Q: What happens to the surface tension of water as temperature increases?
Solution:
The surface tension of water decreases as temperature increases.
Steps: 6
Show Steps
Step 1: Understand what surface tension is. It is the force that makes the surface of water behave like a stretched elastic sheet.
Step 2: Know that temperature is a measure of how hot or cold something is.
Step 3: Realize that when water is heated, the molecules move faster and spread apart.
Step 4: As the molecules spread apart, the attractive forces between them at the surface weaken.
Step 5: Since the attractive forces are weaker, the surface tension decreases.
Step 6: Conclude that as the temperature of water increases, its surface tension decreases.
