Answer:
D. Pressure and temperature.
Explanation:
The answer is D because when water molecules (H2o) have heat and pressure added it will boil. For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.
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
Nitrogen and oxygen do not react at ambient temperature. At high temperatures they have endothermic reactions and produces various oxides of nitrogen.
Explanation:
The difference between nitrogen and oxygen is the nitrogen has seven protons and seven electrons surrounding the nucleus. Whereas the oxygen has eight protons and electrons.
The atoms combines with one another to form molecules. The nitrogen is a inert, colorless gas with no smell or taste, its harmless to human beings.
The oxygen and nitrogen are abundant gases in the atmosphere and have similar physical properties. The oxygen (O2) is twice as soluble in water as nitrogen (N2).
