A)The car's weight and volume change, but not its mass.
B)The volume of the car changes as well as its average density.
C)The car's temperature changes, but not its average density.
D)The mass of the car changes as well as its volume.

Quizplus · Accepted Answer

When a junked car is neatly crushed into a compact cube, its volume changes (it becomes much smaller) and its average density changes (it becomes much larger due to the same mass being compressed into a smaller volume). The mass of the car remains unchanged during this process. Temperature is not a relevant physical quantity in this case. Therefore, option B is the correct answer.
