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.
What else can I help you with?
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 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.
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.
What Can cause kinetic energy to change to thermal energy?
Friction can cause kinetic energy to change into thermal energy
What is the change in the combined thermal energy of the slide and the seat of her pants?
The change in the combined thermal energy of the slide and the seat of her pants refers to the overall increase or decrease in heat energy in both objects.
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 is the increase in thermal energy of a cylinder related to the vertical falling distance?
The increase in thermal energy of a cylinder is not directly related to the vertical falling distance. The thermal energy change is primarily influenced by factors such as the material and mass of the cylinder, initial temperature, and heat transfer mechanisms. The falling distance may affect the kinetic energy of the cylinder, but this does not have a direct impact on its thermal energy change.
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.
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.
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.
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
When concrete hardens it gives off thermal energy does the concretes temperature change?
Yes, when concrete hardens it undergoes an exothermic process which means it releases heat. This release of thermal energy can cause the temperature of the concrete to increase during the hardening process.
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
When dry ice disappears does the thermal energy decrease or increase?
i think the thermal energy increases because thermal energy is the energy which is due to the movement of particles, so when the the particles are released there is more thermal energy(they against each other).
What is one kind of energy produced during a chemical change in matter?
For example thermal energy.
