A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 3.00 L and the pressure is initially 105 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 65.0 J of work is then done on the piston, compressing the gas (in other words, the gas does −65.0 J of work). The work is done very slowly so that the gas maintains a...

A certain amount of chlorine gas was placed inside a cylinder with a movable piston at one end. The initial volume was 3.00 L and the initial pressure of chlorine was 1.64 atm . The piston was pushed down to change the volume to 1.00 L. Calculate the final pressure of the gas if the temperature and number of moles of chlorine remain constant. Enter a numerical answer only, in terms of atm. Please show all work

A 19.0-L volume of an ideal gas in a cylinder with a piston is at a pressure of 2.8 atm. Enough weight is suddenly removed from the piston to lower the external pressure to 1.4 atm. The gas then expands at constant temperature until its pressure is 1.4 atm. Find the change in enthalpy, ?H, for this change in state. Express your answer using two significant figures. Find the heat, q, associated with this change in state. Express your answer...
