1. The initial pressure reading on an ocean-faring submarine is 105 kPa at a depth of 0.35 m. The submarine descends and the new pressure reading is 125 kPA. At what depth is the submarine now located? The density of seawater is 1023 kg/m3 . 1B. The area of a hose on the left end is 3.5 x10-3 m3 while the area on the right end of the hose is 3.0 x 10-3 m3 . A liquid will travel a...

The ideal gas law states that PV = NkgT where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant ko is called the Boltzmann constant and has the value kg = 1.38x10-23J/K. A very common expression of the ideal gas law uses the number of moles, n- N/NA (NA is Avogadro's number, NA=6.021023 per mole). PV...

Given: At normal temperature and pressure, the following conversion formulas may be used to convert back and forth between ppm and mg/m3 . mg/m3= [(MW x ppm) / 24.45] or ppm = [(24.45 x mg/m3 ) / MW] MW: molecular weight in g/mole In these equations 24.45 is the volume (in liters) of a mole (gram molecular weight) of a gas or vapor when the pressure is at 1 atmosphere (760 mmHg) and the temperature is at 25°C. When temperature...

A spray can containing a propellant gas at twice atmospheric pressure (202 kPa) and having a volume of 119.00 cm is at 27°C. It is then tossed into an open fire. (Warning: Do not do this experiment; it is very dangerous.) When the temperature of the gas in the can reaches 195°C, what is the pressure inside the can? Assume any change in the volume of the can is negligible. SOLUTION Conceptualize Intuitively, you should expect that the pressure of the gas...
