Step 1: Draw a model to show how sound is created and how you think it makes the windows move. Step 2: Label your model with explanations. Include all of these science vocabulary/concepts: vibrations/oscillations, force, energy, and transfer.

Step 3: You have to take a piece of paper outside then copy the first pic I put in then fill in the answers then upload the image when done.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
