Table salt
Sugar
Iodine
Potassium Iodide
Answer is Right!
Answer is Wrong!
The correct answer is C. Iodine.
Sublimation is the process of a substance passing directly from the solid to the gaseous state without passing through the intermediate liquid state.
Table salt (NaCl) is a crystalline solid that melts at 801 degrees Celsius. When heated, it melts into a liquid and then boils into a gas.
Sugar (C12H22O11) is a crystalline solid that melts at 186 degrees Celsius. When heated, it melts into a liquid and then boils into a gas.
Potassium iodide (KI) is a crystalline solid
that melts at 681 degrees Celsius. When heated, it melts into a liquid and then boils into a gas.Iodine (I2) is a solid that sublimes at 113.7 degrees Celsius. This means that when it is heated, it goes directly from a solid to a gas without melting.
Iodine is the only substance listed that sublimes.
