expanding and contracting

[monkey boy]

hi we all no that wood expandes in heat and contracts on the cold. is this due to the moisture within the wood:confused1:

[RobRainford]

i would assume so, branches can also fail due to dreeze/thaw, for example if there is a pocket of water in a union and we get a cold night it can 'push' the branch off. Thats what ive been told anyway! happens the same way to rocks

Strange, I thought it was the other way round

I was looking forward to seeing the secret to success! definietly looks like every one else was too!

nearly Everything expands in the heat and contracts in the cold (water being the obvious exception). That is why there is a metal strip and a gap each end of concrete road bridges for example.

No I'm pretty sure water expands too.

 

But upon freezing the molecular structure of water changes causing the expansion.
