it will increase or decrease depending on the states.
from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing
from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
It depends on what state it will turn. The thermal energy will be constant during the change of state because the energy its using will remain at the substance.
The thermal energy changes but the temperature remains the same. All of the energy guess into changing state and not into changing the temperature.
The temperature remain constant.
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
it means figure it out yourself!

PHYSICAL CHANGE - refers to the change in size, shape, or state of matter. CHEMICAL CHANGE - happens when one chemical substance is transformed into one or more different substance, such as iron becomes rust.
it would be physical change because physical change is when the substance stays the same
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.

Physical change

I want to say physical change
The Substances die

there is to types of change to a substance chemical and physical in a physical change the result is a mixture also most times you can change your end result into what you started with e.g.freeze-melt evaporate-condesate

a physical change is a change in any physical property of a substance, not in the substance itself
