Our theories of physics indicate that the speed of light should be invariant (unchanging) anywhere in the universe.
Mass.
It is normally believed that the Universe's total mass remains constant.
Yes. Ride an elevator and your weight changes, but your mass remains constant.
Yes, it will increase so that density of the material always remains constant.
The most dense material in the universe is stellar ash - the remains of a star that has come to the end of it's life. A teaspoonful of stellar ash would weigh on earth thousands - to millions - of tons.

no it does not remain contant.
Mass
In general ultrasonic velocity is considered as a constant value relative to the material.
In a vacuum, light travels at a constant speed of about 186,282 miles per second (299,792 kilometers per second). This speed is the fastest possible speed in the universe and remains constant.
Yes. Ride an elevator and your weight changes, but your mass remains constant.
The entropy does not remains constant if the system is not isolated.
Yes, it will increase so that density of the material always remains constant.
because values of charge and mass of electron remains constant whatever may be the material.
