Answer 2

Pressure Change in Soyuz Spacecraft Cabin

The pressure in the cabin of the Soyuz spacecraft at a temperature of 290K is given as 9.7*10^3 Pa.

To calculate how the air pressure will change with an increase in temperature by 8K, we can use the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature when the volume and the amount of gas are constant. The formula for this relationship is:

P1/T1 = P2/T2

Where: - P1 = initial pressure - T1 = initial temperature - P2 = final pressure - T2 = final temperature

Calculation

Given: - Initial pressure (P1) = 9.7*10^3 Pa - Initial temperature (T1) = 290K - Change in temperature = 8K

Using the ideal gas law formula, we can calculate the final pressure (P2) when the temperature increases by 8K.

P1/T1 = P2/T2

9.7*10^3 / 290 = P2 / (290 + 8)

Solving for P2:

P2 = (9.7*10^3 * (290 + 8)) / 290

P2 ≈ 9.7*10^3 * (298 / 290)

P2 ≈ 9.7*10^3 * 1.0276

P2 ≈ 9.97*10^3 Pa

So, the air pressure in the Soyuz spacecraft cabin would be approximately 9.97*10^3 Pa when the temperature increases by 8K.

Conclusion

Therefore, the air pressure in the cabin of the Soyuz spacecraft would increase to approximately 9.97*10^3 Pa when the temperature is raised by 8K.
