chapter 5 ML&M Flashcards
when a loaf of bread is compressed, its
density increases
when a chocolate bar is cut in half, its density of each half is
unchanged
if the volume of an object doubles with no change in mass, its density would be
half
Which will remain the same for two identical books, one lying flat and the other standing on an end?
weight only
blood pressure is normally greater in your
feet
water pressure is greatest against the
bottom of a submerged object
a dam is thicker at the bottom than at the top because
water pressure is greater at deeper levels
the buoyant force that acts on a submerged object is equal to
the weight of the water it displaces
ice cubes submerged at the bottom of a liquid mixture indicate that the mixture
is less dense than ice
a marshmallow in a vacuum becomes
larger
when a gas in a container expands to twice its volume, with no change in temperature, its density
is half
when a gas in a container is squeezed to half its volume at constant temperature, its density
doubles
atmospheric pressure is caused by the
the weight of the atmosphere
air in a room has
weight, energy, and mass
Pascal’s principle applies to
liquids and gases
