The temperature gradient in a rod of 0.5 m length is 8 0 ∘ C/m. If the temperature of the hotter end of the rod is 3 0 ∘ C, then the temperature of the cooler end is:

The difference across the rod is 80 × 0.5 = 4 0 ∘ C. The cooler end is at 30 − 40 = − 1 0 ∘ C. B.

The temperature gradient in a rod of 0.5 m length is $8 0^{\circ}$ C/m. If the temperature of the hotter end of the rod is $3 0^{\circ}$ C, then the temperature of the cooler end is:

Options:

Answer:

Solution:

The difference across the rod is $80 \times 0.5 = 4 0^{\circ}$ C. The cooler end is at $30 - 40 = - 1 0^{\circ}$ C. B.
