A400 liter tank, (labeled a), contains argon gas at 250kpaand
30 degreesc. a cylinder(labeled b), is connected to tank(a) with a
pipe that has a valve that is closed. cylinder b, having a
frictionless piston of such mass that apressure of 150kpa will
float it, is initially empty. the valve isopened and argon flows
into cylinder b and eventually reaches auniform state of 150kpa and
30 degreesc throughout. what is thework done by the argon?

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
