Question

A Tank of Helium
A tank used for filling helium balloons has a volume of 0.300 m3 and contains 2.25 mol of helium gas at 20.4°C. Assume the helium behaves like an ideal gas.
(a) What is the total translational kinetic energy of the gas molecules?
SOLUTION
Conceptualize Imagine a microscopic model of a gas in which you can watch the molecules move about the container more
rapidly as the temperature increases. Because the gas is monatomic, the total translational kinetic energy of the molecules is th
internal energy of the gas.
Categorize We evaluate parameters with equations developed in the preceding discussion, so this example is a substitution v
problem.
Use the following equation with n = 2.25 mol and T = 294 K (Give your answer in J):
Eint =nRT =
(b) What is the average kinetic energy per molecule?
SOLUTION
Use the following equation (Give your answer in J):
EXERCISE

Q2. Consider a piston-cylinder device that contains liquid water at 1 MPa and 150 °C. The weights on top of the piston are removed one by one so that the pressure inside the cylinder decreases gradually (Fig. 3–18). Draw a property diagram that shows all the water states including phase change processes, which will go from compressed liquid to super-heated vapor while keeping the temperature constant in the system. P = 1 MPa T = 150°C Heat

You are learning to play the violin. One end of the string is vibrating from the bow running along one end. The other end is tied down. The length of the string we will be looking at is 30 cm and the total mass of the string is 0,32 g. We will be modeling this as a standing wave on a string. You being to play the violin and play a note which has a frequency of 440 Hz. You (having incredible eyesight) see that there are 3 anti-nodes on the string forming a perfect sinusoidal wave (shown in diagram). L i) What is the wavelength of this standing wave? ii) What is the speed of the traveling waves that make up this standing wave? iii) What is the tension of the string? iv) Suppose you increase the tension of the string until you get a new standing wave. Will this standing wave have two antinodes or four antinodes? Explain. (You are still at a frequency of 440 Hz)
