ch 10 4b Review I Constants Periodic Table The ideal gas law (PV = nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. When n and V are fixed, the equation can be rearranged to take the following form where k is a constant: Part B At standard temperature and pressure (0 C and 1.00 atm), 1.00 mol of an ideal gas occupies a volume of 22.4 L What volume would the same amount...
A process has been proposed whereby an ideal gas is taken from P=10 bar and T=300 K to P=1 bar and T=500K in a closed system. During the process the system performs 1,000 [J] of work and receives 6,430 [J] of heat from the surroundings at a constant temperature of 300 K. The constant pressure heat capacity of the gas cp=30 [J/(mol K)] . Gas constant R=8.314 [J/(mol K)]. (a) (7 pts.) What is the change of molar internal energy...
The ideal gas law (PV=nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. Fix n and V When n and V are fixed, the equation can be rearranged to take the following form where k is a constant: PT=nRV=k or (PT)initial=(PT)final This demonstrates that for a container of gas held at constant volume, the pressure and temperature are directly proportional.The relationship is also called Gay-Lussac's law after the French chemist Joseph-Louis Gay-Lussac, one of...

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...
