lava is extremely hot when it emerges from the Earth's interior. It cools quickly, but in proportion to the ambient temperature, and probably also its thickness and its emerging temperature.
Lava which erupts on the sea bed obviously cools much faster than those which emerge on the sunny side of a mountain! :-)
so when you are running down the volcano with the lava at your heels, remember it is is cooling and slowing every second......

Once lava is visible nothing is keeping it hot. The cooling process has begun because everything around it is at a cooler temperature. The reason it is hot when it emerges from the earth is because it came from the Earth's core where everything is "lava".

well, lava is the term used when the magma is exposed flowing above the earth's surface - then in fact it cools down very rapidly, the only thing keeping it hot is high subsurface temperatures from the magma chambers below or adjacent lava flows

The hot magma beneath the Earth's crust.
