Does same temperature mean same internal energy?

You are correct. The relationship between energy and temperature is described by the “specific heat” of the material, and varies widely with both material and temperature. This is a correct statement.

When two systems have the same internal energy they must be at the same temperature?

Zeroth Law of Thermodynamics When two systems are in contact with each other and no energy flow takes place between them, then the two systems are said to be in thermal equilibrium with each other. In simple words, thermal equilibrium means that the two systems are at the same temperature.

Does internal energy vary with temperature?

But the internal energy of the system is still proportional to its temperature. Because the internal energy of the system is proportional to its temperature, internal energy is also a state function. Any change in the internal energy of the system is equal to the difference between its initial and final values.

Can two objects have the same thermal energy but different temperatures?

Identical masses of different materials can have different amounts of thermal energy, even at the same temperature. This means that the material that makes up the substance is a third factor that affects how much thermal energy a substance has.

Why internal energy is the same?

Internal energy is about all forms of energy (kinetic + interactions energies) in the system and temperature is only about kinetic energy. So, same temperature don’t means. always, same internal energy.

When you have two systems the energy transferred between the two has to remain the same?

The total change of energy in any system is always equal to the total energy transferred into or out of the system. This is called conservation of energy. Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems.

Why does internal energy only depends on temperature?

The meaning of “depend only on temperature” is that the internal energy of the gas does not change when it is allowed to expand into a vacuum. In that sense, the internal energy is independent of pressure and volume, and therefore dependent only on temperature.

How do you find internal energy from temperature?

All the heat that was necessary to heat the gas is finally present as internal energy U. Thus, at a temperature T the gas has the following internal energy U: U=cv⋅m⋅T applies in general to perfect gases!

What happens when two bodies have same temperature in contact Class 7?

As the temperature of the two bodies are same they are in thermal equilibrium which means there would be no transfer of heat energy between them.

How is thermal energy and temperature different?

Temperature measures the average kinetic energy of the particles in a substance. Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance’s temperature and thermal energy.

Can two bodies with the same internal energy have different temperatures?

Can two bodies having the same internal energy have different temperatures? According to me, two objects having the same internal energy may have different temperatures if their masses and specific heats are different and it is possible that an object with more internal energy may be at a lower temperature than the one with less internal energy.

What is the difference between internal energy and thermal energy?

They are different but related things. Thermal energy is that part of the internal energy that manifests as temperature via molecular motion. But internal energy is an extensive property of a system. The bigger the system, the more internal energy and thermal energy it has.

Why do two systems in thermal equilibrium not have the same energy?

The answer for both cases is that two systems in general do not have the same amount of energy if they’re in thermal equilibrium. This is because thermal capacitance and/or volume of systems might be different, that is, energy needed to raise the temperature of one system by one degree Kelvin is not the same as for the second system.

Do two objects with the same temperature have the same heat?

In most cases, the answer is yes: If you have two separate objects and they have the same measurable temperature, they also have the same thermal energy (heat).
