What is the effect of increasing the temperature on the density of most liquids?

Step 1: Understand what density is. Density is how much mass is in a certain volume of a substance.
Step 2: Know that most liquids are made up of molecules that are close together.
Step 3: When you increase the temperature of a liquid, the molecules start to move faster.
Step 4: As the molecules move faster, they push away from each other, causing the liquid to expand.
Step 5: When the liquid expands, the same amount of mass takes up a larger volume.
Step 6: Since density is mass divided by volume, if the volume increases and mass stays the same, the density decreases.
