Question

The units of surface tension and viscosity of liquids are respectively ______.

Options

• kg m^–1 s^–1, N m^–1

• kg s^–2, kg,^–1 s^–1

• N m^–1, kg m^–1 s^–2

• kg s^–1, kg m^–2 s^–1

Answer 1

The units of surface tension and viscosity of liquids are respectively kg s^–2, kg,^–1 s^–1.

Explanation:

Surface tension unit = N m^–1 = kg s^–2

The viscosity coefficient is used to calculate viscosity.

Viscosity coefficient unit = N s m^–2 = kg m^–1 s^–1
