Two gases are in contact with each other so heat can flow between them. Assume no heat loss to surrounding. One gas is hot and the other gas is cold initially. Identify what happened to gases after the equilibrium condition?

Options

  1. AThe particles in the cold gas will have slowed in their rate of movement.
  2. BThe particles in the hot gas will have increased their rate of movement.
  3. CThe temperature of the cold gas will have decreased
  4. DThe temperature of the hot gas will have decreased

Correct answer

D. The temperature of the hot gas will have decreased

Step-by-step solution

In order to achieve equilibrium, heat from hotter gas starts flowing to the cold gas until their temperatures become the same. Therefore, due to the heat loss temperature of hot gas will have decreased.
