Explanation:
when magma cools Crystal's form because the solution is super saturated with respect to some minerals if the magma cools quickly the crystals do not have much time to form hence they are small and also the resulting rock is fine grained
Answer:
Explanation:
Given
Pipe is lowered to the water 
Negative Pressure is applied to raise the water
Pressure is given by

where 




(b)8.82 atm is much lower than the vapor pressure of water
(c)The fact of applying a negative pressure of 8.74 below the vapor pressure of water
The electrons are already there. They are freely moving through the conductor.
If the resistance in a circuit remains constant and the current increases, then the power will increase. <em>(A)</em>
In fact, it'll increase as fast as the <em><u>square</u></em> of the current ! Like, if the current somehow increases to 3 times as much, the circuit will start using <u><em>9 times</em></u> as much power as it did before.
