Question

t_i = 300 k t_i = 100 k what is a possible temperature of the system after the divider has been removed? 325 k 75 k 185 k

Explanation:

Step1: Analyze Heat Transfer

When the divider is removed, heat transfers from the hotter system (300 K) to the colder one (100 K) until thermal equilibrium. The final temperature should be between 100 K and 300 K.

Step2: Evaluate Options

• 325 K > 300 K: Impossible (hotter than initial hot system).
• 75 K < 100 K: Impossible (colder than initial cold system).
• 185 K is between 100 K and 300 K: Valid.

Answer:

185 K
