Question
When objects contract upon cooling 2 marksvolume increases and density increases volume decreases and density decreases. volume decreases and density increases. volume increases and density decreases.
Solution
When objects cool down, they contract. This means their volume decreases. However, because the amount of matter in the object remains the same, the density of the object increases. So, the correct answer is: volume decreases and density increases.
