Answer #1

A) As pressure is kept constant there according to ideal gas law volume is directly proportional to the temperature. Since gas is expanding therefore it's volume is increasing. therefore temperature will also increase. Internal energy of gas is a function of the gas temperature. i.e. Uf > Ui

B) From above explanation Tf > Ti

C) As gas is expanding; Vf > Vi

D) Entropy is measurement of the disturbance in the system. entropy will increase with temperature. Sf > Si

E) Pf = Pi , since pressure is kept constant.

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 cylinder with a piston contains 0.100 mol of nitrogen at 2.00×105 Pa and 320 K . The nitrogen may be treated as an ideal gas. The gas is first compressed isobarically to half its original volume. It then expands adiabatically back to its original volume, and finally it is heated isochorically to its original pressure. A) Find the work done by the gas during the initial compression B) Find the heat added to the gas during the initial compression...
