The whole reveiw Flashcards
Homogeneous
The same in structure, quality, or kind.
Solubility
The mass of a solute that can dissolve in a given amount of solvent to form a saturated solution at a given temperature.
Density
The amount of mass in a certain unit of a substance (density equals mass divided by volume).
Average Density
The total mass of an object divided by the total volume.
Saturation Solution
A solution in which no more solute will dissolve in a specific amount of solvent at a specific temperature
Particle model
- All substances are made of tiny particles.
- All particles in a pure substances are the same.
- Particles have spaces between them.
- The particles are always in movement.
- The particles in a substances are attracted to one another.
Flow rate
The volume of fluid that passes a point in a pipe or tube in a certain amount of time.
Viscosity
The measure of how fast a fluid will flow; the thickness or thinness of a fluid.
Types of cells
Plant and animal
Difference between plant and animal cells.
Animal cells have a cell membrane, cytoplasm, nucleus, and vacuoles. While plant cells have everything a animal cell has and also has a cell wall, and chloroplasts.
What is the digestive system in order.
Mouth, esophagus, stomach, small intestine, large intestine, out of body.
What are the characteristics of living organisms?
- living organisms need energy
- living organisms respond and adapt to their environment.
- living organisms reproduce
- living organisms grow
- living organisms produce wastes
Selectively membrane
Allowing only certain materials to pass.
Heterogeneous
Made up of parts, or mixed.
Groupings of cells.
Cells-tissues-organs-systems-organisms
What is a permeable membrane?
Allowing materials to pass through.
What is a impermeable membrane?
Allowing no materials to pass through.
How does food and water get transport ed through plants?
Root hairs absorb the water into the roots that then go up the xylem to the rest of the plant. Food gets made in the leaves through the process of photosynthesis and is transported to the rest of the tree via the phloem.
Translucent
Allowing only some light to pass through, and the light that does pass through, is scattered.
Transparent
Allowing light to pass through.
Opaque
Allowing no light to pass through.
Reflection
The casting back of light from a surface.
Refraction
The bending of light when it travels from one medium to another.
What does density have to do with refraction?
When light travels through a more dense medium, it refracts more.
Convex lens.
A lens that is thicker in the middle than the edges; causing light rays to converge
Concave lens.
A lens that is thinner in the middle then its edges, causing light rays to diverge.
What are the parts of the eye?
Ciliary muscle, lens, iris, pupil, cornea, aqueous humour, vitreous humour, retina and optic nerve.
What is WHMIS?
Workplace Hazardous Materials Information System
Near-sighted.
Unable to see distant objects clearly. Double concave lens can fix this.
Far-sighted
unable to see close objects clearly. Can be fixed with a double convex.
Light spectrum
ROYGBIV
What are the 5 types of light?
Incandescent, Fluorescent, Phosphorescent, Chemiluminescent, and Bioluminescent
Frequency
The number of entire cycles completed by a vibrating object in a unit of time. Measured in hertz (Hz).
Amplitude
In a wave, the height of the crest and the depth of the trough.
