Fantastic Fluids

Question 0

Know all of the properties of matter defs.

Answer 0

Solid- the state of matter in which the substance has a decimate shape and volume
Liquid- the state of matter in which a substance has a definite volume but no definite shape
Gas- the state of matter in which a substance has neither a definite shape or volume

Question 1

What are the 5 points of the Particle Theory of Matter

Answer 1

1) all matter is made up of tiny particles
2) all particles in a pure substance are the same. Different substances are made of different particles
3) there is space between the particles
4) the particles are always moving. As the particles gain energy they move faster
5) the particles in a substance are attracted to one another. The strength of the attractive force depends on the type of particles

Question 2

What are the 3 states of matter

Answer 2

Solids, liquids, and gases

Question 3

List and describe the 5 states of a substance(condensation etc).

Answer 3

Condensation-the change from a gas to a liquid
Freezing- the change from a liquid to solid
Sublimation- change from a gas to a solid and vice versa
Vaporization- change from a liquid to gas
Melting- change from a solid to liquid

Question 4

Define fluid and give 3 examples

Answer 4

Fluid-any substance that flows, or takes the shape of its container including liquid and gas

Question 5

Be able to identify fluids from non-fluids

Answer 5

A fluid is something that flows where as non-fluid doesn’t flow it stays in the same place

Question 6

What is density describe in several ways

Answer 6

Density is the amount of mass in a certain substances unit volume or the crowdedness of the particles that make up matter

Question 7

How do we measure the density of a substance what tools are used

Answer 7

Tools we use our a measuring cup or graduated cylinder for liquids or balance for a solid. We have to measure the volume and then measure the mass before we measure the density

Question 8

What Is the formula for density

Answer 8

Formula for density is D equals M divided by V

Question 9

Define mass and volume. What is the unit used to describe each and the instrument used to find each

Answer 9

Mass is the amount of matter in a substance often measured with a balance in kilograms or grams. A balance is used to measure the mass of a substance. Volume is the measurement of the amount of space occupied by an object often measured with a measuring cup or graduated cylinder and leaders are cubic units. A measuring cup and a graduated cylinder are used to measure volume

Question 10

If you were given the density and the volume can you calculate the mass of a substance? how list the formula

Answer 10

The formula is VD equals M

Question 11

Given the density and the mass of a substance can you calculate the volume of that substance? list the formula

Answer 11

The formula is V equals M divided by D

Question 12

What is buoyancy?

Answer 12

Buoyancy is the tendency to float or rise in the fluid

Question 13

What happens to an object when the buoyant force is greater than the gravitational force

Answer 13

The object will float

Question 14

What happens to a object when the buoyant force is less than the gravitational force on the object

Answer 14

It will sink

Question 15

What is the definition of pressure

Answer 15

The force acting a perpendicular to a certain surface area

Question 16

Is the definition of area

Answer 16

The amount of surface

Question 17

What is the definition of force

Answer 17

A push or pull or anything that causes a change in the motion of an object

Question 18

What is the formula for pressure

Answer 18

Pressure equals force divided by area

Question 19

State Archimedes principle and define the displacement of water

Answer 19

Archimedes principle is the scientific principle that states that the buoyant force acting on a submerged object equals the weight of the fluid displaced by the object.
Displacement of water means that the displace takes over the space

Question 20

What is the difference between hydraulic systems and a pneumatic system

Answer 20

Hydraulic systems are devices that can transmit applied forces through a liquid to transport something else because of pressure. Pneumatic systems use pressurized gases instead of water.

Question 21

Give me one of hydraulic system advantage and one disadvantage. Give me one pneumatic system advantage and one pneumatic system disadvantage.

Answer 21

Pneumatic systems use gas which can be compressed. But pneumatic systems use water which cannot be compressed.
Hydraulic systems use water that can be enclosed. But pneumatic systems use gases which can get lost

Question 22

What are two structures that can work by hydraulics

Answer 22

Pipe systems and dentist chairs

Question 23

What are two structures that can work with pneumatics

Answer 23

Large tampers and dentist drills
