Question:
Does water temperature effect a bubble's surface tension?


Replies:
The surface tension of any liquid decreases with increasing temperature. However, this is a small effect compared to other factors such as the chemical structure of the soap used to make the bubble solution and the concentration of the soap.

Julio,

Water temperature does affect surface tension. The higher the temperature, the lower the surface tension. Basically, if the water gets warmer, it is harder for its water molecules to stick together. Soap also greatly affects surface tension. The more soap, the less tension. So, if you add the two things together, since bubbles are often made using soap, the higher the temperature of the water/soap mix, the less surface tension there would be, making it harder to make bubbles!
