What is the effect of change in pressure in melting point?
Putting a substance under pressure increases its melting point because substances expand as they melt. Putting them under pressure makes it harder for them to expand, which means that they require more energy (heat) in order to transition from a solid state to a liquid state. If a substance is under pressure, decreasing the pressure will lower its melting point.
Does melting point changes from altitude to altitude?
Yes, it does. It is do because with change in altitude their is change in temp. and pressure which also changes the melting point. The change in melting point could be small to large depending upon change in conditions at different altitudes.
As altitude increases how does air pressure change?
Increased altitude means decreased air pressure.
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
How does air pressure change as air is heated?
Air pressure decreases.But when air gets colder it increases.

Does an increase in pressure make magma cool?
Pressure does not change the temperature of rocks, but it does change the melting point. A rock that is under a lot of pressure, even if it is very hot, will stay solid, even if that same rock at the same temperature under lower pressure would be melted. This happens because intense pressure can hold the structure of the minerals together more easily, in a more solid form.So, with an increase in pressure, the melting point of a rock also increases.
What is the effect of temperature change on the pressure of a contained gas?
When temperature increases, pressure also increases.
How does air pressure change as you move up in the atmosphere?
the air pressure increases
How does air pressure change as you move up the atmosphere?
the air pressure increases
How does water pressure change as you go deeper?
Water pressure increases as you go deeper.
Does melting point changes from altitude to altitude?
Yes, it does. It is do because with change in altitude their is change in temp. and pressure which also changes the melting point. The change in melting point could be small to large depending upon change in conditions at different altitudes.
What causes sedimentary and igneous rocks to change?
by melting and cooling
How does the pressure change when the total volume is increased to 20.0L?
If the total volume increases, then the pressure decreases.
As altitude increases how does air pressure change?
Increased altitude means decreased air pressure.
How does melting point change as the number of carbon- carbon double bonds increase?
As the number of carbon-carbon double bonds increases, the melting point decreases.
Does melting point change from altitude to altitude?
The melting point of a substance does change with altitude. All due to atmospheric pressure, makes different elements behave differently.
