Explain what will happen when cold water is placed in a sealed room after an amount of time and what type of system is it ?

- Water's temperature will be in equilibrium with the surrounding temperature.

- Closed system.

Explanation:

Hello,

In this case, in thermodynamics we define a sealed room as a closed system (matter neither leaves nor enters to the system) which allows the energy transfer as it is not isolated. In such a way, as time goes by, the water will exchange energy with the surroundings in order to attain the thermal equilibrium (equal temperature for both water and surroundings). Thus, if the surroundings are hotter than the cold water, it will heat up until equilibrium temperature. Moreover, if the surroundings are colder than the water, it will cool down until equilibrium temperature.

Best regards.

idk what the question is about
