Thermal energy may increase or decrease during a phase change. It depends on which "direction" the change is going. In a phase change between a solid and liquid, as in the case of water, the solid water (ice) will reach 0 °C by absorbing thermal energy. It's temperature will be rising as it absorbs heat. But at the transition temperature, it must still absorb some heat to "make the transition" from ice at 0 °C to water a 0 °C. This thermal energy is the enthalpy of fusion. Thermal energy will have increased during the phase change. Another way make the point is that water at 0 °C will have more thermal energy than an equal mass of ice at 0 °C. If you guessed that the opposite is true, you'd be correct. The changes in thermal energy apply to "regular" phase changes between solids, liquids and gases. (There are other types of phase change that don't involve thermal energy or the change of state from solid, liquid or gas.) A link can be found to the enthalpy of fusion for you to investigate further into this one type of transition. That link is below.

The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
Which form of energy is almost always produced during energy transformations?
Thermal.
What causes some mechanical energy to change to thermal energy?
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
How is heat different from thermal energy?
There is no particular difference between heat and thermal energy. Heat is a form of thermal energy. Since thermal energy is energy from heat, heat and thermal energy are basically the same thing.
How is the rate of a cooling of a building affected by the thickness and the thermal conductivity of its walls?
Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.
What happens to the thermal energy of a substance during a change of state?
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
Is it possible to apply thermal energy to an object and the temperature not increase?
Oh yes, that is possible. Thermal energy can cause a change of phase, during which the temperature does not increase. So when water boils, it remains at 100o Celsius until it is all boiled away.
How does change in thermal energy causes matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
How are thermal energy and temperature alike?
If you increase temperature you increase thermal energy.If you double the amount you have the temperature does not change but the thermal energy does.Temperature and thermal energy are the same since they both use kinetic energy. Temperature uses the thermal energy when the heat measures the average of the kinetic energy. The thermal energy uses the kinetic energy, when it's averged together with the kinetic enery and the others to make the thermal energy.==========================Answer #2:Wow !Temperature is to thermal energy as depth is to water.
What happens to the thermal energy of a substance during a physical change of state?
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
How does in thermal energy cause matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
How Does Thermal Energy Cause Change?
An increase in thermal energy gives particles more kinetic energy, which causes them to vibrate more. As they vibrate more, the volume they take up increases.
What heppens to matter when you add thermal energy?
When you add thermal energy to matter, either the temperature will increase, or there will be a change in the state (phase) of matter, for example when ice melts.
What is one kind of energy produced during a chemical change in matter?
For example thermal energy.
How does the thermal energy of a system change when work is done on The system?
Usually the "thermal energy" will increase since work ON the system adds energy. Thermal energy is really not the best term though. A much better term in thermodynamics would be ENTHALPY.
How does an increase in total energy of the particles in a substance affect the thermal energy of the substance?
How does an increase in the total energy of the particles in a substance affect the thermal energy of the substance.
What can cause kinetic energy to change into thermal energy?
Friction can cause kinetic energy to change into thermal energy
