The variables for this experiment include mass, volume, and the materials in the various balls, as well as their densities. In Part I, you will be comparing a table tennis ball and a golf ball. Use the drop-down menus to complete the sentences and identify the independent and dependent variables. In Part I, the independent variable, the one that is intentionally manipulated, is . In Part I, the dependent variable, the one that you measure the response in, is .

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
