PROBLEMS 1.1. In the table below, a number in the top row represents the pressure of a gas in the bulb of a constant-volume gas thermometer (corrected for dead space, thermal expansion of bulb, etc.) when the bulb is immersed in a water triple-point cell. The bottom row represents the corresponding readings of pressure when the bulb is surrounded by a material at a constant unknown temperature. Calculate the ideal- gas temperature T of this material.

Q6
0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. The gas then undergoes an isobaric process to a temperature of 260°C. What is the final volume of the gas, in liters? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

1. a. Derive the following expression for the fractional change in the speed of sound (dv/v) dv 1 dT related to a small change in temperature (dT): Start with the expression for the 2 T YRT M speed of sound related to temperature: v= where y is the ratio of heat capacities (a constant), R is the gas constant and M is the molar mass of the substance. Show enough steps (and words!) so that I can tell what you're doing. b. Use the red equation above to determine what the speed of sound in air at 21.0° C is, given that the speed of sound at 20.0° C is 344 m/s. Check your answer against any reference that has the speed of sound in air at different temperatures. Show your setup, and remember that the speed should not be terribly different! Hint: What temperature units should you be using?
