reversible.
because you can melt it back to a liquid.

5000 psi air weight density in 10 cubic feet?
5000psi is equal to the pressure at 11,545 ft of water. The density can be found from the equation lbs/ft^3=1.3 x inches-mercury/Abs temp in Rankine. This gives lbs/ft^3= 1.3 x 11545 x 1.13/460 =36.9 pounds ( the 1.13 is to convert inches mercury to ft water ) for 10 cuft that makes it 369 pounds.
Name 11 factors that should be considered when selecting a material for a product?
The temperature in a vessel is 36 degree C and the proportion by mass of air to dry saturated steam is 0.1. What is the pressure in the vessel in bar and in mm of mercury vacuum? The barometric pressure is 760mm Hg
Is the engine a free wheeling engine?
Yes, the Mercury Villager and Nissan Quest engine, 3.0L and 3.3L, are all freewheeling engines at the insistance of Ford to enter into the joint venture program. The Maxima and Pathfinder with the same engine remained non- freewheeling (interference engines). I work for Ford and worked on the Villager program from 1989 to 2002 and was personally involved in the development of this program.
Can metal melt?
Yes, all metals, both pure (element) and alloys, can be melted; though some require large heat inputs at very high temperatures. By contrast the lowest melting point is of a lead-tin-antimony-bismuth mixture called "Wood's Alloy", at about 70ºC.
Is the freezingbof mercury a reversible or irreversible physical change Explain your answer?
Freezing mercury is a physical change. It can be reversed by raising the temperature above the freezing point.
Is the freezing mercury reversible or irreversible physical change?
It is a physical change.
Is the freezing of mercury a reversible or irreversible change?
It's reversible. When you raise the temperature of frozen mercury, it 'melts' back into liquid form (just like ice melts back into water when you warm it).
How is freezing mercury a reversable physical change?
During freezing the chemical nature of mercury remain unchanged.
Is freezing mercury a physical changes?
yes
Is it a physical or chemical change when the liquid mercury in a thermometer expands as it is heated?
physical change
Is the freezing point of mercury or butter closer to the freezing point of water?
Mercury because butter does not freeze. Butter does not have a freezing point. Butter is a fat that solidifies gradually as it gets colder and does not go through a phase change (freezing) abruptly like mercury or water.Although butter will become as solid as it gets at a temperature closer to that of the freezing point of water than the freezing point of mercury.
What had you freeze the mercury?
The freezing point of mercury is -38,829 0C.
Is freezing mercury a change of state?
Yes, freezing anything is a change of state.
Is mercury a meltingpoint or a freezing point?
Both
What is the state of matter of mercury at freezing temperature?
At mercury's own freezing temperature, the mercury can be either solid or liquid; that is the definition of "freezing temperature".
Freezing point of Mercury?
About -39 C. or about -38 F.
