17. A student places the ends of a curved copper bur into two insulated cups, as shown below. The copper
barist 20°C Cup 1 contains 40°C water and cup 2 contains 20°C water. Each cup contains the same
amount of water
Copper bar
Cup 1
Cup 2
20°C
A Describe the direction of heat flow between the cups of water in the first few minutes of the
Investigation and identify the primary method of heat transfer (conduction, convection, radiation)
between the cups of water. Make sure to describe how the transfer of heat occurred for the method you
identified
The direction of heat flow in the first few minutes is not to cold. The primary
method of heat transfer is conduction because the copper is in between the te
cups of water

B. After 25 minutes, the water in both cups reaches thermal equilibrium. Calculate the temperature at
which thermal equilibrium is reached.
