When a jug boils there are large bubbles in the water What are the bubbles made of?
When water boils the gasses which where absorbed are liberated and they expand as a result of the heat causing bubbles which then rise to the surface upon further heating it would be the water turning to steam that expands into bubbles, that is why the bubbles only form at the point of contact with the heat source. there could be some oxygen in the bubbles but it would be extremely small amounts as the heat does not split the bond between the oxygen and the hydrogen.

Why should a scuba diver not take a hot shower after a dive?
After a dive, nitrogen bubbles that have accumulated from a dive are small and will pass from the body in 12 hours. However...........taking a shower can make the bubbles get larger. Heat expands things. So the bubbles that become heated can get bigger and cause the bends. Never take a warm/hot shower after a dive. Especially after a deep dive.

What is the value of a Vermont quarter with a gold coloring or tint to it?
A Vermont quarter with a gold tint is not usually worth more than a regular quarter. The gold tint is caused by chemicals in the air which cause the coin to tarnish faster. It may also be from the coin being near heat for a prolonged period of time as long the heat is not too intense. The gold tint was probably caused by an increased amount of sulfur in the air. The quarter however can be valued more if the tint was caused naturally over time, since your coin is more modern, I would say this is unlikely. It is still a neat piece to own though.
