Interpretation:Comprehend the terms sublimation and evaporation.
Concept Introduction: Matter can exist in three possible
Solids are the substances with least intermolecular distance and strongest intermolecular forces whereas gases have largest intermolecular distance and weakest intermolecular forces.
Liquids have intermediate value of intermolecular distance and intermolecular forces.
These states of matter can interconvert into each other and is called as interconversion of states of matter.

Answer to Problem 3E
Sublimation can be defined as the process of conversion of solid to gaseous state. Evaporation is the conversion of liquid to gaseous state.
Explanation of Solution
The different interconversions of states of matter are:
- Melting- Conversion of solid to liquid
- Evaporation − Conversion of liquid to gas
- Condensation − Conversion of gas to liquid
- Sublimation − Conversion of solid to gas
- Freezing − Conversion of liquid to solid
Thus Sublimation can be defined as the process of conversion of solid to gas without changing to liquid state like conversion of dry ice to gaseous carbon dioxide is a sublimation process.
Evaporation is the process of liquid to gas like heating of water forms water vapor.
- Evaporation − Conversion of liquid to gas
- Sublimation − Conversion of solid to gas

- How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right.

Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х аarrow_forward
