What will be the pressure at the top of a mountain where atmospheric pressure is 0.7 bar and the absolute pressure is 0.5 bar?

8. What will be the pressure at the top of a mountain where atmospheric pressure is 0.7 bar and the absolute pressure is 0.5 bar?

1. 1.2 bar
2. 0.5 bar
3. 0.2 bar
4. 0.7 bar

Answer: A) 1.2 bar

Explanation:

The absolute pressure at the top of the mountain is the sum of atmospheric pressure and the pressure due to altitude. Therefore, Absolute pressure = Atmospheric pressure + Pressure due to altitude = 0.7 bar + 0.5 bar = 1.2 bar.
