Please provide a 250 word explanation AND DESCRIPTION OF A REAL WORLD APPLICATION of one of the following topics:

-ideal gases or the ideal gas law

-the gas constant or the Boltzmann constant

-the root mean square speed of molecules in a gas

-molar specific heat

-the mean free path of a gas molecule

Please be descriptive and include example equations if possible. If post meets requirements of 250 words, explanation of theory, AND A REAL WORLD APPLICATION, I will promptly thumbs up. Thank you!

I need to figure out what questions could be asked from these scenarios.

- A snowboarder comes off of a ramp at an angle of theta above the horizontal, with a speed of v. The end of the ramp is a height h above the ground. Neglect friction and air resistance.

- A boy is standing on a ramp that is inclined at an angle theta above the ground. He is not slipping due to a static frictional force of f_s.

- A boy tries to toss a ball of mass m into his toy wagon, which is initially at rest. The ball hits the wagon at a velocity of v, at an angle theta below due east. Instead of staying in the wagon, the ball bounces out of the wagon with a velocity of v_2, at an angle theta_2 above due east. After being hit by the ball, the wagon has a velocity of v_3, due east. Neglect friction.

- A box that is of length l and height h is sitting on a small bench. The combined center of gravity of the box and bench is located a distance d to the right of the left bench support. The box and bench have a combined mass of M.

- A vertical frictionless spring with a spring constant of k is mounted unstrained on the floor. An object of mass m is dropped onto the spring from directly above, compressing the spring by a distance y. Ignore air resistance.

- A fluid of a given density is flowing through a tube that has a single entry and a single exit point. The second half of the tube has a greater diameter than the first half.

- Object 1 has a temperature of T and is placed in thermal contact with Object 2, which has an initial temperature of T_2. Object 2 is twice as massive as Object 1. The two objects eventually reach a thermal equilibrium at a temperature of T_3.

- n moles of a monatomic ideal gas expands adiabatically, and its temperature decreases from T_1 to T_2.

(8%) Problem 3: A 0.275-kg aluminum bowl holding 0.65 kg of soup at 25.0°C is placed in a freezer.What is the final temperature, in degrees Celsius, if 377 kJ of energy is transferred from the bowl and soup, assuming the soup’s thermal properties are the same as that of water? Specifically, you can assume the latent heat of fusion for the soup is 334 kJ/kg.
