Substance b is found to be more viscous than substance a. this means that   1. b flows faster at room temperature than a does2. b flows slower at room temperature than a does 3. b has more mass per volume than a does4. b has less mass per volume than a does

Option (2) is the correct answer.

Explanation:

Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.

For example, honey has high viscosity.

Whereas a substance which has less viscosity is will be able to flow easily from one place to another.

For example, water has low viscosity.

So, when substance B is more viscous then it means it has high viscosity than substance A. Hence, substance B will flow slowly as compared to substance A.

Thus, we can conclude that substance B is found to be more viscous than substance A. This means that B flows slower at room temperature than A does.
