Question

6. The melting point of iodine is 114°C and the boiling point is 183°C. What state will Iodine be at each of these temperatures:

70°C –
210°C –
185°C –
127°C –
0°C –

Answer 1

When an element is at a temperature that is higher than it's boiling point, it will be in gaseous form as it would have evaporated.

When the element at a temperature that is lower than it's melting point however, it would be in solid form as it would not have melted from it solid state yet.

70°C – Solid

Lower than melting point.

210°C – Gas

Higher than boiling point.

185°C – Gas

Higher than boiling point.

127°C – Liquid

Above it's melting point but below it's boiling point. It is a liquid at this point because it has melted but has not evaporated.

0°C – Solid

Lower than melting point.
