The factors which would qualify the system is thermodynamic system.
The way it relates to the elasticity of the collision.
Explanation of Solution
In
However, at the microscopic level, i.e. the properties of the individual particles then one can apply thermodynamics.
One can relate this to collision theory which considers two kinds of collisions the elastic and the in-elastic collisions. Practically, all collisions are in-elastic because some heat energy is always lost during the interaction and in those cases the behaviour of particles becomes uncertain and cannot be predicted.

- An altitude of 150 km is the lowest altitude where a satellite could successfully orbit the earth.At 150 km, the pressure is about 3 x 10-6torr and the temperature is roughly 250 K. Assuming, forsimplicity, that the air consists entirely of oxygen, calculate the mean free path under theseconditions. What is the average collision frequency?arrow_forwardCould you sketch a distribution function of gaseous with respect to liquid water as a function of temperature (no formula, just a sketch)arrow_forwardHow much work do we have to do (in J, at a constant temperature) to atomize a liquid with a volume of 1 dm3 if droplets of the same size are formed during atomization? For simplicity, assume that the droplet is cube-shaped with an edge length of 1000 nm and a surface tension of 50 mJ / m2.arrow_forward
- Consider the following figure: V1 TL TR V2 Assume that a particle bounces normally off a heated surface with a kinetic energy that is in thermal equilibrium with the surface temperature regardless of its approach energy. Show that average force F produced on the left-hand plate by a single molecule of mass m in bouncing back and forth is: k F = (TRTL)"/2 You will use following information as guide you in your derivation: (number of collisions 1.00s mvz+mv1 (1) F = |(change in momentum of wall) second round-trip time 1.00 s (2) The kinetic definition of temperature: kT = ; mvž 2 2arrow_forwardA mixture of ice and water, or an ice bath, can be used as a reference for thermometers, because it is able to maintain a constant temperature for a substantial period of time. Imagine a cup, consider it massless, with a total amount of 450-g of a 40-60 (by mass) ice-water mixture in thermal equilibrium. What mass of iron of 370 K could I drop into it (given the cup is large enough), before the temperature will start to rise?arrow_forwardQuestion 2: Suppose a solid contains 3 identical independent one dimensional oscillstors and sar i.e. 0, 1 and 2, then- he only the ee td mer O there is only one macrostate with total energy zero. o there are two macrostates with total energy zero.

- Statistical Physics This is the chemical potential of an ideal gas. The second image is the answer to 4.20 problem. Please generate a solution for this problem (to validate the given answer). Thank you!arrow_forwardThe derivation of the ideal-gas equation included the assumption that the number of molecules is very large, so that we could compute the average force due to many collisions. However, the ideal-gas equation holds accurately only at low pressures, where the molecules are few and far between. Is this inconsistent? Why or why not?arrow_forwardA rocket is designed to produce 5 MN of thrust at sea level (assume ambient pressure of 0.1 MPa). The pressure in the combustion chamber is 7 MPa and temperature 2800 K. If the working fluid is assumed to be an ideal gas at room temperature with properties of N2 gas at room temperature (molecular weight 28 kg/kmole). Determine specific impulse, mass flow rate, characteristics velocity and throat diameter.(Take R=8314 J/kmole-K, specific heat ratio 1.4 and nozzle exit pressure as 0.1 MPa)arrow_forward
- 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.arrow_forwardPlease help me in a step by step solution for problem #10?arrow_forwardThe pressure gauge on a cylinder of gas registers the gauge pressure, which is the difference between the interior pres- sure and the exterior pressure P. Let's call the gauge pres- sure P, When the cylinder is full, the mass of the gas in it is m, at a gauge pressure of P. Assuming the temperature of the cylinder remains constant, show that the mass of the gas remaining in the cylinder when the pressure reading is P is given by P + P = N. Р. + P.arrow_forward
