If two objects are in thermal equilibrium, do they have the same thermal or internal energy?

Physics

Tpy6a [65]3 years ago
7 0

Answer:

Yes, they do have the same internal energy.

Explanation:

The thermal balance refers to when there is no heat transfer between the bodies and their surroundings i.e. the bodies and the environment are at the same temperature.

Suppose two bodies of different masses and different materials, each one of them is at a temperature of 25(° C), which is the same temperature as the temperature of the environment, if these two bodies are close to each other, there is also heat transfer as they are at the same temperature, in the absence of any type of energy that enter or exit in these bodies, the amount of internal energy will be equal in both bodies.

Note: when the internal energy of one of these bodies is increased, heat transfer will happen, always looking for the thermal balance.

How can you tell there is only one atom of oxygen in H2O?
kow [346]

Answer:

For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen O, or ozone, a molecule of three oxygen atoms, O3.

What occurs during stage one sleep
Mekhanik [1.2K]

Answer:

Stage one of sleep, also known as the transitional phase, occurs when one finds themselves floating in and out of consciousness. During this NREM stage, you may be partially awake while your mind begins to drift off. This period of drowsiness eventually leads to a light sleep

Suppose you had the same laser and diffraction grating from the previous question but now you had a flat detection screen. You w
kolezko [41]

Answer:

measuring the zero intensity point, we can deduce the movement of the screen.

The distance from the center of the pattern to the first zero is proportional to the distance to the screen,

Explanation:

The expression for the diffraction phenomenon is

           a sin θ = m λ

for the case of destructive interference. In general the detection screen is quite far from the grid, let's use trigonometry to find the angles

           tan θ = y / L

     

in these experiments the angles are small

          tan θ = sin θ / cos θ = sin θ

          sunt θ = y / L

we substitute

          a \frac{y}{L}= m  λ

           y = m L λ / a

therefore, by carefully measuring the zero intensity point, we can deduce the movement of the screen.

 

The distance from the center of the pattern to the first zero is proportional to the distance to the screen, so you can know where the displacement occurs, it should be clarified that these displacements are very small so the measurement system must be capable To measure quantities on the order of hundredths of a millimeter, a micrometer screw could be used.
