How does melting point of bromine change with external pressure?

Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].

What causes sedimentary and igneous rocks to change?
by melting and cooling
What do you call it when you change ice to water?
The change from ice to water is a physical change defined as melting, this reaction occurs when ice exceeds a temperature of 32 degrees Fahrenheit (0 degrees Celsius.)
What is the color change between aqueous bromine and sodium chloride?
There will be no colour change between the two, as chlorine is more electronegative than bromine and will maintain its negative charge, meaning that the bromine will not react and the orange colour persists.
What color does bromine water change when you mix it with unsaturated fat?
There is no colour change
What happens When is bromine is added to cyclohexane?
no colour change
How does the melting point of water change as pressure increases from1atm?
Decreases
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?

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.
What is the change of state in which a solid becomes a liquid by adding heat or changing pressure?
An electric car needs a little bit of gas to run
What mining of melting point?
The melting point is the temperature at the solid and liquid states of the material are in equilibrium; if the temperature is even very slightly above the melting point, the material will melt, and if it's even very slightly below, the material will freeze. Technically the melting point depends on the pressure, but usually the dependence is not very strong; you have to change the pressure a lot (and by "a lot" I mean many multiples of normal atmospheric pressure) to change the melting point by enough to even notice.
Does there occur any change in melting point of ice by variation of pressure?
Yes, increase in pressure causes the freezing point to drop.
What pr ocesses change sedimentary rocks into metamorphic rocks?
heat and pressure, but without melting.
Two factors that are responsible for a phase change?
Change in pressure and change in temperature.
What is a change of state-science?
Changes in state can occur when a substance is heated, cooled or even if an external pressure change occurs.
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.
What is compressibility briefly?
Compressibility is the physical process of the volume change under the action of an external pressure.
