- At what frequency would the wavelength of sound in air beequal to the mean free path of oxygen molecules at 1.0 atm pressureand 0.00C? The molecular diameter is 3.0 * 10-8 cm.arrow_forwardWhen the length L of aclock pendulum is held constant by controlling its temperature,the pendulum’s period T depends on the acceleration of gravity g.The period will therefore vary slightly as the clock is moved fromplace to place on Earth’s surface, depending on the change in g.By keeping track of DELTA T, we can estimate the variation in g fromthe equation T = 2π(L/g)1/2 that relates T, g, and L. A clock with a 100-cm pendulum is moved from a location where g = 980 cm/sec2 to a new location. This increases the period by dT = 0.001 sec. Find dg and estimate the value of g at the new location.arrow_forwardA helium gas is at pressure 1 atm and temperature 0°c. If it's pressure is dropped to it's initial pressure when it's volume is held constant. Calculate the work done by the gasarrow_forward

- A gas is contained in a rigid container of constant volume; the pressure of the gas is also kept constant. If the original rms speed of the gas molecules is 900 m/s, what would be the final rms speed if the number of particles in the gas is doubled?arrow_forwardA mass m of helium gas is in a container of constant volume V. It is initially at pressure P and absolute (Kelvin) temperature T. Additional Helium is added, bringing the total mass of helium gas to 3m. After this addition, the temperature is found to be 2T. What is the final gas pressure?arrow_forwardThe density of helium gas at 0°C is ρ0 = 0.179 kg/m3. The temperature is then raised to T = 170°C, but the pressure is kept constant. Assuming that helium is an ideal gas, calculate the new density ρf of the gas. kg/m3arrow_forward
