Magma is never cool as it is inside the volcano with a whole load of other magna and when hardend i believe it is called something else.
Although, i presume you mean lava which is magma when it is outside of the volcano so in answer to that, the hotter it is, the runnier it is, the faster it moves.
Magma that is low in silica and produces nonexplosive eruptions is called basaltic magma. As basaltic magma has a low viscosity due to its low silica content, it tends to flow more easily, resulting in nonexplosive eruptions with lava flows.
Granitic magmas are thicker than basaltic magmas because they have higher silica content, which increases viscosity. The higher silica content leads to stronger bonding between the silica tetrahedra, making it more difficult for the magma to flow. Basaltic magmas, on the other hand, have lower silica content and are less viscous, allowing them to flow more easily.
A lava butte is generally basaltic lava. Granitic lava flows (called rhyolitic when they form at the surface) are rare and do not cover much ground.
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.
Surtsey has basaltic magma, which is associated with the eruption of shield volcanoes. This type of magma is characterized by its low silica content and fluidity, allowing it to flow easily to the surface and form lava flows.

Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.
Basaltic lava flows much faster than ryholitic lava.

The type of volcano and eruption from basaltic magma would be a cinder cone volcano. The eruption would be a mild explosive eruption. It would be mainly ash and scoria.
Viscous and silica-rich magma, such as dacite or rhyolite, often erupts out of dome complexes. Due to its high viscosity, this type of magma tends to form domes and does not flow as easily as basaltic magma.
No, granite does not form as a lava flow. Granite forms deep underground from the slow cooling of magma. Lava flows are composed of different types of igneous rocks, such as basalt or andesite, that form at the Earth's surface during volcanic eruptions.
It affects the rate of flow of the lava. Hotter means faster flow
