What allows rock melting to begin at convertgent plate boundaries?
Water reducing the melting point.
What does a solid turn into when its heated?
When a solid gains thermal energy, its atoms and/or molecules begin to move (vibrate) faster and faster as the temperature continues to increase. Eventually, the particles that make up the solid will gain enough thermal energy in order to separate into a liquid through melting or into a gas through sublimation.
How can ice can be changed to water?
By melting it. The melting point of ice is 0 °C (32 °F, 273 K). When it reaches this temperature, it will begin the process of becoming water.
Does the complete solid gets converted into liquid at its melting point?
Not necessarily, the melting point is usually just the point at which the solid will begin to transform into a liquid. There is usually a melting point range for most solids, meaning the temperature range the solid will completely melt. However, if the solid is extremely pure the range will be very small (only 1-2 degrees Celcius) therefore different books report different melting points for various solids. The Merck Index is a really reliable source for anything to do with any substance, be it physical properties such as melting point, to chemical properties such as reactivity.
How did gases create the Sun?
Gravity! Get ENOUGH gas, as light and tenuous as it is, and its own self-gravity will cause the gas to collapse in the center. if there's enough mass, it will get more and more dense, and eventually get hot enough to begin nuclear fusion.
What portion of the mantle is hot enough to begin melting rocks into magma?
asthenosphere
Where can one find information about mantel clock?
Mantel Clocks have been around since the 18th Century and were made in countries like, America, France and Germany. Should anyone like to begin collecting or just finding out more information about mantel clocks, doing research would be good. Type in something like 'the history of Mantel Clocks', and you should be able to do some really good research about Mantel Clocks.
What allows rock melting to begin at convertgent plate boundaries?
Water reducing the melting point.
What spring words begin with letter I?
Ice melting is a spring word. It begins with the letter i.
How does replacation begin in DNA?
DNA melting and unwinding at the origin of replication.
How hot can ice-cream get with out melting?
Ice cream cannot get "hot" at all before melting. It will begin to melt as soon as it is removed from refrigeration.
At which temperature does a solid changes to a liquid?
Substances have different melting points. When a substance reaches it melting point it will begin a phase change. Wikipedia's chart for elements of melting points. http://en.wikipedia.org/wiki/List_of_elements_by_melting_point
When snow and ice begin changing state from solid to liquid the physical change is called?
Melting
What happens when ice is placed in a warm glass of water?
The ice will begin melting and will cool the warm water.
Describe the movement of the particles at the melting point of a substance?
At its melting points the particles of a substance become looser and can move more freely. There is no order unlike a solids particles, however there isn't complete freedom to move everywhere unlike gases particles.
Why would a plume of solid silicate rock rising slowly from deep in the mantle begin melting as it neared the base of the lithosphere?
Temperatures remain high as lowered pressures decrease melting temperatures.
What happens to the particles as the temperature of a solid increases?
Nothing until it hits its melting point. Once it hits its melting point, its particles begin to move more freely, and the solid turns into a liquid.
