The SI unit of pressure is:

• Pascal

• Newton

• Joule

• Bar

Surface tension acts:

• Perpendicular to the liquid surface

• Parallel to the liquid surface

• Along the radius of curvature

• Against gravity

Which of the following has the lowest viscosity?

What happens to the viscosity of a gas when temperature increases?

• Increases

• Decreases

• First increases then decreases

The bulk modulus of a fluid is a measure of its:

• Viscosity
