Furthermore, how do you calculate mass from water volume?
Once you know specific gravity, you also know density, because you just multiply specific gravity by the density of water, which is 1 gm/cm3, to get density. You can then find the mass of a specific volume of the liquid by multiplying its density by the volume of the liquid you have.
Secondly, does heating increase mass? Heating does not increase mass. Heating increases internal motion of molecules, so the energy imparted by heating is embodied as kinetic energy. An object does not become heavier because it is in motion. However, kinetic energy can be converted to mass.
In this way, is the mass of water the same as its volume?
Water molecules all have the same mass and size. No matter what size sample of water you measure, the relationship between the mass and volume will always be the same. Because D=m/v, the density is the same for any amount of water.
How does temperature affect the movement of water?
Temperature causes water molecules to move more quickly, because each individual molecule has more energy as it gets hotter (according to Kinetic molecular theory). If you get water hot enough, the molecules move so much that the hydrogen bonds that hold them together start to break and the water becomes a gas
