If iron melts at 1538 degrees and the earths core is at 5500 degrees why is it still a solid?

the 2 main variables which decide whether an element or compound is a solid, liquid, or gas, are temperature and pressure.
Iron melts at 1538 degrees only when it is pure (which the core is not) and under atmospheric pressure. The iron in the earths inner core is under pressure equivalent to many thousands (if not millions) times that of atmospheric pressure, so it exists as a solid.

Why does a ice cube stay at 0 degrees even though it is being heated up?
Latent heat. Ice absorbs heat when it melts, but it still stays at 0 degrees until its all liquid, then its temperature rises.
Why are no rocks found that date from the first 800 million years of earths existence?
Earth was too hot to have solid rocks at that time.
Malic acid is agt what form at 100 degrees Celsius?
At 100 degrees C, malic acid is still a solid. At 130 degrees C, malic acid will decompose and form carbon monoxide and carbon dioxide gases.
What is hotter inner mantle or outer mantle?
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
At room temperature a substance with a melting point of 40 Celsius is a?
Room temperature is 25 oC so it would still be a solid. It would be 104 degrees F... So. unless the substance's boiling point is below that, it would be a solid. otherwise it would be a gas.
What physical state of water -24 degrees Celsius?
Water freezes solid at 0 degrees Celsius, so it will still be solid at -24 degrees Celsius.
What happens when you dont put water in dry ice?
It still melts if it is above -110 degrees Fahrenheit.
What is the temperature at which a solid changes state into a liquid?
The condensation temperature is a characteristic of the gas that is different for ever gas or gas mixture. Atmospheric pressure and temperature differential also affects condensation temperature.
Is juice in freezer becoming solid a physical?
It is a physical change because nothing chemically happened to it. It just formed to solid but,it is still the same substance.When you take it out of the freezer it melts.
When a piece is heated Tia very high temperature melts into a liquid. Is it still a mineral?
no because it lacks the main factor its not a solid
What state is copper at 20 degrees celsius?
Solid still room temperature i think

What is the state of water at 0 degree celsius?
Short answer: Both solid ice and liquid water. Long answer: Once liquid water drops to 0 degrees Celsius, it is still liquid water. More heat energy has to be removed to transit water to a solid. This energy is called the "latent heat of fusion." That's why we often say water melts at 0 degrees Celsius (32 F) and water freezes at 0 degrees Celsius, because both are true. 333.55 kJ per kg are required to convert ice to liquid or vice-versa.
What state of matter is sodium chloride at 500 degrees Celsius?
Still sodium chloride.... In a solid form still. Molten NaCl occurs at 801C and above
Why are no rocks found that date from the first 800 million years of earths existence?
Earth was too hot to have solid rocks at that time.
Does solid iron have particles that move at 0 degrees c?
Yes, solid iron still contains particles that are in constant motion, even at 0 degrees Celsius. Although the motion is significantly reduced compared to higher temperatures, the particles still exhibit vibrational motion due to their thermal energy.
What is the state of 30 degree C?
It is still a solid but it is turning to be a liquid statesBromine boils at 58-590 C and melts at -70C so at 300 C it is a fuming reddish brown liquid.
