Not only the pressure but especially the friction between the steel of skates and ice release heat.

Does melting point depend on atmospheric pressure?

Yes, the melting point of a substance can be influenced by atmospheric pressure. In general, an increase in pressure raises the melting point of a substance, while a decrease in pressure lowers it. This is because pressure affects the equilibrium between the solid and liquid phases.


What processes is most affected by pressure freezing or boiling or melting?

Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.


Why does high pressure under skaters shoes lowers melting point of ice?

Because it does. That's what the phase diagram for water looks like. By the way, this is kind of a discredited notion. The freezing point is technically dependent on pressure, but it's a very small effect and isn't really going to matter much unless the temperature is very near the normal freezing point anyway.


Does the presence of water raise the melting point of felsic magma?

No. Water lowers the melting point of magma, both mafic and felsic.


Is melting of the mantle achieved by decreasing pressure at divergent plate boundaries?

Melting of the mantle at divergent plate boundaries is primarily caused by the decrease in pressure as the tectonic plates move apart. This reduction in pressure lowers the melting point of the mantle rock, allowing it to melt and form magma that can rise to the surface and create new crust. Magmatic activity at divergent boundaries is a key driver of seafloor spreading and plate tectonics.

How does the presence of water affect the melting temperature of rock?

The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.


What are the effects of pressure on melting boiling points of a substance?

Increasing pressure generally increases the melting and boiling points of a substance. This is because pressure forces molecules to be packed closer together, making it harder for them to break free from each other in the solid or liquid phase. Conversely, decreasing pressure lowers the melting and boiling points.

What do you think salt does to the melting point of ice?

Salt lowers the melting point of ice.


How does water affect the melting temperature of rock?

In theory yes: increasing pressure will increase the melting point mostly (not for ice!). In practice: it is hardly noticable, not significant at all, for most solid materials.Pressure increases the melting point of rock. The molecules are packed tighter together and thus take more energy to liquefy.


Why does melting occur at divergent plate boundaries?

Hot mantle rock rises where the plates are moving apart. This releases pressure on the mantle, which lowers its melting temperature. Lava erupts through long cracks in the ground, or fissures


What lowers the melting point in alumina?

What factors affect the melting and freezing points of water?

The melting and freezing points of water are primarily affected by external pressure and the presence of impurities. Increasing pressure raises both points, while adding impurities lowers them. Additionally, the purity of the water molecules and the surrounding environment's temperature also play a role.
