Heat is the intrinsic energy of a piece of matter. If it is least the body is solid, liquid if it is more & gas if it is most. The motion of the molecules in the body determines it. Mostly the molecules due to attractive forces & ordering in space are tightly bound in a solid giving it the rigidity & shape. When they acquire sufficient energy to move about freely, yet held within the body (due to interaction of attractions that makes the surface of the liquid) it is liquid. But when the motion & velocity is such as to break the molecules free from each other it becomes a gaseous body. Heat is the measure of average kinetic energy of the molecules.

∙ 15y agoa change of state usually means a change from a solid-liquid, liquid-gas, liquid-solid, solid-gas. Thermal energy uses heat which helps the changes of the matter state. With that information if the thermal energy changes so will the speed of the change of state.

When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
How are states of matter and changes in energy related?
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
Does thermal energy increase during a phase change?
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.
Describe potential energy?
Potential energy is a fundamental concept in physics and plays a crucial role in understanding the behavior of physical systems and the conservation of energy. When the conditions or positions of objects change, potential energy can be converted into other forms of energy, such as kinetic energy or thermal energy, as objects move or undergo changes in their state.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What happens to a substance as its thermal energy increases?
if temperature changes that means there is thermal energy in a substance
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
Explain what happens when we suply heat and energy to water till it change its state What is this eat energy called?
When water has heat and energy it changes energy. The energy that it changes to is called thermal.
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 are states of matter and changes in energy related?
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
How is the state of mattr related to the amount of energy in a substance?
When thermal energy is added or removed, the state of matter changes to another solid that becomes liquid and the liquid becomes gas
How does energy impact a change of state?
What kind of energy is involved when the matter changes state?
What is the temperature at which a solid changes to a liquid called is there a gain or a loss of energy?
this process is the process of gaining thermal energy. As any matter changes state from solid to any other form it will require energy. As energy is exerted on the solid perssure or electric or thermal or other type, the solid will obsorb the energy and change state. The solid thereby will in turn and at a ratio, increase the thermal energy it consumes.
Which of the following changes of state releases thermal energy A. Melting C. condensation B. Sublimation D. evaportion?
C) Condenstation
How does temperature form thermal energy?
It doesn't, Temperature is a MEASURE of the thermal energy state of something.
What is absorbed or released when matter changes from one state to another?
yes. Matter can change state when thermal energy is absorbed or released.
