Note that you will most likely get different numbers for the different parts below. As usual, a good way to handle that is to solve the problem using variables, and only plug in numbers at the end. Part (a) Homework . Unanswered . A cylinder filled with ideal gas is sealed by a piston that is above the gas. The piston is a cylindrical object, with a weight of 40.0 N, that can slide up or down in the cylinder without friction. The area of the top (or the bottom) of the piston is 100 cm2. The top of the piston is exposed to the atmosphere, and the atmospheric pressure is 100 kPa. As shown in the figure, the piston is tied to a string that passes over a pulley system and is tied to a block that has a weight of 90.0 N. Both the block and the piston are in equilibrium. The cylinder has a height of 40.0 cm, and, when the temperature of the gas is 20C, the bottom of the piston is 20.0 cm above the bottom of the cylinder. Calculate the pressure of the gas in the cylinder. kPa . .. . Type your numeric answer and submit Unanswered . 5 attempts left Submit Part (b) Homework .
