The water vapor from the hot shower is condensing on the colder surface of the mirror. That is a physical change.
The droplets you see on the mirror after taking a shower are a result of both physical and chemical changes.
Let's start with the physical change. When you take a hot shower, the water vaporizes and turns into steam due to the high temperatures. The steam rises and comes into contact with the cooler surface of the mirror. As the steam cools down quickly, it undergoes a physical change called condensation. The water vapor in the air transforms into liquid water droplets on the surface of the mirror. This process occurs because the mirror is colder than the steam, causing the water vapor to lose heat and change its physical state.
Now, let's discuss the chemical change. While the process of condensation is a physical change, the formation of the water droplets on the mirror also involves a chemical change. When water vapor condenses, it forms liquid water due to the attraction between water molecules. The bonds between the water molecules break, and new bonds form as the molecules rearrange themselves to become liquid water droplets on the mirror surface.
To summarize, when hot steam from your shower comes into contact with the colder mirror surface, it undergoes a physical change called condensation, transitioning from a gaseous state to a liquid state. This condensation process involves both physical and chemical changes as the water vapor rearranges its molecular structure to become liquid water droplets.
