The density of an object is a) The mass divided by the volume D = m/v b) The volume divided by the mass D = v/m c) The same as its weight d) The same as the size of the object
Option b
If two objects have the same volume but one has a greater mass, the one with greater mass a) Has a lower density b) Has a higher density c) Will float d) Will sink
Option a
If you cut a wooden block in half, each half would have a) Half the density of the original piece b) Twice the density of the original piece c) The same density as the original piece d) No density at all
option c
If two objects have the same mass but different volumes a) The one with the larger volume has the lower density b) They must have the same density c) The one with the larger volume has the higher density d) The one with the larger volume is
option a
If the density of water is 1 gram/cm3 , this means that the mass of 100 cm3 of water should be a) 100 grams b) 50 grams c) 1000 grams d) 1 gram
option a
. An object should float in a liquid if it is a) More dense than the liquid b) Less dense than the liquid c) Lighter than metal d) Shaped like a ball
option b
A tiny piece of sand is very light but sinks in water. This is because a) Sand is a solid b) Sand is less dense than water c) There is more water than sand d) Sand is more dense than water
option d
. A carrot floats in salt water but sinks in fresh water. This is because a) Salt water is more dense than fresh water b) Fresh water is more dense than salt water c) The carrot is more dense than salt water d) A larger piece of carrot has
option a
