Density and Buoyancy Flashcards
1
Q
Density
A
the mass of matter per unit volume; density is typically expressed in units of grams per milliliter (g/mL), grams per cubic centimeter (g/cm^3), or kilograms per cubic meter (kg/m^3)
2
Q
Weight
A
the downward force of gravity acting on mass
3
Q
Buoyancy
A
the measure of the
upward force a fluid exerts on an
object that is submerged.
4
Q
Archimedes’ Principle
A
states that the buoyant force is equal to
the weight of the fluid displaced by
an object.
5
Q
Meniscus
A
A meniscus is a curve in the surface of a liquid. A concave meniscus occurs when the liquid’s particles are more strongly attached to the container than than each other. A convex meniscus occurs when the liquid’s particles are more strongly attached to each other than the container
6
Q
Average Density
A
The total mass divided by the total volume
7
Q
Physical Change
A
A (usually) reversible change in the form or appearance of substance, but not its properties or composition.
