An ideal gas is kept under constant temperature inside a piston. Initially, the gas takes up 3 m3 of space, and is under 105kPa of pressure. What is the new volume of the gas if the pressure is increased to 160kPa

Astream that is 3 wt% b and the 97 wt% c, and a stream that contains only a and b (5,300 kg/hr total), are fed to a column. three product streams emerge: the overhead is 100% a. the bottom stream is 60 wt% b and 40 wt% c. the middle stream is 70 wt% a and the rest b and c and flows at 1,200 kg/hr. how many material balances can be written on the overall system?
