Fluids- Chemistry

A system that uses pressurized gases to do the work, e.g bike pumps, pressure gauges.

A system that uses pressurized liquids to do the work, e.g, lifts for moving goods, car vehicle systems.

A pump, a valve, a conductor, and a pressure gauge

Pressure refers to the force applied to a unit of surface area. P= force/unit area

We measure pressure in pascals. (Pa). 1 Pa = 1 Neuton per meter squared.

that a force applied to a fluid is distributed equally throughout the fluid.

All matter is made of particles. Particles have space between them. Particles are always moving. Particles move faster and get farther apart when heated. Particles are attracted to each other. All Particles of the same substance are identical.

That the buoyant force on an object immersed in a fluid is equal to the weight of the fluid that the object displaces.

The force exerted by the atmosphere. It decreases the higher you ascend, because there is less air pressing you down.

The force exerted by water. Presses on all parts of your body and in all directions

Mass divided by volume.

Density of object divided by the density of the fluid multiplied by 100.

Fish and some aquatic plants have bladders containing air that can be inflated or deflated, and and ships have features and ballasts that act as weights.

Keep the fluid moving in the desired direction and time.

Forces fluids through a system.

provide a pathway to carry the fluid.

Monitors pressure within the system.

The ability of a substance to become more compact when squeezed.

The ship is hollow, so the air inside it, which has a very low density, it brought the overall density down.
