Current Question (ID: 10801)

Question:

\text{The temperature of the hot and cold ends of a 20 cm long rod in a thermal steady state is at } 100°\text{C and } 20°\text{C respectively. The temperature at the centre of the rod will be:}

Options:

1. $50°\text{C}$
2. $60°\text{C}$ (Correct)
3. $40°\text{C}$
4. $30°\text{C}$

Solution:

\text{Temperature gradient} = \frac{100-20}{20} = 4^\circ\text{C/cm} \text{Temperature at centre} = 100 - 4 \times 10 = 60^\circ\text{C}
