everything any other plane does
propeller planes weight depends on how, tall it is, how wide it is, and how much cargo it has.
Yes they are still being used but they are not popular. That answer is true for military airplanes but for civilian airplanes propeller driven airplanes are the MOST flown and more of them are being manufactured than jet planes.

no, there were not jet planes in WW1. However, there were propeller powered biplanes that were used to a great extent in reconnociance.
Where the gun fires through the propeller, the two are mechanically connected and timed so that the rounds will pass between the blades of the propeller.
Yes many jets can travel at this speed as can props
No, because propellers do not power anything. The engines of the planes power the propeller to get the plane propelled through the air.
There are three different types of gases used there is type A which is used for commercial airliners, type B which is used for smaller, and type C which is used for propeller driven planes specifically water planes. While the above may be true, jet fuel is essentially kerosene.

The change in the 1950's to aircraft was propeller driven to jet engines
If you mean "the first plane that had a motor and propeller, and could fly" then it was the Wright Brothers. If you're not worried about the thing being able to fly, there were LOTS of guys who made propeller planes that couldn't fly.
Jet planes are faster than the normal propeller powered airplanes. Jet planes were invented by Sir. Frank Whittle. There are also supersonic Jet planes. Concorde was the fastest Passenger Jet plane.
