Chapter 3, Problem 6TE

When a junked car is crushed into a compact cube, does its mass change? Its weight? Its volume? Explain

To determine

The change in mass, weight and volume of a junked care when it’s crushed in a compact cube.

Answer to Problem 6TE

There will be no change in mass and weight but the volume will decrease when junked care is crushed in a compact cube.

Explanation of Solution

The weight is the force due to gravity, which acts in the downward direction. The weight of the object is directly proportional to the mass of the object. So, as the mass of the body increases, the weight also increases. The volume is the measure of space that a body occupies.

When a junked car is crushed into a cube, the mass does not change as the amount of matter does not change even after crushing the car.

The weight will also remain the same, as the mass is not changing, after crushing the car.

The volume will decrease when the car is crushed into a compact cube.

Conclusion:

Therefore, there will be no change in mass and weight but the volume will decrease.
