*15 points* Please please help You have some Argon gas inside a piston and cylinder apparatus. The number of particles is
constant. Assume the movable piston is free to move up and down. The gas is at a constant
temperature with no heat being added or taken away.
When the piston moves up, what happens to the volume and pressure of the gas?
When the piston moves down, what happens to the volume and the pressure of the gas?
What gas law does this scenario best illustrate? Name it

What is the number of atoms in 3.54 mol s

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
