Why does running hot water sound different to running cold water?

The hot water in my house takes a moment to come through when turning on a tap or the shower.  While heating up, the noise of the water hitting the sink etc changes pitch as it changes from cold to hot.  Why is this?

Is it possiable for bacteria to live in lava?

Ive recently seen an advert by Dettol which sees to trying to scare people even more than their usual methods, claiming that some bacteria can survive in lava http://bit.ly/bAJm3e. I wouldn't have thought this possiable because of the extreme temperatures and preasures the molten rock would exibit on soft object, as well as the lack of a food source that they would need to live for any amount of time. So should I worry about getting the flu if i ever fall in lava?

Water used to soak soiled laundry with plain vanilla detergent seemed cooler to the touch than with less soiled laundry. Why?

The water came from one full pail and I had divided the water into 2 portions. Both washings were done at the same time.
