Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary as the temperature rises. Suppose a mercury thermometer contains 3.380 g of mercury and has a capillary that is 0.200 mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0C to 25.0C? The density of mercury at these temperatures is 13.596 g/cm^3 and 13.534 g/cm^3, respectively.

If a scuba diver descends too quickly into the sea, the internal pressure on each eardrum remains at atmospheric pressure, while the external pressure increases due to the increased water depth. At sufficient depths, the difference between the external and internal pressures can rupture an eardrum. Eardrums can rupture when the pressure difference is as little as 35 kPa. What is the depth at which this pressure difference could occur? The density of seawater is 1025 kg/m3. 1)sketch (include everything in the system) 2)solution(step by step)
1. Given an air with a known temperature and pressure of 4 degree Celsius and 105 KPa, respectively, find the density of the air. 2. A rigid container is closed at one end and measures 7 inches diameter by 14 inches long. The container is held vertically and is slowly moved downward until the pressure in the container is 16.5 psia. What will be the depth of the water surface measure from the free water surface?
A soccer referee inflates a soccer ball to the standard required measured pressure for a game of 90kPa, before the game. The balloon has an internal volume of 2650 cm3 and the air is at a temperature of 25°C when the balloon is first inflated. The ball is brought onto the field of play, and by the time the game starts, the air temperature has dropped to 0°C. Assuming that the volume of the ball does not change significantly, determine the following: a. The amount of heat transferred from the air to the ball during the process.b. The initial pressure to which the balloon must be inflated so that it is at the required measured pressure of 90kPa when it reaches a temperature of 0°C.
2. A spherical balloon containing Oxygen (initially at sea level) has a diameter of 8in. If the uniform density of air is 0.07498lb/ft3 and that the pressure at sea level is 14.7psia, determine the new diameter (inch) of the balloon if it has been brought above sea level by 6000ft. Draw a figure or FBD that will support the problem. Explain each step by step formula.

In medical work, pressures are often measured in units of mm of H2O because body fluids, including the cerebrospinal fluid, typically have nearly the same density as water. The pressure of the cerebrospinal fluid can be measured by means of a spinal tap. A hollow tube is inserted into the spinal column, and the height to which the fluid rises is observed. If the fluid rises to a height of 160 mm, we write its gauge pressure as 160 mm H2O. (a) Express this pressure in pascals, in atmospheres, and in millimeters of mercury.

In other cases, a physician may suspect that a tumor or other growth is locking the spinal column and inhibiting the flow of cerebrospinal fluid. Such conditions can be investigated by means of the Queckensted test. In this procedure the veins in the patient’s neck are compressed, to make the blood pressure rise in the brain. The increase in pressure in the blood vessels is…
The density of mercury changes approximately linearly with temperature as ρ=851.5-0.086T in lbm/ft^3 (T in degrees F), so the same pressure difference will result in a manometer reading that is influenced by temperature. If a pressure difference of 14.7 lbf/in^2 is measured in the summer at 95F and in the winter at 5F, what is the difference in column height between the two measurements?
