Water is only a liquid in its liquid form, when it is frozen it becomes a sold and when it evaporates it becomes a gas
Only Earth is thought to have liquid water.===================================Updated informationIn 2015, NASA presented what they consider definitive evidence that there is some liquid water on Mars.
One way to determine if the liquid is water is to consider the temperature at which the liquid boils. Water has a boiling point of 100 degrees Celsius or 212 degrees Fahrenheit.
Let's consider the case of ice. Ice is a solid. When heated, it gets transformed to water. Water is a liquid. Further heating changes water into gas. Thus, heat can change a solid into both liquid and solid form.
When choosing a solvent for liquid-liquid extraction, factors to consider include the solubility of the target compound in the solvent, the selectivity of the solvent to the target compound, the density difference between the two phases to aid in separation, and the cost and toxicity of the solvent. For extracting benzoic acid from water, a suitable solvent might be ethyl acetate, as it has a good solubility for benzoic acid and can be separated easily due to its density difference with water.
You can separate them using chromatography.
These persons consider for example liquid water and water vapors as different substances.
When this component is in the liquid state.
A liquid. It's a frozen liquid. It's like ice, it's frozen water. It melts in your mouth, so does ice cream.
Water vapor is different from liquid water because water vapor is a gas, and liquid water is a liquid.
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
Rain is a liquid because it is water.
Water Vapor is technically a gas and Liquid water is obviously a liquid.
