How does temperature relate to density?
A
As temperature decreases, density decreases.
B
As temperature decreases, density increases.
C
Temperature does not change density.
D
As temperature increases, density increase

Answer 1

The correct answer is **B: As temperature decreases, density increases.**

Here's the explanation:

Density is defined as mass per unit volume (density = mass/volume). When the temperature of a substance decreases, its volume generally decreases (in most cases, like solids and liquids), leading to an increase in density if mass remains constant. Conversely, when temperature increases, substances typically expand, increasing volume and decreasing density.

So, in general:
- As temperature decreases, density increases.
- As temperature increases, density decreases.
