No way!
Density = mass / volume. So if the volume changes, the density will obviously also change.
Density = mass / volume. So if the volume changes, the density will obviously also change.
The density of water changes at different temperatures. As temperature goes up, density goes down.
Changing the mass or volume of an object changes its density. Density is defined as the mass of an object divided by its volume, so if either the mass or volume changes, the density will change accordingly.
No. Mass never changes, except during nuclear fission and fusion.
The only way to change the mass of water would be to either add more of it (which wouldn't change it's density - density is an intensive property, not extensive) or to change the isotopes of hydrogen and oxygen in the water - thus getting "heavy water" such as is present as an intermediate materiel in the refining of tritium and as a moderator in some nuclear reactors.
No, a change in mass alone does not affect the density of an object. Density is determined by the mass of the object and the volume it occupies, so changes in mass need to be accompanied by corresponding changes in volume to affect an object's density.
No, your density does not change when you are in water. Your density is determined by your mass and volume, and it remains constant regardless of the medium you are in.
Yes, the density of water changes when it is converted into steam because the molecules spread out and the volume expands to fill its container while the mass of the water remains the same. Since the volume increases and the mass remains constant the density greatly decreases.
If you change the mass of a fluid while keeping the volume constant, the density of the fluid will change. Density is calculated as mass divided by volume, so if the mass changes but the volume stays the same, the density will increase if the mass increases and decrease if the mass decreases.
Actually no, the only thing that changes is the density. The mass doesn't change when it's changing states.
Mass is conserved. Volume changes slightly, so density changes as well, but mass remains the same.
