Why the strings of lower tones are thicker or heavier?
So, the sound can be lower. It has to be like that because it has to create more vibration waves. The thicker/heavier the strings are, the more vibration waves occur, which makes the tone lower.
Why don't high mass stars rekindle after collapsing?
They do. Each time their cores run out of the current fuel, they undergo gravitational collapse, heat up and start to fuse the next element in the sequence. Each time this happens the core gets hotter and the surface of the star expands (making red giants). Eventually the element Iron (Fe) is made in the core and at this point the star dies because you can not fuse Iron into anything heavier and get energy out - all elements heavier than Iron absorb energy as they are made. Thus as soon as a ball of Iron is made in the star's core there is no energy there to fight the pull of gravity and the core shrinks to become a superdense ball of neutrons or if the star is very massive a black hole. As this happens the star explodes as a supernova.
Is a banjo smaller than a violin?
The banjo is usually larger and heavier than a violin
Are clouds made of molecules of pure oxygen?
No, clouds are made of water that is heated up so it raises. It then condenses and becomes clouds. The cloud the gets tighter and tighter filled and the water gets heavier and heavier and then it falls down as rain.
As heavier elements are formed by fusion a massive star expands into?
Stellar evolution
Does a gas become heavier than air when it condenses into a liquid?
This depends on the gas.
What happens to water as it gets denser?
If you mean when the number of water molecules increases in an area, then it becomes heavier, by volume. But if you mean when it cools down and becomes ice, then it becomes a crystalline structure and it actually expands and thereby becomes lighter than the surrounding area and floats. Sorry for two answers, I wasn't sure what exactly you meant. :)
As heavier elements are formed by fusion a massive star expands into a what?
A super giant
Why does air rise when it is hot?
When air gets hotter, or when any gas gets hotter, it expands. This means its density will decrease; therefore, cooler (and heavier) air will push it up.When air gets hotter, or when any gas gets hotter, it expands.

What does air do when it cools?
It becomes more dense and heavier.
What becomes heavier after getting burnt?
Magnesium becomes heavier after it is burnt. This is because the magnesium has chemically bonded with oxygen to form magnesium oxide. The oxygen adds the extra weight.
What happens when heavier elements are formed by fusion then a massive star expands?
yes as heavy elements are used for fuel the star expands this is what will happen to the earth it will swell to a red giant engulfing the inner 3 planets as it slowly dies
What becomes larger when it changes it jacket but does not become heavier?
