Question 1.
Define conservation of mass in your own words.
Show hintHide hint
Consider closed systems like containers.
Question 2.
What is an extensive property? Give an example.
Show hintHide hint
Think about what happens to total energy if you double the mass.
3Question 3.
What does the conservation of mass state?
- A. Mass can be created.
- B. Mass remains constant.
- C. Mass can change.
- D. Mass is irrelevant.
Show hintHide hint
Think about a sealed container.
4Question 4.
True or False: Extensive properties depend on the mass of a substance.
- True
- False
Show hintHide hint
Contrast this with intensive properties.
Question 5.
A closed water tank experiences inflow and outflow through two pipes. Explain how you would apply conservation of mass to determine the change in water level over time.
Show hintHide hint
Assume constant inflow and outflow rates unless stated otherwise.
Question 6.
A fluid system has varying energy levels due to external work done. Apply the conservation of energy principle to determine how this affects the overall fluid motion.
Show hintHide hint
Consider all forms of energy introduced into or removed from the system.
