I was carrrying a pizza home and suddenly thought is the smell the wind is blowing from my pizza energy? If so surely the energy transfer must cause the pizza to loose some of its flavour?

No, it's blowing away little tiny particles of pizza away... so not loosing flavour but loosing mass...

Thanks, so effectively the wind makes my pizza weigh less? Can I complain to trading standards then :p:

Nope :p:

But yeah that's what smell is... I think it's little particles of whatever you're smelling going up your nose...

So when you smell a fart... mmmm :p:

Dogs are able to tell what you've eaten by the smell of your fart.

So am I.

It's fairly basic stuff.

A group of friends out in the pub. Sat there talking and when the drinks are finished Liam turns to paddy and says "your round"
Paddy looks back and angrily says, "so are you you fat *******."

Smell isnt energy. Your pizza will be losing heat energy, and therefore the molecules within the pizza will have a decreased average kinetic energy. The substances in the pizza will still remain and will have the same energy content.

How do you get a dog to tell you what you've eaten by the smell of your fart? They can't talk, only woof :confused:

Experiments based on certain tests where a dog is known to react in a certain way to certain smells.
