Agas occupies a volume of 20 cubic meters at 9,000 pascals. if the pressure is lowered to 5,000 pascals, what volume will the gas occupy?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

How many neutrons does plutonium -196 with an atomic number of 78.
