Question

Substance B is found to be more viscous than substance A. This means that _____.

1. B flows faster at room temperature than A does
2. B flows slower at room temperature than A does
3. B has more mass per volume than A does
4. B has less mass per volume than A does

Answer 1

Answer: Option (2) is the correct answer.

Step-by-step 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.
