Test#1: term 2: Compress. and Incompress. Fluids, sec 3

Question 1

Why is liquid an incompressible fluid ?

Answer 1

• spaces between particles in a liquid are almost non-existent.
• when force is applied to liquid, particles can’t move closer to one another –> pressure doesn’t change.
• force is transmitted from one particle to the next, makes liquid squirt out.
• liquid=incompressible because their volume cannot be reduced.

Question 2

Why is gas compressible ?

Answer 2

• spaces between gas particles are large = gives property of being compressible.
• Gas has capacity to diminish in volume when force is applied.
