To determine the changes of state involved in the use of ethyl chloride, we need to examine the boiling point and freezing point of ethyl chloride.

1. Liquid to gas: Ethyl chloride boils at approximately -14.8 °C, so when it is heated above this temperature, it changes from a liquid to a gas. Therefore, this change of state is applicable.

2. Liquid to solid: Ethyl chloride does not solidify at temperatures commonly encountered, so it does not undergo the change from a liquid to a solid under normal conditions. Therefore, this change of state is not applicable.

3. Gas to solid: Since ethyl chloride does not solidify at normal conditions, it cannot change directly from a gas to a solid. Therefore, this change of state is not applicable.

4. Liquid to solid: We have already established that ethyl chloride does not undergo this change of state.

5. Solid to liquid: Ethyl chloride does not exist as a solid at normal conditions, so it cannot change from a solid to a liquid. Therefore, this change of state is not applicable.

6. Solid to gas: Since ethyl chloride does not solidify at normal conditions, it cannot change directly from a solid to a gas. Therefore, this change of state is not applicable.

Based on this analysis, the correct changes of state involved in the use of ethyl chloride are:
1. Liquid to gas (option 1)
