Properties of Matter
Which are older: the atoms in the body of an elderly person or those in the body of a baby?
The age of the atoms in both is the same.
This is the measure of how much mass is in a given volume.
What is density?
This is the formula used to solve for pressure.
P = F/A
This is the pressure caused by the weight of air.
What is atmospheric pressure?
This geometrical figure has the smallest surface area for a given volume.
What is the sphere?
This is the smallest particle of an element that has all of the element’s chemical properties.
What is an atom?
Does a substance's density change if you have more or less of it? (Y/N)
No. A substance's density remains the same, despite how much of it you have.
True or False? Archimedes' principle tells us that any object that displaces 10 N of liquid will be buoyed up with 10 N.
True
This is the device used to measure atmospheric pressure.
What is a barometer?
The hydraulic press demonstrates which scientific principle?
What is Pascal's principle?
In a (a. solid, b. liquid, or c. gas), atoms vibrate in place.
What is a solid?
If the density of water is 1 gram/cm3 , this means that the mass of 100 cm3 of water should be:
100 g
Archimedes’ Principle states that an object made out of steel, such as a ship, can be made to float because of its unique _______________, which displaces a large volume of water.
Archimedes’ Principle states that an object made out of steel, such as a ship, can be made to float because of its unique shape, which displaces a large volume of water.
The higher the altitude, the (higher or lower) the air pressure
The higher the altitude, the lower the air pressure
A fluid is either a ____ or a _____
A fluid is either a liquid or a gas
Common table salt is an example of a(n) (a. element, b. compound, or c. mixture)
What is a compound? (Sodium chloride: sodium and chlorine)
When something is pulled or stretched, this is called:
What is tension?
This is the name of the net upward force that a fluid exerts on an immersed object.
What is the buoyant force?
This is the reason why a bag of air feels weightless while a bag of water does not.
A bag of air feels weightless because we are immersed in air, just as a bag of water would feel weightless underwater.
A paper clip rests on water, pushing the surface down slightly without sinking. This is an example of . . .
This man first advanced the idea of atoms in the early 1800s
Who is John Dalton?
When something is pushed in or squashed, this is called:
What is compression?
A change in pressure at any point in an enclosed fluid at rest is transmitted ______ ____ _____ _____ in the fluid.
Which principle is this?
A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.
This is Pascal's principle.
Pressure is (uniform or not uniform) throughout the atmosphere.
Pressure is not uniform throughout the atmosphere.
Finish the sentence: A floating object displaces a weight of fluid ____ ____ ____ ____ ____.
Which principle is this?
Finish the sentence: A floating object displaces a weight of fluid equal to its own weight.
This is Archimedes' principle.
This man proposed that all matter is made of 4 elements (earth, air, fire, water)
Who is Aristotle?
Diamond is an example of a ______ substance.
Rubber is an example of an _______ substance.
Diamond is an example of a crystalline substance.
Rubber is an example of an amorphous substance.
These are the 3 factors that together influence the sinking and floating of objects.
What are gravity, density, and buoyancy?
Barometers use this kind of metal to perform their measurements
What is mercury?
For Pascal, all of humanity's problems stem from this one thing
Man's inability to sit quietly in a room alone
