(a) What is the average kinetic energy per Argon atom, in Joules (J)? (b) What is the RMS average speed of the Argon atoms, in meters per second (m/s)? (c) What would the temperature of the gas have to be for the RMS average speed to 275 m/s? Give your answer in degrees Celsius (°C).The number density of gas atoms at a certain location in the space above our planet is about 0.75 × 1011 m-3, and the pressure is 2.65 × 10-10 Pa in this region. What is the temperature in this region, in degrees Celsius?When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = πr²p. piston head V x The work done by the gas when the volume expands from volume V₁ to volume V2 is as follows. 1 W = dv In a steam engine the pressure and volume of steam satisfy the equation PV1.4 = k, where k is a constant. (This is true for adiabatic expansion, that is, expansion in which there is no heat transfer between the cylinder and its surroundings.) Calculate the work done by the engine during a cycle when the steam starts at a pressure of 180 lb/in² and a volume of 500 in³ and expands to a volume of 700 in³. (Round your answer to two decimal places.) W = X ft-lb
