What is the effect of increasing temperature on the density of liquids?
Correct Answer: Density decreases with increasing temperature.
- Step 1: Understand what density is. Density is how much mass is in a certain volume of a liquid.
- Step 2: Know that temperature is a measure of how hot or cold something is.
- Step 3: Realize that when you heat a liquid, the particles in the liquid move faster and spread apart.
- Step 4: When the particles spread apart, the same amount of mass takes up a larger volume.
- Step 5: Since density is mass divided by volume, if the volume increases and the mass stays the same, the density decreases.
- Step 6: Therefore, as the temperature of a liquid increases, its density generally decreases.
