What effects can occur when heat energy is added to a system?
Since this is not my area of expertise, I searched Google under the key words "add heat energy" to get these possible sources:

When heat energy is added to a system, several effects can occur. Here are a few possible effects:
1. Temperature increase: The most common effect of adding heat energy is an increase in temperature. Heat is a form of energy that causes the atoms or molecules in the system to vibrate faster, leading to an overall rise in temperature.
2. Phase change: If the heat energy added causes the system to reach its boiling or melting point, a phase change can occur. For example, solid ice can melt into liquid water when heat is added, or liquid water can vaporize into steam.
3. Expansion: Many substances expand when heated. This is because the heat energy causes the atoms or molecules to move more vigorously, increasing the average separation between them. This expansion effect can be observed in various materials, such as metals, liquids, and gases.
4. Chemical reactions: In some cases, adding heat energy to a system can initiate or accelerate chemical reactions. The increased molecular motion can provide the necessary activation energy for a chemical reaction to occur.
To understand these effects and their specific consequences for a particular system, you can use thermodynamics principles and knowledge of the specific properties of the materials involved. This includes understanding heat capacity, phase diagrams, and chemical reactions. Experimental observations and data can also be helpful in analyzing these effects.
