Because it is extremely hot.
Melting Point: 155 °C (311 °F; 428 K)
Explanation:
The melting point of ammonium phosphate is 155 °C (311 °F; 428 K). The melting point is the temperature at which a compound will melt.
It is a physical property of most substances usually determined in the laboratory.
- Most solids, especially ionic salts have very high melting points.
- Ammonium phosphate is no exception.
- It is one of the key ingredients used in making plant fertilizers to ensure they grow properly.
- It is a white grain substance.
- It is an unstable compound made up of ammonium and phosphate salts.

In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
<span>Heat would make the molecules move faster so they would spread out therefore making air less dense.
Less dense means less packed. Heat increase the kinetic energy</span>
Carbon bound in fossil fuels has different isotopes than carbon in atmosphere. Fossil fuels are underground and cosmic rays do not affect carbon in them same as atmosphere carbon. Carbon in fossil fuels that is underground longer than ten thousand years has only C-12 isotope and not C-14.
