Do fluid molecules include solid molecules? Why does a particle move like a wave? What is true about microscopic properties of an object? 1) They are just small versions of the macroscopic properties. 2) They are the properties of particles that make up the object. 3) They are the ...
How do molecules move around? Diffusion is the movement of molecules from a HIGH concentration to a low concentration Whaddaya mean, molecules MOVE ??? You gotta be kidding me! Yeah, right diffusion animation OSMOSIS WATER through a membrane Osmosis is the movement of from a high to a low c...
Note that the ice surface is dirty due to the accumulation of sand and gravel particles. Tazlina Valley Glacier in Alaska is retreating. Image by Bruce F. Molnia, USGS. Click the image to enlarge. Zones of a Glacier: A cartoon cross-section through a glacier, showing the zone of ...
The detector is so gargantuan that a unique transport machine was required to move the 28 200-ton blocks that make it. NOvA analyses how neutrinos change or ‘oscillate’ into different types. Neutrinos leave almost no trace and rarely interact with each other or other particles. The particle ...
(aged 12 to 13) considered the existence of other material such as air between the particles. In terms of the conservation of matter, Hesse and Anderson [39] found that 11-year-old children considered that matter is not conserved in the reactions in which gases are released. Regarding ...
Michelson, along with his colleague Edward Morley, worked under the assumption that light moved as a wave, just like sound. And just as sound needs particles to move, Michelson and Morley and other physicists of the time reasoned, light must have some kind of medium to move through. This ...
It begins to have a hard time maintaining blood pressure and eventually loses its ability to move enough blood around to maintain all the body's essential functions. The Mesentery The primary function of the mesentery, a fold of tissue that attaches to the intestines and other abdominal organs...

The simplest kind of filter is a sieve: something with holes that are big enough to trap some particles and small enough to let others through. Some vacuum cleaners do use filters like this to stop bigger particles of dust and dirt—but how do you catch smaller dirt particles as well?
where there are already no finer materials left. When a steady wind starts to blow, fine particles on the open ground will begin vibrating. As the wind picks up, some of the particles are lifted into the air. When they fall onto the ground, they hit other particles which will then be ...
