Answer 1

When silver (Ag) is heated and changes from a solid to a liquid, the correct representation of this phase change is as follows:

- **Ag (s) → Ag (l)** (solid to liquid)

This can be expressed in the context of the options provided:

1. **Ag (g)** (gas) is not relevant to the phase change from solid to liquid.
2. **Ag (s) ⟶ Ag (l)** (solid to liquid) is correct.
3. **Ag (liquid) ⟶ Ag (solid)** is incorrect as it describes the reverse phase change (liquid to solid).
4. **Ag (solid) ⟶ Ag (liquid)** is correct.

Therefore, the correct options are:

- **Ag (s) ⟶ Ag (l)**
- (As a separate representation) **Ag (solid) ⟶ Ag (liquid)**
