A unknown liquid 'X' has a freezing point of $-38^\circ ext{C}$ and a boiling point of $357^\circ ext{C}$. At room temperature ($25^\circ ext{C}$), in which state of matter will 'X' exist?

Question

A unknown liquid 'X' has a freezing point of $-38^\circ	ext{C}$ and a boiling point of $357^\circ	ext{C}$. At room temperature ($25^\circ	ext{C}$), in which state of matter will 'X' exist?

Aicharya · Accepted Answer

Since $25^\circ	ext{C}$ lies between its freezing point ($-38^\circ	ext{C}$) and boiling point ($357^\circ	ext{C}$), the substance exists in liquid state.

A unknown liquid 'X' has a freezing point of $-38^\circ\text{C}$ and a boiling point of $357^\circ\text{C}$.…
