An insulated bottle contains 1 mole of hydrogen gas at P=1 atm and T=300K. Using a magic wand, you order all covalent bonds in the H2 molecules to break instantly. Assume that the magic wand supplies precisely the amount of energy necessary to br eak the bond in every molecule and makes them chemically inert (so they cant recombine) but does not affect the hydrogen otherwise. When the new equilibrium is established, a) What is the new temperature of the...

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...

The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed=√3RTM where R=8.314 J/(mol⋅K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram‑meter squared per second squared (kg·m2/s2). What is the rms speed of Cl2 molecules at 471...

A gas of N hydrogen molecules will have a thermal energy of how much________ NkBT. (Hint: Use the quantum model) 2. Suppose I have a block of matter with 4 two-state “Degrees of Freedom” (bins in which to place energy that can only hold 1 energy packet). How many distinct ways are there to distribute the energy? 3. The free energy...

Neon gas (a monatomic gas) and hydrogen gas (a diatomic gas) are both held at constant volume in separate containers. Each container contains the same number of moles n of each gas. You find that it takes an input of 300 J of heat to increase the temperature of the hydrogen by 2.50°C. Part A How many modes does a single hydrogen gas molecule have? (Assume the vibrational modes are "frozen out"). 3, all rotational kinetic 6, 3 translational kinetic...

A cylinder contains 1.5 moles of ideal gas, initially at a temperature of 113 ∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 6.4×105Pa on the gas. The gas is cooled until its temperature has decreased to 27∘C. For the gas CV = 11.65 J/mol⋅K, and the ideal gas constant R = 8.314 J/mol⋅K. 1.Find the work done by the gas during this process. 2.What is the change in the internal (thermal) energy of...

Rectangular PV Cycle A piston contains 260 moles of an ideal monatomic gas that initally has a pressure of 2.61 × 105 Pa and a volume of 4.9 m3. The piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir. 1. The pressure of the gas is increased to 5.61 × 105 Pa while maintaining a constant volume. 2....
