No. Higher silica magmas tend to be more viscous.
The viscosity of a dilute dispersion of silica particles in water would depend on factors such as the particle size, concentration, and surface chemistry of the silica particles. In general, the addition of solid particles to a liquid can increase viscosity due to the particles disrupting the flow of the liquid. The viscosity can be measured experimentally using viscometers.
An increase in the silica content of a lava increases it's viscosity. Viscosity can be thought of as a fluids resistance during deformation to shear or tensile stress, or in more simple terms, how easy or difficult it is to make a fluid flow. As viscosity increases, a fluid will flow less easily, so a lava with a high silica content will be more viscous and will flow less easily / more slowly than a low silica lava.
The amount of silica and water affect the viscosity of the magma. The more viscous the magma, the slower the flow rate and the shorter and the thicker the flows. Silica makes for a more viscous magma.
The mineral that significantly affects the thickness (viscosity) of magma is silica. Higher silica content in magma leads to increased viscosity, making it thicker and more resistant to flow. Conversely, magma with lower silica content is less viscous and flows more easily. This variation in viscosity plays a crucial role in determining the type of volcanic eruptions and the shape of volcanic landforms.
If an eruption is quiet, it typically indicates that the magma has low viscosity due to high silica content. The high silica content causes the magma to be more fluid, allowing gases to escape easily and resulting in a gentle eruption with less explosive activity.
If something has a greater viscosity, it becomes more 'runny' compared to its original state when heated up. The greater the change from thick to runny = the greater the viscosity. So honey has a greater viscosity than water for example.

You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.
