Thermal energy refers to the total change in energy of an object as temperature changes while temperature tells us only about the change in kinetic energy of the constituent atoms and molecules.
The temperature of an object is a direct measure of the kinetic energy of the atoms and molecules that make up the object. The connection between the temperature and average translational kinetic energy of atoms and molecules in a material is given by an equation,
KE(averaged)=3/2kT,
where the kinetic energy is the usual one half mass times velocity squared of all the molecules or atoms in a material at the temperature T. T is measured as the temperature above absolute zero. The letter k stands for the Boltzmann constant.
In addition to translational kinetic energy, there is also rotational kinetic energy and vibrational kinetic energy in molecules. Those too are simply proportional to temperature with a similar equation.
Thermal energy is more than kinetic energy. It also includes potential energy. In a solid, there is also electronic energy to be considered. If the material is not a simple collection of atoms and molecules, thermal energy may also include energy associated with chemical changes.
In summary, we normally use the term thermal energy to describe the energy acquired by an object when heated. Temperature, on the other hand, is simply related only to that part of the energy associated with the motion of the atoms and molecules, i.e. the kinetic energy as described above.
Caveats:
1. This answer ignores quantum effects that alter the relationship to kinetic energy at extremely low temperatures, near absolute zero. It ignores extremely high temperature effects where normal matter may be transformed in the plasma state. What is said here is correct for normal materials encountered by people in everyday life.
2. One should properly be discussing so-called "free energy" such as Helmholtz free energy or Gibbs free energy, but that is more in the technical arena of thermodynamics.

How does temperature differ from thermal energy and what is the relationship between the two?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. The relationship between temperature and thermal energy is that an increase in temperature usually leads to an increase in thermal energy, as the particles move faster and have more energy.
How do thermal energy and temperature differ?
Thermal energy refers to the total kinetic and potential energy of particles within a substance, whereas temperature is a measure of the average kinetic energy of those particles. Thermal energy depends on the amount of matter present, while temperature is an intensive property that does not depend on the size of the system.
In what ways is temperature distinct from thermal energy and how do they differ from each other?
Temperature and thermal energy are related concepts but are distinct from each other. Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. In other words, temperature is a specific measurement of the average energy of particles, while thermal energy encompasses the total energy of all particles in a substance.
Is the thermal energy that flows from one substance to another when the substances differ in temperature?
Yes, thermal energy flows from a substance with a higher temperature to a substance with a lower temperature. This transfer of energy is known as heat transfer and occurs until thermal equilibrium is reached between the two substances.
How is thermal energy and temperature same?
Thermal energy and temperature are related but not the same. Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. In other words, temperature is a single value, while thermal energy is a total amount of energy.
How is thermal energy different from temperature How are they similar?
temperatures differ from thermal energy because differ because thermal energy is the total energy of all particles in an object and temperature is a measure of the average energy of random motion of particles of matter.

How are thermal energy and temperature similare?
Temperature is what is used to measure thermal energy The more thermal energy a substance has, the more warmer it will be. So when the temperature is high, there is a lot of thermal energy Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement
How are temperature and thermal energy related?
we use thermal energy by measuring temperature

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.
When thermal energy is removed from matter what happens to its temperature'?
When thermal energy is removed from matter, its temperature decreases. This is because temperature is a measure of the average kinetic energy of particles in a substance, so removing thermal energy reduces the kinetic energy and hence the temperature.
What container has more thermal energy?
The container that has more thermal energy would be the one with a higher temperature. Thermal energy is directly proportional to temperature, so the container with a higher temperature would have more thermal energy.
How does temperature form thermal energy?
It doesn't, Temperature is a MEASURE of the thermal energy state of something.
