What changes igneous or sedimentary rock into metamorphic rock?
Heat, pressure, or transfer of elements through high temperature solutions.
What has to happen for metamorphism occur?
Heat and high pressure
What are the conditions needed for a metamorphic rock to form?
they are normally formed inside or very near volcanoes. To form igneous rock magma must cool the it will turn into and igneous rock (intrusive or extrusive)
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 keeps earth inner core from melting?
Minerals are formed by elements coming together, and then lots of pressure and heat is added over millions of years.
Which type of rock forms becaues of high heat and pressure without melting?
metamorphic rock
What changes igneous or sedimentary rock into metamorphic rock?
Heat, pressure, or transfer of elements through high temperature solutions.
Why are the freezing melting and boiling points lower on high altitude?
Heat is only energy. In areas of low pressure, such as high altitudes, "heat" particles, which are charged electrons, escape more quickly. As more "heat" (electrons) escapes more quickly, things freeze more quickly. As far as I know melting and boiling points are higher, not lower in high altitudes.
What will be the melting point ice if it is kept under high pressure?
The melting point is not changed by pressure. It is still over 32O
Benefit of heat sinks in CPU?
It keeps your processor from melting. Do not run a PC without a heat sink on your processor. Processors can get to extremley high temperatures. The heat sink absorbs this heat and removes it using a fan.
What has to happen for metamorphism occur?
Heat and high pressure
Which factor is most important for each type of metamorphism?
regional: heat and pressure and shear stress (LOCAL)- contact: heat- high pressure- low deformational: high -pressure, low- heat
What does the condenser do in a refrigeration or air conditioning system?
It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.
What does heat allow melting to occur?
Because melting occur at high temperature; at this temperature bonds between particles are weaker.
What process can change metamorphic rock into sedimentary?
When the sedimentary rock is going under heat and pressure, turning it into a metamorphic rock.
What are the conditions needed for a metamorphic rock to form?
they are normally formed inside or very near volcanoes. To form igneous rock magma must cool the it will turn into and igneous rock (intrusive or extrusive)
What is high melting point?
The melting point of a solid is the temperature at which it changes STATE from SOLID to LIQUID. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends (usually slightly) on pressure and is usually specified at STANDARDatmospheric pressure.
