Which statement is true when you compare a large marble and a table tennis ball that are the same size?
A both are solids, but the marble has more volume than the tennis ball
B the table tennis ball will float in air when hit with a paddle, but the marble will not
C because it has greater density than water, the marble sinks, but the table tennis ball's lesser density means it will float
D the table tennis ball is really a gas, since it is made up of mostly air, and the marble is solid
C because it has greater density than water, the marble sinks, but the table tennis ball's lesser density means it will float
