I think the last one but I’m not sure
Answer:
mixture
Explanation:
Chromatography separates components of a material based on their difference in polarity. Since the chromatography experiment resulted in more than one mark appearing, there must be more than one component in the material.
Upon standing for 24 hours, the liquid ink separates into its different components based on their differing properties, such as density or solubility. Since a pure substance is homogeneous and has the same properties throughout, the ink cannot be a pure substance.
1. We might run out of water faster
2. People might not have enough water
3. Animals will be really thirsty because all the water was used on the grass
4. It might flood if the grass doesn't soak in the water fast enough
Water is another example of a chemical compound<span>. The two or more component elements of a </span>compound<span> can be separated through chemical reactions. </span>Chemical compounds<span> have a unique and defined structure, which consists of a fixed ratio of </span>atoms<span> held together in a defined spatial arrangement by chemical bonds.

Lower temperature
Let's verify
- Pressure=P
- volume=V
- Temperature=T
As per Boyles law
As per Charles law
So
At higher altitudes lower the pressure so lower the temperature
