FLUID DYNAMICS EXAM SCRIPT FINAL
PAPER 2026 SOLVED QUESTION SET
GRADED A+
◉What are the main points of the particle theory of matter?
Answer: 1. All matter is made of tiny particles. 2. Particles have
empty spaces between them. 3. Particles are moving randomly all
the time. 4. Particles move faster and spread farther apart when
heated. 5. Particles attract each other.
◉How do gases differ from liquids in terms of shape and volume?
Answer: Gases do not have a definite shape or volume, while liquids
have a definite volume but take the shape of their container.
◉What is a key characteristic of fluids? Answer: Fluids have the
ability to flow.
◉How do particles behave in a solid? Answer: Particles are tightly
packed and locked in place, vibrating around a central point.
◉What allows liquids to flow? Answer: The particles of liquids are
farther apart than in solids and can move past one another.
, ◉How do gas particles compare to liquid particles? Answer: Gas
particles are much farther apart and have extremely weak forces of
attraction compared to liquid particles.
◉What is Goobleck and how is it used in experiments? Answer:
Goobleck is a mixture of cornstarch and water used to investigate its
properties as a liquid or solid.
◉What is laminar flow? Answer: Laminar flow is smooth and
regular fluid movement in orderly lines.
◉What is turbulent flow? Answer: Turbulent flow is choppy and
irregular fluid movement, often seen in rivers.
◉How does laminar flow benefit vehicles moving through fluids?
Answer: It reduces resistance or drag, making the vehicle more
efficient.
◉What effect does turbulent flow have on rivers? Answer: It adds
oxygen to the water, which is essential for aquatic life.
◉What happens to solids when ground into fine fragments?
Answer: Some solids can appear to flow, like salt, but they still retain
a definite shape.
