Using the ideal gas law equation of P=NkT/V, show that: a) a container of gas obeys Boyle's Law, which states that if the temperature of the gas is held constant, the pressure of the gas is proportional to its volume. b) a container of gas obeys Gay-Lussac's which states that, if the volume of a container is held constant, the pressure is proportional to its temperature. c) if the pressure is held constant, the temperature is related to volume. Draw a sketch showing how V varies as a function of T if P is held constant.
Boyle's Law states that pressure exerted by a gas is inversely proportional to its volume at constant temperature. if for a certain gas, the measured parameters are p=0.75 atm and v=8L, then determine how much the volume changes when the pressure exerted is 0.8 atm?
The Joule-Kelvin coefficient that determines the performance of a gas in a throttling process is defined as μ_JK = (∂T/∂p)_H where H is enthalpy. Show that μ_JK= 0 for an Ideal Gas. [HINT: You will need to form an expression for H, and use the differential calculus cyclic relation to correctly form this partial derivative for μJK]
Prove that the Cv of an ideal gas does not depend upon specific volume by showing that: ( SCv/ SV )=T( S2P/ ST2)V. (show the mathematical derivation)NOTE: The S btw is delta S (see picture attach) I can't copy the symbol.
In the simple kinetic theory of a gas we discussed in class, the molecules are assumed to be point-like objects (without any volume) so that they rarely collide with one another. In reality, each molecule has a small volume and so there are collisions. Let's assume that a molecule is a hard sphere of radius r. Then the molecules will occasionally collide with each other. The average distance traveled between two successive collisions (called mean free path) is λ = V/(4π √2 r2N) where V is the volume of the gas containing N molecules. Calculate the mean free path of a H2 molecule in a hydrogen gas tank at STP. Assume the molecular radius to be 10-10 a) 2.1*10-7 m b) 4.2*10-7 m c) none of these.
Suppose the absolute temperature of anideal gas is doubled from 100 K to 200 K. (a) Does the averagespeed of the molecules in this gas increase by a factor that is greaterthan, less than, or equal to 2? (b) Choose the best explanation fromamong the following:I. Doubling the Kelvin temperature doubles the average kineticenergy, but this implies an increase in the average speed by afactor of 22 = 1.414c, which is less than 2.II. The Kelvin temperature is the one we use in the ideal-gas law,and therefore doubling it also doubles the average speed ofthe molecules.III. The change in average speed depends on the mass of the molecules in the gas, and hence doubling the Kelvin temperaturegenerally results in an increase in speed that is greater than afactor of 2.
