Question
The melting point of iron is 1538o Celsius. What is the state of iron at 1400o degrees Celsius?
- Solid
- Liquid
- Gas
- None
Hint:
Matter can change its state Upon heating or cooling.
The correct answer is: Solid
- Solid can only change its state to liquid above its melting point
- So at 1400 degree celicius iron will be a Solid
