A cylinder with a movable piston holds 2.75 mol of argon at a constant temperature of 285 K. As the gas is compressed isothermally, its pressure increases from 101 kPa to 121 kPa. Find (a) the final volume of the gas, (b) the word done by the gas, and (c) the heat added to the gas. I understand how to do (a) and how to do (c) once I have (b) but I don't get how to do part (b) considering this is an algebra based class.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

not too sure thinking all accelerations are pointed down
