Q. When boiling pasta, how many phases of matter does water go through?
3
1
2
The number depends on the number of water molecules.
None of the above
Q. What list does not represent a list of fluids?
Shampoo, conditioner, water, soap
Ozone, Argon, carbon monoxide, Helium
Planets, stars, moons, galaxies
Pressure, density, volume, force
Neutrons, protons, electrons, atoms
Q. An apple is at rest on a table. What forces are at play?
Friction and pressure
Weight and friction
Normal force and weight
Normal force and gravity
c or d
Q. Two Fuji apples have different surface areas but identical masses. Which apple is denser?
The apple with a smaller surface area
The apple with a larger surface area
The apple with the largest volume
Both apples have identical densities.
The apple with the larger mass
Q. What atmospheric pressure does a 1 kg cube feel in your house if it has a surface area of 600 m2?
0.0016 Pa
0.0033 Pa
1.013 × 105 Pa
There is not enough information to solve this problem.
Q. Two men go diving together in the Caribbean. The first man weighs 180 pounds. The second one weighs 170 pounds. What pressure do they feel when they reach a depth of 10 m?
2.02 × 105 Pa each
1.010 × 105 Pa each
The heavier man will feel more pressure, but there is not enough information to compute an exact amount.
1.013 × 105 Pa each
The lighter man will feel more pressure, but there is not enough information to compute an exact amount.
Q. An object has a density of 
. What happens when you drop the object in a deep lake?
. What happens when you drop the object in a deep lake? The object floats.
The object sinks to the bottom of the lake.
The object sinks but reaches a state of hydrostatic equilibrium before hitting the bottom.
It depends on the object's speed once it hits the water.
There is not enough information to answer this question.
Q. King Hiero's 1.2-ton car breaks down again so he brings it back to Mechanic Crook, the one who charges $10 per Newton to lift a car. He offers a choice of two hydraulic lifts: the first one has a ratio of 
and the second lift has a ratio of 
. Which lift should he choose?
and the second lift has a ratio of . Which lift should he choose? Both lifts will cost him the same amount of money.
Neither lift would be strong to lift up a car.
The second lift
The first lift
a and b
Q. An ideal fluid has:
A high viscosity and zero compressibility
A low viscosity and zero compressibility
A high friction and low compressibility
Zero viscosity and zero compressibility
Zero viscosity and zero movement
Q. A pipeline has two different areas A1 and A2, where A1 is larger than A2. What can be said about the motion of fluid through this pipeline?
The flow volume is constant.
The velocity is constant.
The pressure is constant.
The movement of the fluid is acted upon by contact forces.
The number of flow lines will change once it passes through the second area.
