3 m^3 - V2 = 0.6 m^3

P2 = (P1 * 0.3) / 0.6

To solve for P2, we need to know the value of P1. Unfortunately, the given information does not provide the initial pressure of the gas. Therefore, we cannot determine the pressure during the isobaric expansion process without additional information.

Please provide the initial pressure of the gas so that we can calculate the final pressure during the isobaric expansion.
