Mount fuji is approximately 12389 ft above sea level. The standard hike up the mountain starts at 6600 ft. The atmospheric pressure at different altitudes can be approximated using the following equation P = e^{−h / 7000} where P is in atmospheres and h is in meters. Determine the atmospheric pressure in mmHg at the start of the hike.

The atmospheric pressure at the summit of Mount Fuji on a certain day was found to be 469 mmHg. What is this pressure in atm and pascal units?

Another unit for pressure is bar. Convert 1 atm and 1 mmHg to bar.

A scuba diver is 15 m deep underwater. Given that the atmospheric pressure is 100 kPa and assuming that the density of water is 1.00×10³ kg/m³, calculate the pressure (atm) exerted on the body of the diver. [Useful information: g = 9.81 m/s² and 1 Pa = 1 kg/ms²]

In an experiment, one of the open ends of a glass tube is in a dish filled with mercury while the other end is closed by a stopcock. The distance between the surface of the mercury to the stopcock is 900 mm. At 20 ºC, the height of mercury in the tube is equal to the height of mercury in the dish.

Which image corresponds to the level of mercury in the tube when the temperature is lowered to –50 ºC?

Calculate the pressure of the gas inside the mercury manometer. Assuming the atmospheric pressure is 1.05 atm.

Calculate the pressure of the gas sample in the illustration below given that the atmospheric pressure is 755.5 mmHg.
