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.
a change of state
Thermal.
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
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.
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.
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
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.
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.

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.
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.
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.
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.
For example thermal energy.
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 the total energy of the particles in a substance affect the thermal energy of the substance.
Friction can cause kinetic energy to change into thermal energy
