Why does cooling rate affect crystal size?

Why does cooling rate affect crystal size? As the rate of cooling increases, crystal size decreases. This means that something which cools very quickly will have smaller crystal formations, and something which cools slowly will have larger crystal formations. This is easily seen in igneous rock, which may cool at variable rates. What factors affect […]

Are we made of waves?

Are we made of waves? Radio waves are obviously waves. Only when we come close do we notice that this object is actually a wave. Summary: With quantum theory, we find a beautiful unification: instead of there being two fundamental entities (particles and waves), there is only one fundamental entity: waves. Does Matter diffract? All […]

What is the function of Nucleous?

What is the function of Nucleous? The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. What function does the nucleolus perform? The nucleolus is a dynamic membrane-less structure whose primary function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. What […]

Do elements in a period share chemical properties?

Do elements in a period share chemical properties? All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the […]

What is the reason that air tanks must be drained?

What is the reason that air tanks must be drained? To prevent too much moisture and oil from collecting, the air tanks must be drained regularly. Air pressure gauges indicate air pressure in the vehicle’s dual service (primary and secondary) air tanks. Safety valves prevent over-pressure of the air brake system. Why must air tanks […]

Can high voltage low current kill you?

Can high voltage low current kill you? No, it’s the current that kills you. It kills you by putting a current signal through your heart, which interferes with its normal operation. The high voltage is necessary to penetrate the skin. How many volts can Denki produce? This move was first used against members of the […]
