Question

As a Boeing 747 gains altitude, the passenger cabin is pressurized. However, the cabin is not pressurized fully to atmospheric (1.01 × 105 Pa), as it would be at sea level, but rather pressurized to 8.72 × 104 Pa. Suppose a 747 takes off from sea level when the temperature in the airplane is 25.0°C and the pressure is 1.01 × 105 Pa.

If the number of moles of air in the cabin does not change, what would the temperature be?

The answer must be in Celsius.

Answer 1

solietion : * From ideal gas equation temperature is proportional to its pressure keeping other paralleler ausaltered directly all together Iz L = P of final temperature T P2 a (273,15 +25)k[ 8.72x10upa 12=1 Pi 11.01x105 Pal 12=287.4k * In degrees > 257.4 K-273,15K => 15.75cl
