Challenge Problems
Push your limits with challenges.
Question 1
Given a mercury barometer shows a column height of 760 mm, calculate the air pressure in Pascals. Use the density of mercury (13600 kg/m³) and gravitational acceleration (9.8 m/s²).
💡 Hint: Convert mm to meters when applying the formula.
Question 2
If air pressure at sea level is approximately 101325 Pa, how does the pressure change with altitude to 3000 meters? Assume constant air density of 1.225 kg/m³.
💡 Hint: Use the same pressure formula but adjust the height for altitude.
