Would an increase in pressure cause this substance to freeze or melt?

Corrected: Only with some peculiar
substances like ice contract on melting and expand on freezing. Since pressure also contracts ice, doing the same work of melting, the melting point of ice DECREASES with INCREASE of pressure.
Added:
In 'Related links' attached to this page (lower left corner) a diagram-picture of
"Melting point: Temperature and Pressure" is shown as
Green line for most 'normal' solids
and of
Water-Ice: it is the Green-Dotted line.

What would increase the temperature of a substance?
Increase the pressure (at constant volume) or increase the volume (at constant pressure), or do both at the same time. This is based on the Ideal Gas Law, which says PV = nRT. You can also just apply heat to it!
What effect does an increase in temperature have on a gas's volume and pressure?
As indicated by the Ideal Gas Laws, increasing temperature will tend to increase both volume and pressure. Of course, volume can't always increase, that depends upon the flexibility or inflexibility of the container that the gas is in, and if the volume does increase that will counteract the increase in pressure that would otherwise have happened. Temperature, pressure, and volume are all interconnected in a gas.
What would cause a freeze plug to blow out?
Pressure in the motor building up, using straight water instead of anti freeze, or having a blown head gasket or cracked head would cause a freeze plug to blow out. Better take it to a mechanic and have them look at it.
Does pressure increase or decrease in deep water?
I'm not quite sure, but I would say that pressure does increase as you near the center of the Earth. Some argue that when you reach the center, there would be no pressure because of the equal amount of weight on each side. My question is...is the weight equal on every side. If not, then there would be pressure inside the core of the Earth.
What would cause the pressure in a sealed container of gas to increase?
temperature increase The pressure of a contained sample of gas can be increased by increasing its temperature, or by decreasing its volume, or by injecting additional mass into it.
Is it true that water would never freeze at -4C?
No, pressure affects the freezing point of substances. When you increase the presure, you lower the freezing point. So if you kept water at -4C then increased the pressure enough, the water would start to freeze
What changes in air pressure would you expect if you carried barometer down a mineshaft?
the air pressure would increase because the amount of atmosphere above you increases
When the volume of gas decreases would the pressure increase or decrease?
It would increase.
How cold does it have to be for something to freeze instantly?
Different substances freeze at different temperatures. However all substances would freeze (except helium) at Absolute Zero. The time it takes for the substance to freeze would also depend on the mass and heat content of that substance.
When volume is increased does pressure increase or decrease?
Neither. Volume is independent of mass. Effectively, if you increase the volume of a substance you are moving the particles that comprise that substance apart. Eventually, you would have a gas which expands to fill the volume of its container.
What would happen to filtration rate if you were to apply pressure to the filtration system?
It would increase
Can cooking gas freeze?
Yes, but you would have to get the temperature right down. Propane will freeze at -188'C at atmospheric pressure.
If temperature increase what happens to pressure?
Are you referring to gases?In gases,if the temperature increases then the pressure would also increase.
Would a person freeze on Uranus?
A person would freeze to death, and they would suffocate.
Where is valve located to increase water pressure?
There is no such thing as a valve cannot increase or decrease pressure IT can throttle volume or stop the flow.=One would need a pressure booster pump to increase pressure=
Which of theses would increase the temperature of a substance?
increasing energy
Raising temperature of a gas fixed volume container will change?
it would change the pressure exerted by the gas in the container.
