Yes, depending on what material it's made of, it would have a different coefficient of thermal expansion. Materials expand with heat.
No, the amount of a liquid is volume. Density is independent of volume.
It does not because change only occurs when temperature is involved.
The volume is 50 %.
Any cubed unit depending on how big the rock is

The crank angle would change the stroke. The stroke would change the volume.
volume: obviously unaffected mass: could change, depending on what the hardening method was density: would only change if the mass did hardness: obviously copied
A [multiplicative] change in one dimension makes the same change in the volume. So the volume would be tripled.
Your question isn't specific enough. Depending on the type of metal the mass will be different and the volume will change. Heavier metals will have less volume for those 10 grams, while a lighter metal would require more volume to achieve the same 10 grams.
The answer depends on whether the change in volume was for a gas or a solid!
It is the easiest way to affect the volume which would change the density. However, if you increase the pressure but keep temperature constant the volume will also change. Any change in volume affects density.
Assuming the tank was not in a vacuum, the VOLUME stays constant. The volume is the total area inside the tank. The pressure would change when 'pumped up'. The volume would not. The pressure inside would also change based on the temperature, relative to the outside pressure.
Assuming that you could get the mass there and intact, the mass of the body would not change. Its weight, however would be zero. Depending on the matter used, the volume might be considerably reduced due to pressure.
gas has no specific volume because the molecules can be compressed or expanded, which would change the volume. like there is a smaller volume of gas in a can of soda then in the atmesphere around you.
it would change the pressure exerted by the gas in the container.
