30 grams because of conservation
No, options are given but I believe the answer would be
In a water cycle Solid state of matter has the particles closest together.
I think it would be yes because the drum is submerged in water and the water would slow the sound waves, making the sound softer. Right?
I’m going to use molasses as an example of a substance.
The mass and volume both change when changing the amount of molasses.
However, the density does not change. This is because the mass and volume increase at the same rate/proportion!
Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume). Therefore, the spacing between those tiny particles that make up the molasses is constant (does not change).
The size or amount of a material/substance does not affect its density.
