The two insulated beakers contain equal amounts of identical liquids. The temperature of Beaker A is 80°C. The temperature of Beaker B is 50°C. A copper rod connects the beakers. The system is then left alone for several hours. What would you expect to find when the system is examined after this time?
A. The temperature of Beaker A would be 50°C and the temperature of Beaker B would be 80°C.
B. The temperatures of the two beakers would be unchanged.
C. Both of the beakers would be at a temperature of 50°C.
D. Both of the beakers would be at a temperature of 65°C.
i think the answer is a
is this answer correct?
To determine the expected outcome of the system after several hours, we can use the principle of thermal equilibrium and the process of heat transfer to analyze the situation.
When the copper rod connects the two beakers, heat will flow from the higher temperature (80°C in Beaker A) to the lower temperature (50°C in Beaker B) until thermal equilibrium is reached. This process is known as conduction, whereby heat transfers from one object to another through direct contact.
Since both beakers contain equal amounts of identical liquids, the heat transfer between them will continue until they reach the same temperature.
Therefore, the expected outcome when the system is examined after several hours is option C: both of the beakers would be at a temperature of 50°C.
