yes because deep down in the sea it is about 2 decrease Celsius in normal air is about 27 decrease Celsius and the lava is around 100 decrease Celsius. so yes lava would cool down faster in the sea.
No. While the day side of Mercury is quite hot, it is not nearly as hot as lava. So any lava that would erupt on Mercury would still cool down and solidify. The lack of an atmosphere would mean that the lava would cool more slowly than lava on Earth does.
The solidified lava forming the walls of the lava tube will act to insulate the molten lava. It will therefore cool more slowly than lava at the surface and so will have a lower viscosity (it will be more runny) and so will flow faster than lava at the surface.
No. Lava heats up the air. In turn, the air cools the lava.
It can cool lava somewhat, but so does air or anything else that is at a lower temperature than the lava. It would not cool lava enough to make noticeable difference.
Lava takes a long time to cool down because it has very high temperatures, sometimes exceeding 1,000 degrees Celsius. The large difference in temperature between the lava and its surroundings means heat transfer happens slowly. Additionally, lava is a poor conductor of heat, further contributing to the slow cooling process.
Lava cools down primarily through heat loss to its surroundings, such as the surrounding air and ground. Water can also cool lava quickly by causing it to solidify rapidly. Other methods include covering the lava with ash or other insulating materials to help it cool more slowly.
Air at Earth's surface is much cooler than lava is, the lava will start to transfer heat to the air on contact. The air heats up and the lava cools down.
Yes, it does, I don't know how exactly how, but it does
This is a silly question...No! Magma (not lava) can melt (not burn) and include some material sorrounding it but could never melt an entire volcano as it would cool down and become solid in doing so.
it needs to cool down
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
