A tensiometer is an instrument used to measure the surface tension (γ) of liquids or surfaces in the domain of physics. Surface tension is the contractive quality of the surface of a liquid that ...

The paper clip is on the water but is not floating like a boat which is less dense than water. The paper clip is more dense than water but can rest on the surface of the water because of the water's ...

Introduction Have you ever noticed on a rainy day how water forms droplets on a window? Why does it do that instead of spreading out evenly over the whole surface? You might not guess it but this ...

Learn about surface tension with Ms. Cerrato from Asheville, NC. Learn about surface tension with Ms. Cerrato from Asheville, NC. Rootle and PBS North Carolina are proud to bring you Teacher Time, a ...

(CBS News) Let's go ahead and keep our focus on media that provide sustenance for the mind (with a dash of whimsy and fun!) rolling today. You've done a lecture on linguistics. You've done a hybrid ...

Figure 1: Physical number concentration–size distributions, total mass–size distributions and sulphate and organic-matter mass–size distributions during the NUM event. Figure 2: CCN, chemical ...

Surfactants play a pivotal role in modifying the interfacial properties between polymers and liquids. By adsorbing at both the liquid–air and polymer–liquid interfaces, these molecules can reduce the ...

Bonding over the science of Surface Tension! Why do some things float in water while others sink? The Crew’s depth of knowledge goes WAY below the surface, as they learn all about the molecular bonds ...
