Question

A copper rod connects two insulated beakers that contain liquids. The temperature of the liquid in Beaker A is 85°C and
the temperature in Beaker B is 15°C. Over the next 60 seconds, what will occur?

Answer 1

Explanation:

Over the next 60 seconds, the water in the beaker will try to attain thermal equilibrium by bringing the temperature in both beaker to the same level.

• Heat generally moves over a gradient from a place of higher temperature to one with lower temperature.
• The copper rod is a metallic conductor.
• Heat will flow from the beaker at 85°C to the beaker at 15°C
• During the passage of time, the liquids in both beaker will reach thermal equilibrium and the temperature will be the same.
