At points A, B C and D calculate the absolute pressure. (Patm=96 kPa, γwater=9810 N/m3 )
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...
The volume and pressure of a gas are 4.30 m3 and 2.10 atm, respectively. (a) If this gas expands to two and one-half its initial volume while the pressure is constant, determine the work done on the gas. (b) On the other hand, if this gas is compressed to one-fourth its initial volume while the pressure is constant, determine the work done on the gas.
