A copper rod 81 cm long is used to poke a fire. The hot end of the rod is maintained at 105 °C and the cool end has a constant temperature of 21 °C. What is the temperature of the rod 25 cm from the cool end?
Step 1 of 3
To calculate the temperature of a rod at a particular point.
The heat flow through a rod whose ends are kept at different temperatures is proportional to,
Where, - Area of cross section
- Change in temperature
- Length of the rod
- Time of heat flow
