a. Explain what the temperature of an ideal gas actually measures, molecularly b. You have two containers, the first with 1 mole of helium and the second with 5 moles of neon at the same temperature. Which gas has more thermal energy? Explain.

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? Assume that no gas escapes and that the temperature remains at 200°C. Enter your answer numerically in cubic meters. ► View Available Hint(s) V₂ = Submit [5] ΑΣΦ ? m³

Estilos Edición P5. A rigid container contains water vapor at 250°C and an unknown pressure. When the container cools to 150°C, the vapor begins to condense. Estimate the initial pressure in the container. Plot the thermodynamic process on a phase diagram. Answer: 600 kPa.

An ideal diatomic gas initially has a pressure of 5 2.00x10^5Pa, a volume of 4.00m^3 and a temperature of 27 C . It has an adiabatic change in pressure to 6.00x10^5 Pa. a. What are the new volume and temperature? b. What is the change in internal energy of the gas?

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. Use the equation 2πrle in to calculate the maximum potential difference that can be applied between the wire and EO the cylinder before breakdown occurs in the gas. Cathode Anode =
