C)They are not related. |
2. What is the relationship between viscosity and temperature?
A)They are directly related. | |
B)They are inversely related. | |
C)They are not related. |
3. Why do substances with high surface tension also tend to have high viscosities?
A) Surface tension and viscosity are both directly related to the strength of intermolecular attractive forces. Liquids with high surface tension have intermolecular attractive forces sufficient to produce a high viscosity as well. | |
B) Surface tension and viscosity are both directly related to the size of the particles. The smaller the particles, the more of them are on the surface, the more bonds are incompleted, the higher the surface tension, the less molecules move in the volume, the higher viscosity. | |
C) Surface tension and viscosity are both directly related to the molar mass of the substance. The larger the molar mass, the more bonds are incompleted on the surfaces, the higher the surface tension and the slower they move, the higher viscosity. | |
D) Surface tension and viscosity are both directly related to the strength of intramolecular forces. Liquids with high surface tension have intermolecular forces sufficient to produce a high viscosity as well. |
