Solution

When steam is converted into water, the process is known as condensation. This is an exothermic process, meaning it releases heat.

Here are the steps to understand how the internal energy of the system changes:

  1. The steam (water in its gaseous state) has a higher level of internal energy because the molecules are moving rapidly and are far apart from each other.

  2. When steam is converted into water, it goes from a higher energy state (gaseous) to a lower energy state (liquid). This means the steam loses energy.

  3. The lost energy is released as heat. This is why condensation is an exothermic process.

  4. Therefore, the internal energy of the system decreases when steam is converted into water.

In conclusion, the internal energy of the system decreases when steam is converted into water.
