| An organic compound ‘X’ has a melting point of - \[33{}^\circ C\] and a boiling point of \[66{}^\circ C.\] |
| The physical states of substance ‘X’ at temperature - \[100{}^\circ C,\] \[0{}^\circ C\] and \[100{}^\circ C\] are respectively |
A) solid, liquid and liquid
B) liquid, solid and liquid
C) solid, liquid and gas
D) gas, liquid and liquid.
Correct Answer: C
Solution :
Substance exists as a liquid between \[\text{-33 }\!\!{}^\circ\!\!\text{ C}\] to \[\text{66 }\!\!{}^\circ\!\!\text{ C}\](;.e., at \[\text{0 }\!\!{}^\circ\!\!\text{ C}\]). At \[\text{-100 }\!\!{}^\circ\!\!\text{ C}\], it will be a solid and at \[\text{100 }\!\!{}^\circ\!\!\text{ C}\], it will be in gaseous state.
