Mix And Flow Of Matter

Question 1

What is a fluid?

Answer 1

A fluid is anything that has no fixed shape and can flow. Usually it is a liquid or gas.
No fixed shape: Takes the shape of a container.
Example: Water

Question 2

What is a slurry?

Answer 2

A slurry is a mix of water and a solid in order to transport the solid.
Example: washing dried mud off of the driveway with the hose.

Question 3

What is a pure substance?

Answer 3

A pure substance is made up of one type of matter and has an unique set of characteristics or properties.
Example: Aluminum foil, baking soda, and distilled water are pure substances.

Question 4

What is a mixture?

Answer 4

Mixtures are two or more substances combined together. In a mixture, each substance keeps its properties, but it may be difficult to identify these properties.
Example: sugar in soda and soap.

Question 5

What is a mechanical mixture?

Answer 5

In a mechanical mixture, you can see the different substances that make up the mixture.
Example: soil in mixed vegetables are both mechanical mixtures.

Question 6

What is a heterogenous mixture?

Answer 6

If there are two or materials that are visible within a mixture, it is called a heterogenous mixture.
-are not hidden
Example: soda.

Question 7

What is a homogenous mixture?

Answer 7

• Look as though it has one set of properties.
• Equal amounts of both substances (all parts of the mixture are the same).
• If it doesn’t have any setting of any substances it is made of, then it is called a solution.

Example: Milk

Question 8

What is a solution?

Answer 8

Solutions occur because each particle slips between each other particle and is evenly distributed throughout the entire mixture. A solution looks as though it is all one solutions or mixture.

Example: Ice Tea

Question 9

What is a suspension?

Answer 9

A suspension is a cloudy mixture in which droplets or tiny pieces of one substance are within another substance. If you leave a suspension undisturbed, it’s parts will usually spread out.

Example: Muddy water

Question 10

What is a colloid?

Answer 10

A colloid is also a cloudy mixture but the droplets or tiny pieces are so small that they do not deprecate out easily.

Example: Homogenized milk is a colloid of tiny cream droplets on whey.

Question 11

What is a solute?

Answer 11

A solute is the substance that dissolves in a solvent.
-solute is a solid

Example: Ice tea powder

Question 12

What is a solvent?

Answer 12

A solvent is a substance that does the dissolving to form a solution.
-Solvent = liquid

Example: Water

Question 13

What is concentration?

Answer 13

The concentration of a solution tells you that the amount of solute dissolved in a specific amount of solvent.

Example: 50 g of solute dissolved in the 100 mL of water has a concentration of 50 g/100 mL

Question 14

What is a solvent?

Answer 14

A solvent is a substance and that does the dissolving to form a solution.
-Solvent= liquid

Example: Water

Question 15

What is concentration?

Answer 15

The concentration of a solution tells you that the amount of solute dissolved in a specific amount of solvent.

Example: 50 grams of solute dissolved in the 100mL of water has a concentration of 50g / 100mL

Question 16

What does it mean for something to be unsaturated?

Answer 16

An unsaturated solution is one in which more solute can be dissolved in a specific solvent at the same specific solvent at the same specific temperature.
-Solvent can still dissolve.

Example: When ice tea is if not that tasty and sweet.

Question 17

What does it mean to be saturated?

Answer 17

A saturated solution is one in which no more solute will dissolve in a specific amount of solvent at a specific temperature. (Using the particle theory, the attractive forces between the particles become balanced and no more particles of the solute can be attracted by the particles of the solvent.

Example: When your ice tea is very sweet and there is ice tea powder at the bottom of your glass.

Question 18

What is solubility?

Answer 18

Solubility is the maximum amount of solute you can add to a fixed volume of solvent at a given temperature.

Example: The solubility of the juice crystals would be the maximum amount of juice crystals that you could dissolve in water at that temperature. Every solution has a saturation point at a given temperature.

Question 19

What does it mean to be at a saturation point?

Answer 19

Every solution has a saturation point at a given temperature. This occurs when no more solute can be dissolved in a fixed volume of solvent at that temperature.

Example: When no more sugar can dissolve in water.

Question 20

What is an aqueous solution?

Answer 20

An aqueous solution means that the solvent is water.

Example: water + ice tea powder = aqueous solution

Question 21

What is the particle model?

Answer 21

1. ) All matter is made up of tiny particles.
2. ) The tiny particles of matter are always moving and vibrating.
3. ) The particles in matter may be attracted to each other or bonded together.
4. ) The particles have spaces between them.

Question 22

What is the viscosity?

Answer 22

How quickly fluids flow is a property called viscosity. It is determined by a fluids internal resistance or friction that keeps it from flowing. The higher the viscosity, the slower the liquid travels.
Friction = up -> Viscosity = up

Example: Syrup has a bigger viscosity than water.

Question 23

What is density?

Answer 23

Density is the amount of matter in a given volume.

Example: A cement brick is more dense than a cardboard box.

Question 24

What is buoyancy?

Answer 24

Buoyancy is the tendency of an object to float when placed in a fluid.

Example: hot air balloon

Question 25

What is compressibility?

Answer 25

When a force pushes on an object, the object is said to be under compression. Objects under compression tend to deform in shape.

Example: When you kick a soccer ball, the force of your foot compresses the ball in temporarily deforms it.

Question 26

What is pressure?

Answer 26

Pressure is the amount of force applied to a different area. It is measured in pascals.

Example: When you push on a wall

Question 27

What is pascals law?

Answer 27

Pascals law is when pressure is applied to a liquid in a container, the pressure and force is transmitted equally and undiminished throughout the liquid; and enclosed liquid transmits pressure equally in all directions.

Example: Bathing in a bathtub

Question 28

What is an hydraulic system?

Answer 28

A hydraulic system is something that uses a liquid under pressure to move loads.

• Device that uses liquids in a confined space to transfer forces.
• Works according to pascals law.

Question 29

What is a pneumatic system?

Answer 29

A pneumatic system is a system that uses gases under pressure to move loads.

• Device that uses gases in a confined space to transfer forces
• Works according to Pascals law.

Question 30

What is that detergent?

Answer 30

A detergent is a substance that can remove dirt from fabric.

Example: Washing clothes

Question 31

What is the pump?

Answer 31

A pump is it device that moves of fluid through or into something.

Example: Water pump to bring down water from the sink.

Question 32

What is the valve?

Answer 32

Valves are important of any system for moving fluid’s. They are devices to control or regulate the amount of flow.

Example: Like the valves in your bathroom taps.
