A kind of matter which can sublime is
A kind of matter which can sublime is
The correct option is D (d) iodine
correct answer explanation:
(d) iodine:
- There are some substances that directly change from the solid-state to the gaseous state without passing through the liquid state. These substances are called sublimable or sublime substances and their conversion is known as sublimation.
- Iodine while on heating directly converts from the solid state to the gaseous state without coming through the liquid phase.
incorrect answer explanation:
(a) water: It is present in liquid form, when we supply heat to a liquid substance it converts into gas. Hence it is not a sublime substance.
(b) plastic: It is present in solid form. When plastic is heated, it converts into liquid form.Hence it is not a sublime substance.
(c) milk: It is present in liquid form, when we supply heat to a liquid substance it converts into gas and the proteins or fats remain left behind. Hence it is not a sublime substance
Concluding substance: The substances that directly change from the solid-state to the gaseous state without passing through the liquid state. These substances are called sublimable or sublime substances. Hence option (d) iodine is the correct answer ( it is a sublime substance).
