- A gas is confined in a 0.47-m-diameter cylinder by a piston, on which rests a weight. The mass of the piston and weight together is 150 kg. The local acceleration off gravity is 9.813 m s-2, and atmospheric pressure is 101.57 kPa. to What is the force in newtons exerted on the gas by the atmosphere, the piston, and the weight, assuming no friction between the piston and cylinder? (b) What is the pressure of the gas in kPa? (c) If the gas in the eylinder is heated, it expands, pushing the piston and weight upward. If the piston and weight are raised 0.83 m, what is the work done by the gas in kJ? What is the change in potential energy of the piston and wejght?A thin walled hollow aluminium cube 1.442m on a side contains 19.2kg of oxygen gas (o2) at 0 degrees C. The molar mass of oxygen gas is 32u. The volume coefficient of expansion, beta, for aluminum is 75x10-6/ degrees C. a) How many moles of oxygen are in the cube? b) what is the absolute pressure inside the cube? (first work out the volume of the cube). express your answer in atmospeheres (1 atm= 1.013x105N/m2) c) If you plae the cube in the over ( a large oven) raise its temp to 250 degrees C what is the volume of the hot cube? Use the formula for expanison V=Vo(1+beta delta T) d) what is the pressure of the oxygen in the warm, expanded aluminum cube? Assume the oxygen is also now at 250 degrees C. Express answer in atmospheres.A pipe transports gas up a hill. At the bottom of the hill, the mean velocity in the pipe is 10m/s and the pressure is 200Pa. The pipe is then raised 10m to the top of the hill, where the pressure is now measured to be 50Pa. Find the velocity at the top of the hill. The density of the gas is 1.1kg/m^3, and the acceleration due to gravity is 9.81m/s^2
