Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
I think it is because hydraulic systems are stronger than pneumatic systems. if you know that is wrong then get an expert. : )
Air pressure is used as ejector for the sand blasting.
Pneumatic system is operated by compressed air while hydraulic system is operated with pressurised hydraulic oil or any type viscous oil. Hydraulic systems can usually produce higher control forces and work under extreme operating conditions. This is the system that is primarily used on aircraft to move control surfaces and engine controls. You can often classify pneumatic systems because they have a pump (gas pump) and hydraulic systems have a piston. That is the difference. Also, pneumatic systems are louder because it is a gas under pressure. 1. By definition, hydraulics is used in controlling or harnessing power with the use of pressurized fluids whereas pneumatics studies how pressurized gases influences mechanical motion or movement. 2. Hydraulics uses an incompressible fluid medium like oil whereas pneumatics uses a compressible gas like air. 3. Hydraulic applications demand greater pressures during operations that reach thousands of pounds per square inch whereas pneumatic applications only require 100 psi pressures more or less. 4. Most hydraulic applications generally use bigger components that pneumatic applications. 5. Hydraulic systems are generally more difficult to operate compared to pneumatic applications

Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.

Fluids, such as gases and liquids, can flow and be compressed due to their ability to be easily deformed under pressure. Examples include air, water, and oil. Fluids are commonly used in hydraulic systems and pneumatic systems where their flow and compressibility properties are utilized for various applications.

Yes - but not mixed. Pneumatic systems have more "give" (gas is compressible). Note that the power brakes on your car consists of both.
Different viscosities of hydraulic fluids are needed to match the operating temperature and pressure requirements of various hydraulic systems. Higher viscosity fluids are suitable for higher temperature and pressure conditions, offering better lubrication and protection for components. Lower viscosity fluids are used in systems with lower temperature and pressure requirements to ensure efficient flow and operation.
Many, many places. Good examples of hydraulic systems include automotive brakes, and the control systems of large aircraft. Pneumatic systems include many types of tools found in an automotive repair shop. Both systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics give high forces with low losses, thanks to the virtual incompressibility of hydraulic fluids. Pneumatics are usually less efficient, though simpler since the "resevoir" in the circuit is the atmosphere. That eliminates return piping and leakage problems.
Meter in and meter out are terms commonly used in hydraulic systems to control the flow rate of fluid. In pneumatic systems, flow control valves such as needle valves or flow restrictors are used to regulate the speed of the air flow. These components are designed specifically for pneumatic applications due to the differences in fluid properties and system requirements between pneumatic and hydraulic systems.
Working fluid. In one it's gas (air) and in the other it's liquid. This is a much bigger difference than it might seem at first, because gases are compressible and liquids, to a very good approximation, are not.

Used in trucks and buses. This type of braking system of pneumatic and hydraulic hybrid vehicles.
Liquid is used in hydraulic systems.
