Water can decrease the viscosity of lava by disrupting the molecular structure of the magma, causing it to flow more easily. This can lead to more explosive and potentially dangerous volcanic eruptions. Conversely, in some cases water can increase the viscosity of lava, resulting in a slower flow.
Viscosity means how runny it is. Thus a lava with low viscosity will erupt fast and form long, wide spreading lava flows (eg Hawaii) and lavas of high viscosity will erupt slowly and form lava domes (eg Mt. St. Helens).
Yes, the crystal content of lava can affect its viscosity. Higher crystal content can increase the viscosity of the lava, making it more resistant to flow. This is because crystals can act as obstacles to the movement of the molten material, increasing the overall resistance to deformation.
Lava with high viscosity is called slica-rich lava
No. Viscosity is a liquid's resistance to flow. So higher viscosity means a slower flow.
The amount of water present in magma can affect the viscosity and explosiveness of the resulting lava. Higher water content can lead to more violent eruptions due to steam explosions when the water vaporizes rapidly upon reaching the surface. Lower water content typically results in less explosive eruptions with more fluid lava flows.

If the lava has cooled fast, the Cristal's will be smaller. If the lava cooled slowly, the crystals will be big

The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).
Its viscosity affects the speed of its flow. If it had a low viscosity, then its flow would be much faster and hence more menacing to the environment.
Silica content is directly proportional to viscosity, so the higher the silica content of a lava, the higher its viscosity. high viscosity means a lava will be thick and slow moving, hence probably meaning an explosive eruption. lava's with a high viscosity include rhyolite and andesite whereas lava's with a low viscosity (runny ones) include basalt.

Yes, because the hotter lava gets, the easier it can flow. The reduced density of hot lava, plus reduced hardening of the leading edge, means that it will travel much more rapidly than cooler, thicker lava.
