Consider two equal size rooms connected by an open door. One room is maintained at a higher temperature then the other one. Whic
patriot [66]

Answer:

  • The room mantained at a lower temperature will contain more air molecules.

Explanation:

1) Since the two rooms are <em>connected by an open door</em>, you assume pressure equilibrium: the pressure on the two rooms is the same.

2) Since you consider <em>two equal size rooms</em>, both volumes are equal.

3) Assuming ideal gas behavior, pressure (P), temperature (T), volume (V) and number of moles (n) are related by the equation PV = nRT

4) Naming T₁ the lower temperature, T₂ the higher temperature, n₁ the number of moles of air in the room at lower temperature, and n₂ the number of moles of air in the room at higher temperature, you get:

  • n₁ T₁  = n₂ T₂, or n₁ / n₂ = T₂ / T₁

5) That means that the amount of molecules (number of moles) is inversely related to the temperature: the higher the temperature the lower the number of moles, and the lower the temperature the greater the number of moles.

Hence, the answer is that <em>the room that contains more air molecules is the room mantained at a lower temperature.</em>
