- Question A2 An ideal gas occupies a volume of 1.75 cm³ at 30°C and atmospheric pressure. Calculate the number of molecules of gas in the container. (1 atm = 1.013 x 105 Pa)Part C Some hydrogen gas is enclosed within a chamber being held at 200°C with a volume of 0.0250 m³. The chamber is fitted with a movable piston. Initially, the pressure in the gas is 1.50 × 106 Pa (14.8 atm). The piston is slowly extracted until the pressure in the gas falls to 0.950 x 106 Pa. What is the final volume V₂ of the container?

Find the total translational kinetic energy?a A Geiger-Mueller tube is a radiation detector that consists of a closed, hollow, metal cylinder (the cathode) of inner radius r and a coaxial cylindrical wire (the anode) of radius rb (see figure below) with a gas filling the space between the electrodes. Assume that the internal diameter of a Geiger-Mueller tube is 3.05 cm and that the wire along the axis has a diameter of 0.195 mm. The dielectric strength of the gas between the central wire and the cylinder is 1.15 x 106 V/m.
