What is the difference between a Hypothesis and a Theory?
A hypothesis is an idea based on an observation and a theory is an accept plausible gerneral statement as to why things happen.
K H D B C M?
- K = 1000
- H = 100
- D = 10
- B = 1
- D = .1
- C = .01
- M = .001
C = (F-32) / 1.8
F = (C x 1.8) + 32
pH 7 is?
Water! (Has both hydogen & hydroxide ions)
What is diffusion?
The movement of molecules from a grater concentration area to a lower concentration area to create a balance.
What is Osmosis?
It is the diffusion of water across a permeable membrane.
What is concentration gradient?
It is a difference in the concentration of molecules over a distance.
What is dynamic equilibrium?
It is molecules become uniformly distributed.
- 1 - 6 = acidic
- 7 = Water
- 8-14 = basic
How does the temperature effect the rate of osmosis?
A warmer temperature increase the rate of Osmosis, and a colder temperature decreases.
