Code Red -Climate Warning

I like to do my bit for climate change.

Instead of filling the basin for a shave, I like to leave the hot tap running for the duration of the task - gives the razor a better clean. Recently started using hot water for teeth brushing, again running the tap for duration. 
 

With foreign holidays becoming more expensive and less frequent we should all do our bit to make ‘holidaying at home’ more appealing.

I leave my fridge door open to help cool down the planet. 

Good source of light too which should help with the leccy bill ?

? Water isn't wet?  Incredible thing to say. 

Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.

Whether an object is wet or dry depends on a balance between cohesive and adhesive forces. Cohesive forces are attractive forces within the liquid that cause the molecules in the liquid to prefer to stick together. Cohesive forces are also responsible for surface tension. If the cohesive forces are very strong, then the liquid molecules really like to stay close together and they won't spread out on the surface of an object very much. On the contrary, adhesive forces are the attractive forces between the liquid and the surface of the material. If the adhesive forces are strong, then the liquid will try and spread out onto the surface as much as possible. So how wet a surface is depends on the balance between these two forces. If the adhesive forces (liquid-solid) are bigger than the cohesive forces (liquid-liquid), we say the material becomes wet, and the liquid tends to spread out to maximize contact with the surface. On the other hand, if the adhesive forces (liquid-solid) are smaller than the cohesive forces (liquid-liquid), we say the material is dry, and the liquid tends to bead-up into a spherical drop and tries to minimize the contact with the surface.

 

Summary:

 

Wetness isn't a property of a liquid, it is a property of an interface. Thus, water alone cannot be wet. However water has a propensity to wet things. It generally has liquid-liquid interactions that are weaker than a lot of solid-liquid interactions which allow it to wet a lot of surfaces. However, there are several surfaces that won't be wetted by water.

Here's a website which is either the one Boof copied this from or it's very similar. ?

FFS. That's a mega whoosh. 

No it’s not. The joke was that people were using energy to do things inefficiently or pointlessly. 
 

A solar panel can’t consume energy unless it has been modified. Hans uses energy to make the blades to turn. Your solar panel can’t shoot solar rays back into the atmosphere, therefore it has no means of consuming energy.

 

Its ok you’re a retard we get it.
