In this problem we will examine what the temperature of these various phenomena are. Part (a) Give an expression for the temperature of an ideal gas in terms of pressure P, particle density per unit volume ρ, and fundamental constants. T = ______ Part (b) Near the surface of Venus, its atmosphere has a pressure fv= 91 times the pressure of Earth's atmosphere, and a particle density of around ρv = 0.91 × 1027 m-3. What is the temperature of Venus' atmosphere (in C) near the surface? Part (c) The Orion nebula is one of the brightest diffuse nebulae in the sky (look for it in the winter, just below the three bright stars in Orion's belt). It is a very complicated mess of gas, dust, young star systems, and brown dwarfs, but let's estimate its temperature if we assume it is a uniform ideal gas.

- If the atomic radius of a metal that has the face-centered cubic crystal structure is 0.2718 nm, calculate the volume of its unit cell in nm³.(a) How many silicon atoms are there in each unit cell? (b) How many silicon atoms are there in one cubic centimeter? (c) Knowing that the length of a side of the unit cell (the silicon lattice constant) is 5.43 Å, Si atomic weight is 28.1, and the Avogdaro's number is 6.02 × 10²3 atoms/mole, find the silicon density in g/cm³.In the Taylor Expansion, it looks like they've made x_0 = x_1, x_2 and made x = x_1 - a, x_2 - a. I don't understand how they can use that substitution for x_0 since it is a constant, and x_1 and x_2 are variables that can change.
