How Would You Describe The Viscosity And Velocity Of Lava?

The viscosity and velocity of lava is based off of the temperature, silica content, and gas content, and water content of the lava. Velocity and viscosity are used to describe the speed of lava, because the viscosity is the thickness of the lava, while the velocity is the speed, which is based on the viscosity because the greater the viscosity the lower the velocity. In C period cold B, the cold ‘lava’ flowed slower than that of a group with hot ‘lava’. This is because the colder the ‘lava’ the greater the viscosity, because the molecules are closer together than that of the hotter ‘lava’. In the group, C period cold B, the data showed an average velocity of 0.97cm/sec. This information is not 100 percent accurate however, because the amount of time the ‘lava’ was off of the ice before it was poured on the pancake, and the amount of ‘lava’ poured was not the same every trial, which resulted in a wider range of data.

After taking out the outliers, the average for team cold was 0.91cm/sec. The team room average which was 4.83cm/sec was greater than the average velocity for team cold because unlike the ‘lava’ for team cold, the ‘lava’ was kept at room temperature, so the viscosity was lower. For team hot, the ‘lava’ was kept in a crock pot, so the temperature of the ‘lava’ was greater than that of teams cold and room, and therefore, had an even lower viscosity. This also resulted in the ‘lava’ having a greater velocity. After taking out the outliers for team hot, the average velocity was 7.15cm/sec. Although temperature has a large impact on the viscosity of lava, the gas, water, and silica contents also play a factor on the velocity of lava, and therefore, the explosion of the
