1. A fluid can only be a liquid.
True <<
False
2. One atmosphere is equal to 14.7 psi.
True <<
False
3. In a fluid, pressure depends on the density of the fluid and the depth.
True
False <<
4. Pascal's Principle says that the buoyant force on an object floating in a fluid is equal to the weight of the volume of fluid that the object displaces.
True <<
False
5. Archimedes' Principle says that the buoyant force on a floating object is equal to the weight of the volume of fluid that the object displaces.
True
False <<
6. The velocity of a fluid flowing through a tube is directly proportional to the area of the tube.
True <<
False
7. According to Bernoulli's equation, when a tube changes from a large diameter to a small diameter, the velocity increases and the pressure decreases.

3. I would say yes assuming g constant, p = rho g h
Of course it also depends on velocity and acceleration
4. That is ARCHIMEDES !!!!!!!
5. Pascal did lots of things, but not Archimede's Principle
6, No, no, no !!
look up "Bernoulli's principle.
7. is TRUE !!!! Bernoulli again
p + (1/2)rho v^2 is constant (if flow steady and no friction)
Q = flow rate (none disappears so
Q = v*area = V*AREA all along as long as flow constant
8. I would say sort of true although fluid friction proportional to "rate of shear" rather than shear.
