Question
Why does lowering the temperature of an object increase its density?ABecause the mass decreasesBBecause the mass increasesCBecause the particles move closer togetherDBecause the particles spread farther apart
Solution
The correct answer is C: Because the particles move closer together.
When the temperature of an object is lowered, the kinetic energy of its particles decreases. This means they move less and therefore take up less space. As a result, the same amount of mass is concentrated in a smaller volume, which increases the density of the object.
