# Its sensible temperature can increase, # It can undergo a phase change (solid->liquid, liquid->gas, gas->plasma, or solid->solid with atomic arrangements), or # A chemical / physical reaction can be triggered (diffusion in semiconductors, curie temperature in magnets, have a pretty sharp temperature thresholds).

What will happen to the state of the substance the atomic or molecular activity and the shape of the graph when thermal energy is added?
When thermal energy is added to a substance, the atomic or molecular activity will increase, leading to higher kinetic energy of the particles. This results in the substance changing states from solid to liquid, and then to gas, if the temperature continues to rise. The shape of the graph will show an increase in temperature with corresponding changes in state, known as phase transitions.
When heat is added or removed from a substance where is the thermal energy going?
When heat is added to a substance, the thermal energy increases the kinetic energy of the particles in the substance, causing them to move faster. When heat is removed, the thermal energy decreases, and particles slow down. Therefore, the thermal energy is transferred to or from the particles in the substance, changing their motion and temperature.
What is happening to a substance undergoing thermal energy?
As thermal energy is added to a substance, its temperature increases, causing its molecules to move faster and vibrate more. This can lead to changes in state, such as melting or boiling, depending on the substance and the amount of thermal energy being added.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.
When energy is added to molecules what happens to the substance?
they spread apart and move faster when energy is added.

How will a substance change if energy is added to the liquid at 20 degrees Celsius?
The substance will get hawter

What means energy is added to the substance as it changes state?
it vaporizes

Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
The temperature of the substance will increase when thermal energy is added without changing state. This is because the thermal energy is causing the particles within the substance to move faster, resulting in an increase in temperature.
What happens to the particles when thermal energy is added or removed?
When thermal energy is added to a substance, the particles gain kinetic energy and move faster, increasing the substance's temperature. When thermal energy is removed, the particles lose kinetic energy and slow down, causing the temperature to decrease.
Why does evaporation require that heat energy be added to a substance?
Evaporation requires heat energy to be added because it provides the molecules in a substance with enough kinetic energy to overcome the attractive forces holding them together. As molecules gain energy, they move faster and escape the liquid phase, transitioning into the gas phase. This process leads to evaporation.
Sometimes heat energy is added but the temperature stays the same when is this?
When a substance undergoes a phase change, such as melting or boiling, heat energy is added, but the temperature remains constant. This is because the added energy is being used to break the intermolecular forces holding the substance together, rather than increasing the kinetic energy of the particles.
