When the lava hardens, it becomes a rock. Igneous (definition: formed by solidification from a molten state) rocks are hardened lava/magma. Therefore, when lava hardens, it is an igneous rock.
The material that erupts from a volcano is called lava. It consists of molten rock that flows out during an eruption.

Most of the lava is liquid. Has very LOW viscosity
Probably 1000oc till 1200oc
Materials produced when a volcano erupts are called volcanic products or volcanic materials. These can include lava flows, ash, gases, and volcanic rocks such as pumice and obsidian.
If you mean 'how does lava release itself from the volcano', it erupts through the volcano's crater. But if you mean 'how does lava erupt from the volcano', then sorry, I have no answers to that.

If in a volcano, it erupts. However, if it is just in normal lava it's going to make it explosive and very harmful
The typical cone shape of a volcano happens when sticky lava erupts upward. Sticky lava creates a dome shape and the lava cools slowly.
This is known as lava.
