in low pressure environments it is possible for a solid to change to a liquid
No, the pressure at the bottom of a tank of fluid is directly proportional to the height of the fluid above that point and the density of the liquid, according to the hydrostatic pressure formula. It is not directly proportional to the density of the liquid alone.
What you do and talk about with him when you two are alone depends on how comfortable you are. He should never pressure you into doing or saying something that you are not comfortable with.
No, high pressure alone cannot change an igneous rock into sedimentary rock; however, the reverse is true. High pressure can change sedimentary rock into igneous rock.
Pressure can't be determined from volume alone. You need more info like temperature, gas amount, or system type (gas, liquid, compression).
Charles Lindbergh flew alone across the Atlantic Ocean. That is something that nobody has ever done
to make the form, nature, content, future course, etc., of (something) different from what it is or from what it would be if left alone
Something that connot be seen with the eyes alone is a protist??
Very little. When using propane the liquid is constantly being converted to the vapor that is used. When the liquid that weighs $.24 pounds per gallon is gone the vapor will last only a short time.

Sure. The water pressure is mainly dependent on the difference in elevation between the reservoir and the user. So elevating the reservoir nominally increases the pressure available to a fixed user.In practice, however, in large municipal water systems, the distribution isn't by gravity feed alone, and the pressure is maintained by controlled pumps..
to work alone independency and under pressure
At a certain temperature, Steel becomes liquid. And I suppose it is even a solution as Steel is an alloy of metals, Not only Iron alone.
