A physical change in matter caused by gain or loss of thermal energy is a change in state, such as melting or freezing. This occurs when the temperature of the substance reaches its melting or freezing point, causing it to transition between a solid, liquid, or gas state without altering its chemical composition.

How Does Thermal Energy Cause Change?
Thermal energy can cause changes in materials by either heating or cooling them. Heating can expand materials, change their physical state (e.g. melting), or initiate chemical reactions. Cooling can contract materials, change their physical state (e.g. freezing), or slow down reactions. Thermal energy essentially provides the energy needed for these changes to occur.
What are problems caused thermal energy?
Problems caused by thermal energy include overheating of electronic devices leading to reduced performance or damage, contributing to climate change through the release of greenhouse gases during energy production, and environmental impacts from thermal pollution in bodies of water, affecting aquatic ecosystems.
How is thermal energy of a substances related to its physical state?
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.
How can one determine the change in thermal energy in a system?
The change in thermal energy in a system can be determined by calculating the difference between the initial thermal energy and the final thermal energy of the system. This can be done using the formula: Q mcT, where Q is the change in thermal energy, m is the mass of the system, c is the specific heat capacity of the material, and T is the change in temperature.
What is the equation for meausuring the change in thermal energy?
The equation for measuring the change in thermal energy is: Q = mcΔT, where Q is the change in thermal energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
When an object increases in temperature it thermal energ y?

How the thermal energy of an object change when the objects temperature change?
when abody is heated definitely its thermal energy increases so far that it can even cause a change in its physical appearance
What energy is involved in ice changing to liguid?

Was the Hiroshima bombing a physical or chemical change?
At Hiroshima, the bomb itself was a nuclear weapon. The operative word there is nuclear. Nuclear changes brought about a massive release of that nuclear energy. The nuclear energy was converted into mechanical and electromagnetic energy, which resulted in the creation of a huge amount of thermal energy.The mechanical energy was carried outward in the blast wave. The combination of these things caused both physical and chemical changes, the latter owing to the electromagnetic and thermal (heat) energy.
What causes thermal energy?
Thermal energy is caused by the movement of particles within a substance. This movement generates heat energy by increasing the internal energy of the substance. The temperature of a substance is a measure of the average thermal energy of its particles.
