Surface tension can change depending on several factors! The
temperature of the liquid is super important. π₯΅
When water gets hot, the molecules move faster and stick together less, making the surface tension lower. Different liquids also have different abilities to stick together. For example, mercury has a very high surface tension because its molecules stick tightly together, which is why it forms shiny droplets! π§
Add soap to water, and it breaks the surface tension, allowing things to sink. So, temperature, type of liquid, and additives can all play a role!
