“How can surfaces with friction help with flood resilience?”

 

Floods can devastate nearby communities with their fast-approaching behavior. However, if the land nearby has frictional elements such as foliage, then the flood energy can be dissipated and prevent destruction. Mangrove forests are a common example of this process. This is How Surfaces With Friction Can Help With Flood Resilience.

“Why is bronze stronger than stone?”

 

The transition from stone to bronze marked humanity’s transition from the caves to civilization. This was brought by the ability to use this stronger material allowed for the creation of more complex machinery and structure. But what makes bronze stronger than stone? Well, it all comes down to the fact that it has a more compact molecular structure, giving it more strength! This is Why Bronze Is Harder Than Stone.

“How can we measure how porous an object is?”

If an object is porous it means that it has empty space in it. The measure of this empty space is known as the Porosity, and can be found on a sliding scale from zero percent to one hundred percent.

“Why does physics dictate that overheated solar panels will have lower efficiencies?”

The amount of solar energy that can be created by a solar panel is dependent on the difference in voltage between the electrons at the rest state and the activated state. However, as a solar panel becomes hotter, the rest state will be pushed outwards while the active state will be held constant. This results in a decrease in voltage and by extension power output. This is The Physical Reason for Why Overheating Lowers Solar Panel Efficiency.

“How is radiative forcing causing climate change?”

Radiative forcing is the primary driver of Earth’s climate. And since the Earth is trapping more heat, its radiative forcing is increasing and making temperatures hotter. This is  How Radiative Forcing is Causing Climate Change.

“What happens when water has a super-high concentration of salt?”

It is hard for humans to digest water with salt mixed in. So when water has an ultra-high concentration of salt, it takes on interesting properties. The salinity of this Brine can be used for food-processing, de-icing roads and structures, and as a refrigeration fluid. Brine is one of the myriads of chemicals that allows our modern world to work.
