a. Compute the specific heat capacity at constant volume of nitrogen (N2) gas. The molar mass of N2 is 28.0 g/mol. b. You warm 1.15 kg of water at a constant 1L volume from 20∘C to 30∘C in a kettle. For the same amount of heat, how many kilograms of 20∘C air would you be able to warm to 30∘C? Make the simplifying assumption that air is 100% N2. What volume would this air occupy at  20∘C and a pressure of 1 atm ?

7 of 13 At an altitude of 11,000 m (a typical cruising altitude for a jet airliner), the air temperature is -59.0° C and the air density is 0.467 kg/m³. The molar mass of air is 28.8 g/mol. Part A What is the pressure of the atmosphere at that altitude? (Note: The temperature at this altitude is not the same as at the surface of the earth, so the equation Р— Ро ехp (- Mgy doesn't apply.) RT Express your answer with the appropriate units. HA ?

Problem 5:   n = 3.9 moles of an ideal gas are pumped into a chamber of volume V = 0.094 m3. Part (a)  The initial pressure of the gas is 1 atm. What is the initial temperature (in K) of the gas?  50% Part (b)  The pressure of the gas is increased to 10 atm. Now what is the temperature (in K) of the gas?

A diver observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). The temperature at the bottom is 4.0°C, and the temperature at the surface is 23.0°C. Part A What is the ratio of the volume of the bubble as it reaches the surface to its volume at the bottom? Enter your answer numerically. VE ΑΣΦ V2 V₁ Submit Part B Request Answer Would it be safe for the diver to hold his breath while ascending from the bottom of the lake to the surface? Submit No. This increase in volume of air in the lungs would be dangerous. Yes. This increase in volume of air in the lungs is safe enough for human body. Provide Feedback ? Request Answer

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 =
