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 else can I help you with?
What increase as the average energy of the motion of the particles of matter increase?
The temperature of the substance would increase as the average energy of particle motion increases. Additionally, the pressure exerted by the particles on the walls of the container would also increase.
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 would happen to the atmospheric pressure at the ground if the earth's gravitational force were to increase?
If the Earth's gravitational force were to increase, the atmospheric pressure at the ground would also increase. This is because the increased gravitational force would cause more air molecules to be pulled towards the Earth's surface, resulting in higher atmospheric pressure.
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.
How would pressure change if the area is change the force is kept constant?
If the area decreases, the pressure will increase since pressure is inversely proportional to area when force is constant (Pressure = Force/Area). This means that a smaller area will result in the force being distributed over a smaller area, leading to an increase in pressure.
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 increase as the average energy of the motion of the particles of matter increase?
The temperature of the substance would increase as the average energy of particle motion increases. Additionally, the pressure exerted by the particles on the walls of the container would also increase.
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 increase or decrease net filtration pressure?
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
When the volume of gas decreases would the pressure increase or decrease?
It would increase.
If temperature increase what happens to pressure?
Are you referring to gases?In gases,if the temperature increases then the pressure would also increase.
What would increase a temperature of a substance?
An increase in energy input, such as heat transfer from a heat source or mechanical work, would increase the temperature of a substance. This causes the particles in the substance to move faster, leading to an increase in kinetic energy and temperature.
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
What happen to yield of sulfur trioxide if you increase the pressure and you decrease the pressure?
Increasing the pressure would increase the yield of sulfur trioxide because the reaction involves a decrease in volume. Decreasing the pressure would decrease the yield of sulfur trioxide because the reaction volume would increase.
What would happen to filtration rate if you were to apply pressure to the filtration system?
It would increase
What changes in air pressure would you expect if you carried barometer down a mineshaft?
As you descend down a mineshaft, the air pressure would increase due to the weight of the air above you pressing down. This is because air pressure is directly proportional to the density of the air above a given point. The barometer would register a higher pressure reading as you go deeper into the mineshaft. Conversely, as you ascend back to the surface, the air pressure would decrease, resulting in a lower pressure reading on the barometer.
