How can you tell if two objects are in thermal equilibrium?

The objects are the same size.

The objects' temperatures are changing.

The objects have the same temperature.

The objects are touching each other.

Respuesta :

Answer: Option (c) is the correct answer.

Explanation:

When two substances does not exchange any energy with each other then they are said to be in thermal equilibrium with each other.

This means the temperature of both the substances will be equal, that is why, there is no exchange of energy between them.

Thus, we can conclude that when the objects have the same temperature then you can tell the two objects are in thermal equilibrium.

The correct answer is "The objects have the same temperature."

If two objects are in thermal equilibrium both will have the same temperature. Heat flows from a hot to a cold body. Only in the absence of a thermal equilibrium, heat will flow from a body at a high temperature to a body at low temperature. As heat keeps flowing between the hot and cold bodies, finally both will achieve the same final temperature. This is when the two bodies are at thermal equilibrium .
