Measure the density.
Melting and freezing points
check solubility properties with some table salt
The smell Refractive index if you have the equipment.
you must evaporate it and see if anything is left behind and also run tests on it
Energy must be added to liquid water so that it reaches the boiling point, at which point the water will vaporize into water vapor.
If a liquid is poured into water and falls to the bottom the density must be greater than 1.
Mars has no liquid water. For a planet to have liquid water it must be the correct distance from the Sun like Earth.
To change from a gas into a liquid you must cool the substance. For example: water vapour to water.
To change from a gas into a liquid you must cool the substance. For example: water vapour to water.
Take In
No. A mineral must be solid to be a mineral. For example, liquid water is not a mineral. Frozen water, or ice, is a mineral.
No; water (as gas) must be cooled to become a liquid - this change is called condensation..
salt water,not pure water
he who alleges must prove
It must be. Minerals and salts are dissolved in the liquid, but do not react with the water. No reaction, no compound.
By boiling the substance, you can compare the actual boiling point of water in given conditions to that of the sample. However, analogues can be made which will have an identical boiling point, yet contain little or no water at all. Hence, boiling alone cannot ascertain what something is. This holds for all physical tests - you must use chemical tests as well to determine exactly what composes a sample.
