I'm stuck on this lab report question. i have a list of questions i have to answer on how does temperature change affect surface tension? but then they asked what's the purpose of this can someone with

The temperature influences in the movement of molecules, the energy they contain.

When there is more energy (hotter) molecules move more therefore there is less surface tension.

When there is less energy (colder) molecules moce less therefore there is more surface tension.

To find the answer to "What is the purpose of this investigation?" you'll have to go through the context and through what you've studied so far. But the answer should be something like this: "To test the effects of temperature variation and surface tension".

Hope it helped,

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
